content: I have needed a portable scope from time to time. Even 1MHz would have been fine. Picked up a couple of these locally complete with all the manuals and probes. Two different revs, fairly different designs.

content: The first one is back together. Needed a few parts and some cleaning. Other unit looks like it took some damage from a jolt to the front end. Knew it when I bought it. So far one of the clamp diodes was blown along with a cap. Op-amp and one of the 74HC switches looks bad. Both ELs are a little weak.Here's a 60MHz CW wave and a +1 tone wheel for an engine being simulated on the arb. Not bad for the age of it and how it was used.

content: Comparing with the BM8869s. First picture showing AC+DC / AC vs AC / DC. So the Fluke would be 4.806 AC+DC. It may have the math function for this. Have not spent a lot of time with the user manual.Next picture showing my bench supply set to 50 volts.Last showing some of readout functions. Not too bad.

content: The 97 has a built-in signal generator of sorts. The signal comes out on the two banana jacks. Shown with it set to ramp along with the highly modified UNI-T UT181A. The 181 can only log at 1Hz max.I ordered up some batteries for the 97 and have some parts ordered from Digikey to attempt to repair the second scope. Basically all that is left now is the signal generator is not working. The problem with it being so old is TI op-amp is no longer made. So more substituting.

content: Well,since we both got an old fluke scopemeter about the same time, I figured I would take your suggestion and add to your post. Mine is a 96B series II, 60Mhz scope with multimeter.I tore mine down tonight. Found a few problems but was easy fixes. Nothing with the components.Three out of the four posts that the main board screwed into were broken with the metal nut in case in the plastic. I little glue and all good, maybe dropped one to many times. The old battery leaked, some distilled vinegar and a little scraping and all good.The power transformer was being held together with one screw and a corner broken off. Not much to it inside. On 26V cap at 2200uf, 4 diodes for the bridge rectifier and the transformer. So some epoxy and it's now tying to set.The CR2032 battery is dead, I didn't notice any issues when I was playing with it. Maybe it hold the calibration data? But I haven't calibrated it yet, so maybe that's why I didn't notice. I need to buy one, I don't have any good ones currently. So I'll replace it before doing the calibration.Still need to find the service manual, not sure if the cal is done with software like the auto probe cal feature, or if it has to do with the 8 trim pots on the one board.I'll add the tear down photos in a later post.Nothing special, just some cell phone pictures.It took me a little bit to figure out how to post HiDef photos so every one can enjoy the fine little chips and the writing on the chips. I found out the shared URLs for photobucket and flickr both change the image posted. Now that I have figured it out I will have tear down photos up soon.For now enjoy the image of the full unit a and everything it came with.

content: Hey Scott, that was great deal you ended up with! The two 97's I have look a fair amount different in the main control board. The actual I/O (where the problem is) is one revision apart. Visibly I did not see the difference and they appear to interchange. There is no coin battery on mine.The charge packs are different as well. The one in the video looks similar you yours but marked Philips. My second one has a separate line cord.The second 97 is like yours, in there is no mention of Philips on the rear. I suspect it was made after they acquired Philips. It's much newer with the later rev I/O. The control board does not use the separate keypad. No jumper wires (there was one on the older unit). It is also marked "FLUKE 97/AUTO SCOPEMETER" rather than "FLUKE 97 50MHZ SCOPEMETER".I'm interested in seeing how yours differs.

content: Quote from: joeqsmith on November 09, 2016, 12:42:07 pmIm working on posting them now. I also updated my last post with some basic photos.Mine is also not marked with philips, and its a 96B series II that is a 60Mhz one also marked as a scopemeter.So even if mine has a lower number then your 97, it seems to be made after yours. Maybe the series II is the updated 96B that was refreshed after your 97's? But I have not looking it up to find out the release date. I do recall one chip had a date code of 1986, but I didnt check all the dates. Mine also had a lot more shielding plates.Im working on posting the tear down photos now.

content: As promised, these are the tear down photos in the highest resolution I could post them. You can always save the image locally to zoom in closer. They were not great photos taken with my DSLR and on a tri-pod or anything like that. It was a late night, just some extra lighting and my cell phone but you can still see a lot of the detail and components.You can even see the extra pads on the chips and how it the components are laid out since it was wave soldered. I think this is the second thing I have tore down that is waved soldered. I probably took apart more waved solder things when I was younger and over the years, but I didn't really know what I was looking at.I tried my best to post them in order to the tear down, but the truth is I took the pictures as I was putting it back together. So I hope they are in the correct order.I am happy to say it still works after tearing it down and putting it back together. This means my friend that gave it to me wont be mad also.To see the full set on Flicker"https://flic.kr/s/aHskNgtFM3

content: Very nice! Yours appears much newer than what I have. Looks like it has some help menus built in and the display looks much better than mine.I received the parts for the second scope today. As luck would have it the wall supply died while I was trying to debug it. Tore that apart and it looks like the connector that plugs into the scope opened up the center pin.The second supply had the same problem that someone had "fixed". I need to order up some new connectors.Changed out all the protection diodes and with the right ones and it appears there is a fractured joint or trace. Picture of my scope displaying the signal generator's output. It seems to be working solid now. All the waveforms work. Problem is, I have not found the problem!!Making some progress.

content: Well finding the plug to fit these may be slightly chanlanging because of how deep they seat into the jack.I'm sure you will find it, or make one.I still need to clean mine. You mentioned a signal generator on yours, I guess I need to read the manual to see if mine has this also. I know It will out out a standard square wave for the internal software probe calibration, but haven't done this yet.I think I'm going to go to the service manual first and run all the standard service tests then see if anything need to be changed or fixed. I didn't take it under the microscope, I guess I should have done this when it was apart considering the drops it must have taken for the posts to break.Well it's not hard to tear down. I may do this again and inspect the joints for any cracks. I forgot the older stuff like this might get cracks in the solder joints over time. But it was also wave soldered, so they are also glued on, maybe that helps preventing so,deer joints from cracking.I'm assuming yours was also wave soldered?Sounds like the repairs in the second one are coming along good. It might be done soon after you figure out that intermittent issue.Scott

content: I don't know how the board was processed. I would guess a wave or selective solder on the I/O board with as many TH parts and how the solder and flux looks. I did not pay attention to the controller board. They may have done some sort of reflow and selective solder on it.Your I/O board looks very similar to mine. Marked up your picture. The signal from the ASIC is fine coming onto the board. Looks like the first switch array is fine along with the FET. The output switch, filter and buffer are all fine. Diodes were shorted.It would be interesting to compare the power draw between them.Powered up defaults, 17.89V @212mAWith EL active, 304mAFastest sample rate with EL active, 326mA

content: I'll check the draw on mine next time I'm up in the lab.I did find some documentation on mine today, yes you were correct. The 97 was released in 1991, and the 96B along with three others was released in 1997.The numbering of flukes items messes with me. You would figure the higher number is the newer item. I ran into this when I was looking to buy my first fluke also and ended up with the 289. I guess that's what the "B" or "Series II" is for.I found the datasheet. Wow, a whole 30K of memory. It did enlighten me to real time sampling rate vs equivalent sample rate and random repetitive wave form capturing. Looking at this datasheet I was wondering how a mobile scope from 1997 claimed to have a higher sample rate of 2.5GS/s when my digital bench scope from Rigol DS1054Z only states 1GS/s. Now I know the differences.All I need to do now is find that 3.5 floppy disk it originally came with so I can use the optical cable from my 289 with this one. Oh wait, I guess I would also need to find a floppy drive. I think I still have windows 3.1 on floppy disks, lol.

content: Quote from: noidea on November 10, 2016, 06:59:12 amThanks, looks like some usefully information in this thread. I'll have to browse though itThis opens my options, I have plenty of 12V switch power supplies over 300mA output, most are 1A and higher. Still I'm sure the charging is done from inside the scopemeter so even with a better power supply this won't change the charge times.I did find that the unit will run off any voltage from 12V to 20V minimum of 12W output. And the original battery took 21 hours to charge for 4 hours of use, the original battery was also rated at 2000mAh capacity. The replacement battery mine came with is only a couple months old and rated for 4800mAh, so at the charge rate the meter give to the battery it woild take 2 days to fully charge my nicad pack. With the whole nicad battery memory issue it's better to fully charge and fully drain so I will probably use my RC hobby charger to charge it instead and 3D print some sort of box with battery contacts to hold the battery for my hobby charger.

content: Quote from: Scottjd on November 10, 2016, 03:46:38 pmLooks like I got the same pack of NiMH. Was expecting NiCad. I had picked up some standard C size 5000mAh NiMH as well. If it ran 4 hours, that would be plenty for what I plan to do with it.Also shown are the two different supplies. I ended up snipping the ends off both and just re-soldering them. When I looked at the one that had been repaired, it was hanging on by a couple of strands. Used a few layers of heat shrink to stabilize it. The T&B has a hot glue and once it cools, it's becomes stiff. You can get an idea how thick it is from the picture. Should hold up.

content: My pack is the same pack as yours, I mistaken thought it was a NiCd pack because all the manual mention NiCd. But I just checked, it's identacle to your pack, model number and all.As far as current draw it looks like we use different displays. Mine always has a backlights on it. The only thing I can adjust is the level of backlighting. It has three levels, it turns on at full since I am not able to save my setting until I put a cr2032 cell inside it.At full with your listed voltage of 17.88 it draws 208mAWith the light st it's lower it draws 192mAEven with recording the wave form and avaeraging turned up all the way to something like 256 it never went over 208mAThe same goes for reading a 1Khz test signal on my bench scope with both channels at the same time.(Sorry, I never got around to buying a signal generator)It also seems to have a parasitic draw around 8mA without the battery in it. I took the power supply and hooked it onto the battery terminals to see this.Scott

content: Ok, so it turns out no calibration is not needed. It was part user error and learning the scope interface.I just went though multiple tests and it did good.Not the best on reading mV, but for a meter built in 1997 it's about what I expected.All voltage AC/DC passed, multiple military grade resistor at 0.01% accuracy passed.It was also showing a message that it was on power when it was on battery when I changed the brightness of the LCD to high. A quick default reset seemed to correc this with holding down the F4 and turning on the power. You should hear multiple beeps if this works. I decided to do this since it had multiple owners and several setting were changed over time.All I had for wave forms was a cheap square wave signal generator besides the test frequency on my Rigol. It also tests PWM, not a bad little unit for $20 and a quick way to test components.I know I need to get an arbitrary waveform generator, I just never bought one. And for now it will have to wait, or maybe I will end up selling something to get one?If anyone has a broken HP i would interested in buying it for doing a repair.I took some pictures and then decided to shoot a fast last minute video. Not my usual video quality but like I said, it was last minute and not a planned video. So real fast basic editing, nothing fancy so l,ease don't judge.Scotthttps://youtu.be/2LsCQmjvCh0

content: Watched your video. Looks really nice. I really like the display.Looks like the problem on the second one may have been where the ribbon connects into the I/O board. Shown with it looping back. Sorry about the glare. You can tell this thing was no bench queen. It was used. Some chemical spills the etched the plastic and some pretty deep scratches to the lens.I measured the current on the other unit and got the same results, about 320mA worst case. Worse, they both draw about 32mA when turned off!

I don't know if a scopemeter is the way to go, though. For the price of a used old scopemeter, you can get a PicoScope, a Windows tablet and a roll of duct tape ...

content: Nice to see you figured it out. That cable on mine was pinched a little hard also. That was before I discovered that three posts were broken, it could explain the pinch. I thought about replacing my cable since it just looks like the weak spot now.I don't mind the screen at all, I like it a little better then the one the 289. The graphs on the 289 are simpler graphs. I'm also surprised how accurate it was cincidering the age and surface mount resistors. Im thinking either it was calibrated at some time, or wasn't used much so it never drifted. It was better then some of the reading I had from the 289 on the lower side around 5 Volts. Still both are within claimed specs.Sounds like they did get better over 7 year for power consumption with serries 2. Well that and chip manufactures were focusing more on power consumption with the start of the mobile revolution.The good news is the batteries we have are twice the original capacity.The bad news is the standby draw, I guess it's the battery charging part waiting to see the battery? I want to test my 289 now, but I also run it with eneloops so it doesn't really matter. Fluke told me it could be used with rechargeable, but it doesn't have a soft option to tell the 289 I'm using rechargeables so the battery guage isn't accurate and it cuts me off when I still have plenty of power in the cells. Sometimes it doesn't matter is you call the manufacturer direct, you still don't get the correct answer.I did notice when I was function checking it the battery still drained even when plugged in and in use. I checked the battery before and it was at 5.2v, after it was at 5.11v. So like a smart phone streaming music and screen on full bright while running GPS maps for directions. Wait, the smart phone can be fixed by using a 1A charger and not the stock USB port built into the car at 500mA.I also noticed the side with the charger was warm, and I didn't have the rubber housing on it.From what I'm reading the trickle charge with the fluke could end up being bad for a NIMH battery, especialy since it's main charge rate is so low. The NiCd charger with a slow charge rate and trickle won't know whe to stop trying to charge a NIMH pack. Maybe that's why the previous owner had a pack leak when charging.I found a 2800mA Ni-CD pack for $15, I think I would rather use than and not have to worry about it when it's plugged in. It will also take less time to charge, and 4 hours run time is good enough for me. I'll use the other pack for something else.Hmm, I wonder if my infrared to USB cable will work with the 96B serial communication port?What do you plan to do with the second one now that you have both up and running?How good does the single generator work on your models? I didn't even know they made one with a signal gen, kind of nice.Scott

FYI, I've changed my comments about the battery pack also. I think the reason the last person who owned mine had a pack leak was because the charger in the 96B is so low powered and then does a trickle charge. The problem from what I'm reading a Ni-CD charger st a slow rate with trickle won't know when to stop giving a NIMH battery more charge. So it will overcharge the pack mine came with.Scott

content: $50 on eBay, wow! I watched a 97 go the other day for $180. No accessories. I was looking at the temperature probe and people think that stupid thing is gold.The signal generator in the 97 is pretty much there just to cal the probes. I am not sure what else you would use it for as it can't do much. The slow ramp may be good for simulating sensors? No idea what the sinewave was for.My plan was to use them in the garage. As old as they are, I figure it will die at some point and I have a spare.I bought a NiMH charger with the C cells. My go that direction and just plug them in when I need to use the scope.

Hard to believe I scrubbed these in the sink.Does the 96 have FFT? What about AC+DC? What about Power measurements? Math in the 97 is very limited.

content: Quote from: joeqsmith on November 11, 2016, 06:30:20 amYour cable does seem a lot shorter then mine. As for math, yes it has AC+DC, I have not seen FFT as an option yet, I think I've gone over the whole menu so I don't think it has it. Also it was marketed to the auto industry and they don't have much need for the FFT feature.The manual has instructions for add, subtract, multiply, invert, intergrate, and filter, but in this section the manual has the 92B and 96B crossed off. I guess becuase the manual is for the 99B and 105B also.I know the 99B and 105B does 5GS/s andnhas extra memory for recording and saving wave forms also.As for power I can measure the current with a clamp as expected, see it as numerical or a wave form. But if I want to measure power with math function ii need the 99B or 105B again, not the 96B.I wonder if I change out the memory flash chips, if I could flash the new firmware to include the math function. It would probably be easier to buy a broken 99 or 105 and change the flash chips. Their is only two of them from Intel. It would give me the software feature in the firmware, but not sure if it's running any other parts that might be different also. I guess the one problem with buying a broken unit is if someone hooked up the 12V programming voltage backwards then it would have fried that flash chip. Somit would be a gamble.I'm thinking about buying some C cell rechargeables also, I think the one Ali-Ion charger I have already charges NiMh and Ni-cad but need to confirm this.If it does then maybe I'll just break down the pack it came with.

content: The old 90 series ScopeMeters have some surprising features in comparison with the later 120 and 190 series. For example it can display up to 5 simultaneous measurements for a channel. The much newer 120 series can show only 2 simultaneous measurements per channel (primary + secondary or primary + cursor) and the much more expensive 190/190B/190C series is actually even worse: It can display only 2 measurements in total (two for one channel, one for each channel or one + cursor). The latter has been improved in the newest 190 Series II, though. The 120 series do not have any math capabilities although the 125 can do power measurements.

content: Quote from: Scottjd on November 11, 2016, 08:49:07 amThe cable is around 2".I figured with yours being newer they would have the AC+DC. That's nice! When I looked at the service manual, seemed the controller they used could have handled it. Looks like a masked part.There was a note about measuring power with the 97. I think they were just talking about the multiply. I was thinking with the newer ones they may have added enough math to handle at least 60Hz sort of signals. Not that it would ever make a good power analyzer.Strange you don't feel the automotive group would have much need for an FFT. That one feature alone would be a great diagnostic tool to detect all sorts of problems. At the tech level, it may need to be wrapped into some fancy software to make it easy for them to troubleshoot. I agree that most techs would not know what it is, but they may have equipment that uses it.Buying eBay and used in general always has some risk. On the plus side, most people who bought these would never touch the 12V programming pins. They may drop them, throw wrenches at them in anger or spray them with break cleaner but not try can align them.I plan to just use the thing.I was thinking to cut my pack apart as well. I don't have a way to charge it and doubt the internal NiCad charger could handle it. I bought 8 EBL batteries with their charger. Their all charged up now and I'm planning to run some life tests with them next.Maybe that Bartterizer thing would work. Switcher on switcher may gain us something

content: Quote from: stj on November 11, 2016, 05:46:57 pmI wonder if this is what haolend to your second one Joe? Wouldn't surprise me. Mine had the leaky pack, sommaybe mine got lucky or they improved thencharger with the serries II B models.Either way, the charger is not suitable for NIMH packs. I can't believe the one company sells so many of these NImH replacement packs. But playing devils advocate if your in the shop using it every day you will probably rarely hit the full charge point on a 4500mA pack that would take 48 hours to fully charge (weekend off) with the internal charger. So maybe that's why people haven't complained, or noticed. Me, I know I won't use it every day so the risk is higher.I think the internal charger would be OK if you find a Ni-cad pack replacement. I did find one on Amazon for half the cost of the NMHd pack, about $15. But I also had a leaking failed pack, I should ask my friend if he still had it. I'm curious to know if this pack was the original Ni-cad or a newer NMHD packs that failed. It will give me a clue if any damage was done to the charging circuit.

A few of my friends are mechanics, and I once when I mentioned FFT he looked at me weird because he didn't know what I was talking about. These days with cars having 23 different computers I'm sure many features on a modern scope woild come in handy. But diagnostically they are used to plug and play with the ODBD II plug and go.....Good point also about the 12 programming flash being ok. As for the break fluid, it's all good. I have break cleaner so I can fix that oneI think the batterizer will definitely help out with the parasitic drain when the units and standby. We should buy a couple, oh wait they haven't sold them yet. I wonder what's holding them up?Let me know how the new batteries work for you. I did see something in the manual for a mode you can use to turn on the unit to refresh the battery. It sounded like it just disabled the sleep timer and the battery voltage detection. If the battery is under s certain level it won't attempt to charge it unless you use this mode. They said to drain it under this mode, then charge, then repeate 5 times.Well if your has this mode you could set up a Time lapse to determine the run time with the new batteries.I forgot my eneloops came with a AA to C cell adapter, the AA are rated for 2000mA. Maybe I should try this, I should be able to get 4 hours out of it, maybe. And I own about 16 AA and 8 AAA eneloops with two charger already.

content: Quote from: Scottjd on November 11, 2016, 06:26:56 pmThere are several 7.5V back to back zeners that are part of the input protection. These are what was damaged. Someone hooked it up to something they shouldn't have. The cable was just a quick removal and clean. I think this was just age and heat cycling in the garage that did it in. The other problem with this meter is the rubber gaskets are starting to fail. Maybe from age, maybe from the break cleaner.It's also missing the boot. Too bad they don't have parts available for these. I would consider getting a new shell for one with a lens and keep one as a shelf queen.For the FFT, I could see looking at vibration. Real fun would be to look at crank position with an index. Image, you could see every stroke and know how each compares. I'm not a mechanic and really have no idea what is out there for tools now. You can't get to everything with the CAN.I already received my Baterizers.

Hmm, maybe an electric flyswatter?I've attached the part inwas refering to out of my manual that shows how to disable the battery save sleep mode. This may be just in the newer serries II firmware? But thought you could try it and see if it works on yours.I looked up the battery save feature, another fancy way to say sleep timer. I was wrong before, it had nothing to do with preventing the charge of an over discharged pack. But it should allow it to stay on if it works for a run time test.

I then turned it on and left it. It ran about an hour fifteen. The high current draw when it is off will be a problem for me so it looks like I am going to charge and just store them until I need to use it.

content: Quote from: joeqsmith on November 12, 2016, 05:53:08 pmWell I guess and ignition coil throwing 20KV to 30KV would make more sense.The manufacturer of the battery replied to me, they are sticking to the common math for charging rates of charging based off the capacity. So if it's a 1500mA capacity battery, the max charging rate would be 1.5A.Of course charging at full speed does decrease the cycles of the battery lifetime.Still don't trust that it's a real 4500mA batter. So I think I will top it off with 200mA slow charge, then drain it on my hobby charger at 300mA since the meter won't pull more then 300mA. Or maybe for mine a more accurate representation of drain woild be 200mA.Scott

content: Nice, maybe that's the best way for me to go ask then. Was that with or without the light on yours.I think you said without the light was about the same current draw as mine in full brightness.Your batteries are 5000mA cells, the eneloops AA I have still the C converter is about 2000mA per cell.So if you had your lights off, I think the eneloops would do about 3 hours with my light on low since I can't turn my light off. Three hours is good enough for me considering I own about 26 AA eneloops cells (RC transceivers take 6 to 8 at a time) and could carry two sets if needed giving me 6 hours. Way more then what I would need. I just need to see if Panasonic sell the adapters from AA to C selerate. Thenkot from Costco only came with 2 for C and 2 for D cell adaption.

content: Quote from: joeqsmith on November 13, 2016, 02:44:10 pmWell I ran it last night with the backlights on the medium middle, all I have is low, medium and high.So I chose medium and set it up for diod mode so it was putting out 3.7 Volts. Then wired a diod on the clams and it dropped to 0.480V, extended those leads to my Fluke 289 that also displayed 0.480V.Started mid max on the 96B and record on the 289. I wasn't sure if the 96B would hold the timemof mid max if the batteries died. Turns out they both agreed at the end.When I graphed the 289 you see the half a volt drop to zero assuming this is when the 86B turned off after 2 hours and 3 minutes.Then I did a recal on the 96B and it agreed on the 2 hour run time. So for 4 eneloops AA 1900mA cells charged 4 hours before so they had time to settle. Oh, and I checked the draw, it was 750mA draw when running on the batteries in the above mode.Now that I know it holds the mid max before it turns off I set it up again with 4 eneloops last charged about 6 weeks ago, they all averaged about 1.33V. I set it up again on the middle lighting with it measuring the test signal from the Rigol scope and enabled mid max again. Let's see if scope mode does the same 2 hours as meter mode.Oh, and I found several AA to C adapter for 3D printing. So no cost for those. I even found one that uses 2 AA in serries to a D cell adapter for double the capacity. I think I will print some of these out just to have them on hand, a just in case situation.Scott

Yea, the 750 you measured seems right.Not sure putting two 1.2V cells in series to replace a 1.5V D is a good idea. They do make some pretty decent D NiMH.Ha! Yea I ran into that problem with the 97. I plugged it back into the charger at the end but my data was lost. It may have ran 8 hours, I'm not sure. Something over 7. It appears your 96 may be the same physical size as the 97. Maybe they share the same gaskets, boot and lenses. Had a look on eBay for another junk one at a decent $50 price. No such luck. I'll try calling Fluke service and see if they have any stock on at least the gaskets.

content: So I charged up (sort of) the green battery pack using the bench supply and it's been in the scope a few days. I've been playing around with the scope and was surprised it had not failed yet.Snipped out about a 0.5" X 1" section of thin plastic. Stuck some foil tape on both sides then wedged it between one of the connectors and the battery.When the 97 is off, it draws 184uA. Much better than the 32mA I measured from the charge jack. Once I turn it on, it draws 584mA (without the EL). Seems a little low. Makes sense now that the 5000mA/h batteries did so well. Would be almost 9 hours. Maybe once they have been cycled a few times, I'll measure it again and record the time using the PC so I don't have to watch it.

content: Nice thread and an interesting read.I still have a complete boxed 'as new' PM97 sitting in my lab. I have kept it in case it was ever needed but sadly it has never been out of the box except to test it. The Ni-Cad pack died long ago but it is is very easy to fit four standard Ni-Mh C cells and just add a small brass or copper strip that sits between the positive connection nipple and the charging tab that is below the battery. It is even easier with a tagged cell as the tag is sometimes long enough or may be extended to reach the charging tab.I will be re-homing my lovely PM97 set soon and I am open to reasonable offers if someone wants an 'as new'example with all manuals leads and PSU. I also have the dinky little demo signal board that FLUKE manufactured for testing the Scopemeters. Finally I have a lot of the optional accessories and scope probes that FLUKE sold for these units. Really nice quality but sadly they never see use in my lab. If there is no serious interest here, I will list the bits in the Forum's For Sale' area where it really belongs, then onto eBay if no home is found on this forum.FraserUK

Prices are all over the place. IMO, it's 20 years old and parts are no longer available so it's not worth a whole lot to me. I see them for $500 up USD! Used color 196 will sell for less! Buyer beware. I was able to basically fully check mine before buying them which swayed me along with what they were asking for them. The battery packs are not much. I think it's a 3000 count meter is all. Specs are not that great but it's 20+ years old and fits in your hand.

As it is 'as new' it has all the little extras, like the quick start guide that has magnetic front and rear covers and sits in the rear of the yellow 'boot'. In its day, it was perfect for automotive and portable usage where isolated inputs were a requirement.I have always been surprised at the residual value of these units. I sold a pair of well used PM97 units for £160 each last year and the buyers were delighted with them. The price of spare scope probes is scary. They are good quality but you certainly pay for it. I have several spare scope probes and some of the optional modules that plug into the scope inputs. I will dig them out and take some pictures for your interest.Fraser

content: Quote from: Fraser on November 16, 2016, 05:13:47 pmHi Fraser,I wouldn't suggest charging the NiMH pack with the 97 or 96B internal chargers. I mentioned this in an earlier post with some testing I was doing and research during my testing.They are designed to charge NiCd batteries and NiCd chargers have a hard time detecting when the NiMH pack is full especially at the low current rate the scope-meters charge with. Negative Delta V to detect full charge is faint, especially when charging at less than 0.5C. The older fluke scope-meters charge with a very low current, and in addition are designed to trickle charge at a higher rate that NMH will be damaged. The built in chargers will most likely over charge the NiMH packs possibly damaging the packs or even the meters.I know companies are selling NiMH packs claiming they are OEM compatible, but I don't think the are. I have torn down this pack and it has no additional circuitry for charge monitoring built into the pack. NiMH dislikes overcharge, and the trickle charge is set to around 0.05C. NiCd is better at absorbing overcharge and the original NiCd chargers had a trickle charge of 0.1C. The differences in trickle charge current and the need for more sensitive full-charge detection render the original NiCd charger unsuitable for NiMH batteries.I did find one seller on Amazon that sells a 2500-2800mA NiCd pack that should work good with the built in charger.I'm looking into doing a mod installing another DC port that will disconnect the lack from the main board when it's plugged in, and change over to the charging tab when a DC plug is plugged in. Then I want to find a small charging board like the TP4056 but for NiMH packs.I want to put this inline after the switch mode power supply or micro USB power supply before the DC jack and heat shrink it. If I used a micro USB board then this can be a simple adapter to use with the older scope meters with adding the DC port to charge NiMH at a faster rate and proper charging and voltage cutofff for a NiMH pack.The wires in the battery cage are easily accessible to add this additional DC port and wire it as I described without any additional components.I just started searching for this NiMH charger like the Li-Ion TP4056 charger. I don't know if anyone makes this already. If not then it might be a self build. By wiring it like this I would also cut off the built in fluke charger so powering from the fluke power supply is still an option and you would also be able to plug in the additional DC jack I mentioned to charge at the same time.Thank you,ScottTP charger I refered to that I'm looking for, but inenthat does NiMH charging instead.http://www.ebay.com/itm/like/142004893160?lpid=82&chn=ps&ul_ref=http%253A%252F%252Frover.ebay.com%252Frover%252F1%252F711-117182-37290-0%252F2%253Fmtid%253D1588%2526kwid%253D1%2526crlp%253D53601919689_324272%2526itemid%253D142004893160%2526targetid%253D186358894329%2526rpc%253D0.26%2526rpc_upld_id%253D91632%2526device%253Dt%2526mpre%253Dhttp%25253A%25252F%25252Fwww.ebay.com%25252Fulk%25252Fitm%25252Flike%25252F142004893160%25253Flpid%25253D82%252526chn%25253Dps%2526adtype%253Dpla%2526googleloc%253D9014901%2526poi%253D%2526campaignid%253D239125209%2526adgroupid%253D14978428809%2526rlsatarget%253Dpla-186358894329%2526gclid%253DCP3p-pKquNACFVUvgQodoP4JlA%2526srcrot%253D711-117182-37290-0%2526rvr_id%253D1126736449119&ul_noapp=true

After seeing your comment it got me thinking again. And I just picked up 5 different Li-Ion battery packs for tools from different manufacturers for tear down. These packs usually sell about $40-$65 US and I happened to get lucky walking around a department store. The clearance isle was calling to me, I paid $5 each for three of them. So far all two of them have quality Samsung 18650 cells.So after relying to you I realized the 96B runs off of 12VDC to 18VDC, and the charger I mentioned is nice and small. Now I'm wondering if I can make a custom Li-ion pack using this small charger.The battery is 4.8V nominal, but the DC input external power jack will run off of 8V to 20V @6W.Maybe 3 high capacity small Li-Ion cells wired directly to the external D.C. input jack. I'll have to take a look inside again and see how much room I have since I will need 3 cell protection and a way to balance charge them also. But your comment defiantly got me thinking again.

Installed the pack today and then used the diode test mode you suggested last time and logged the data with a second meter. First time I tried the pack without charging right from the box after it had sat in the scope with it turned off for a day and it ran for an hour fifteen minutes.This time it was not much better. Looks like it died at 6279 seconds. No where near the other batteries. So 584ms @ 1.744 hours gets us 1000mA/h?! These things can't be that bad but I'm starting to believe some of the reviews people wrote about a half hour run time.

I use these if I need more current then I can generate on a power supply. Like testing an inverter.One is a hobby charger, that has a discharge feature and tracks the mA used the skame as it does when it is charging. I created a jumper wire with two earth magnets to jump the pack and will charge and discharge a few cycles. I know my pack is only 3 months old.I will then set the discharge rate to simulate the draw on the 96B around 260mA (I think that is what I measured) current drain and see how long it holds and how much power this pack is really storing.I'll measure my drain on the 96B again to confirm.I can do the same with the drain based on your 97, what was the drain you meter uses?

I think this has to do with the date and battery manufacturer. I bet the stamps on the back our different.I'm discharging all 4 cells at 1A rate. So far it's drained about 1228mA over 74 minutes and sits at a cool room temperature of 22C. Voltage is 4.64 under the 1A load, and was at 5.12V without a load before I started discharging. It dropped to 4.92V inner initial load.I'm almost at the estimated capacity your pack was showing and still going strong.I'm guessing you have a bad cell or one cell way off balance, that's the problem with the older Ni-MH and nicad packs. When I was a teen we raced RC 1/10th scale cars with nicad packs, of one cell died we knew it from the decreased run time. We could always recover the pack by replacing the bad cell, but it would never be the best pack for a race so it became a practice pack.I have it set to stop at 4.1V since I don't know how well these cells are balanced, or if it was properly trickle charged and topped off. I'm guessing probably not since it was last charged with the fluke 96B nicad built in charger.When it stops at 4.1, I will drain more at 300mA current again to 4.1V.I'm going to charge it at 1A also, well maybe I will start at 2.5A charge and monitor the temperature. My charger has an external temp monitor and I have it set to turn off if the pack reaches 32C durring charging.I did discover tonight that the temp monitoringndoes not monitor during discharge, only when charging doesmit monitor and fail safe if it hits the set temperature.I contacted the manufacturer and they confirmed it will handle a 1C charge rate at 4.5A, but also hinted that I should charge it at 500mA to 1A. I guess they don't have faith in the packs they sell.At the time of writing this it's currently at 4.53V, with 1645mA estimated drained over 100 minutes, still draining 1A current.

content: Here is the code on mine.Charger is still doing it's thing. Was hoping to shove them back in the scope and catch some sleep. Could be a bad cell and why I have been watching them on the charger. They all seem to be at roughly the same voltage. Nothing getting warm. This charger is fixed at 1A charge and 300mA discharge.Can't believe that low current fixed voltage did anything to it. I wouldn't snip yours apart just yet. Let's see if the independent charge does anything for this pack. Worst case, it becomes a flashlight pack....

content: Quote from: joeqsmith on November 25, 2016, 08:55:40 amOk, my code in the back is.My discharge just stopped, but at 4.4V. I thought I set it for 4.1, but I probably set each cell at 1.1. Someday I will be able to do simple math againSo it took it down 2000mA, I will put it back on now to drain to 4.1.I wasn't going to cut my cells apart, but I might unwrap them to see the numbers. I have PVC heat shrink for 18650 cells and should be able to use this to wrap them back up and glue the two cells next to the other two cells again. I should probably measure the diameter of these cells and the no shrunk diameter of the PVC I have first before doing this.We picked the wrong night to go charging batteries we don't trust after eating turkey. Ok, I didn't eat any turkey yet but I'm assuming you did. We postponed our dinner until Friday because of a long night last night in the ER. Then I took a nap this at 1pm, it was supposed to be a short one like an hour but didn't wake until 6pm so I'm still wide awake.

content: Quote from: joeqsmith on November 25, 2016, 07:39:44 pmNice, that's longer then I originally estimated. Oh wait, I never estimated the run time. I only estimated charging time for the pack with the built in charger. Over 8 hours, wow. Then maybe the 96B might pull over 10 hours.I was lucky and managed to get a real keysight GPIB to USB adapter, not one of the many fakes on eBay. I think I installed the driver and changed the run mode on the application for backwards compatibility in the properties of the executable. I don't remember the details and bought a new laptop so I don't currently have the software installed. When I ran my run time test I use my Fluke 289 for logging. I need to set the remote interfaces and software back up again on my new laptop someday.

content: Quote from: joeqsmith on November 26, 2016, 12:37:40 amI wouldn't use any of the built in charging for the Ni-MH pack. I was thinking about this idea I had. Feel free to add to the idea or give feed back about it.For charging a Ni-MH lack in the meter I was thinking about the following idea.I would add a female micro/mini USB port that I can splice into the positive battery cage tab. Then using a power supply to supply power to a Ni-MH charging boar I can put it inline between the power supply and before the male USB plug. Maybe I can 3D print a bigger housing for the power supply and put the charge board inside this housing with a plastic wall for separation between the power supply and charging board.Maybe start off with something like this one, or use one of the cheap chargers I don't trust that came with some LED flashlights and mod them?http://www.ebay.com/itm/Ni-MH-Charger-Auto-Stop-Circuit-board-1-to-10-cell-800mA-MJE2955T-12-16VDC/140353600313?_trksid=p2045573.c100033.m2042&_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D38530%26meid%3D302ca39224134343948c276a38f87bf0%26pid%3D100033%26rk%3D2%26rkt%3D8%26sd%3D401046168634I would wire it so when the USB port is plugged in it will disconnects the positive line from the battery packs to the meter preventing the meter from running off the battery when it's charging. Then provide the positive line from the charging board to the battery positive terminal, not the charging tab. I would disconnect the wire from the onboard charger to the battery cage. This way you can also plug in the stock power supply to run the meter at the same time it's charging the battery from the USB port. This will also allow standard Ni-MH C cells to be used without a need for a charging tab and could charge them from the USB port. Also running standard C cells will be easier to check the individual cell voltage and replace a bad cell if one dies.Interference from the charging board should be minimal since the charging circuit will be external and away from the meter with at least 3 feet of wire or longer.The charging board would have an adjustable charge current controlled by a resistor pod. I can use a in line USB power monitor for adjusting the current so I won't need to put a display on the charging board. My USB power monitors from YZXStudio runs from 4V to 14V with little burden voltage and little power consumption.My concerns would be the charge rate and the heat generated on the cells as they increase to full charge capacity in that little battery compartment that is sealed with an O ring. I can use the USB data lines to a K style thermostat or thermistor that I can hot glue the sensor inside the battery compartment. Then include a temperature cut off monitor on the charging board when it reaches a set temperature. I did read about a Ni-MH charging method that was based off the temperature only. The charger turns off when it hits a set temperature despite the voltage levels. This charging style is new to me so I would need to research it but it makes sense. I would also want voltage monitoring as a backup cutoff.If the pack doesn't get too hot when charging then I can set the charge board to put out 1A or maybe higher for a faster charge. NI-MH batteries are designed to charge with higher current and they could over charge with low current like from the built in Ni-CD charger. The built in charger won't be able to detect when the cells are full when it's doing a trickle charge that would over charge the NI-MH cells.I will probably just disable any trickle charging on the Ni-MH board so it might drop the total capacity when it's done charging the pack, but not much loss difference in capacity. It will still have plenty of capacity for long run times and shorten the charging time a little. This way the Ni-MH pack would charge faster with temp cut off as the cell fills up to near full capacity as they reach near full charge.TIP:I soldered a pin to the end of an old probe (or you can solder it to the wire with a male bandanna on the other end) and poked little holes in my pack so I can check the individual cell voltages without unwrapping the pack. I wouldn't recommend using this pin probe for LiPo packs since they are easier to puncture.So far mine seem fairly balanced, well within spec for what I would expect from a Ni-MH pack without balancing capabilities. A little trick I used to do with RC packs to check for a bad cell without having to unwrap the pack. I used to charge the packs at max current. Heck the old Ni-Cd packs we used to charge them in a ziplock bag then put into an ice cooler so they would take the max capacity and have a longer run time. It killed the packs faster as expected, but it was racing so competition brings out inventive ways to win within the rules.I know my charger is a delta charger, so I can set the mV for the trickle to top it off or leave it on automatic. This was an idea to top off all the cells to the same level. Not sure if or how it really works. I just kept it on automatic. I changed over to LiPo packs shortly after this and stepped into the next class of races.Thank you,Scott

content: I have not looked to see how they connect in the scope. Assumed it was 3 wire + com -. Normally when I need a scope like this, it's for under an hour so 7+ hours is more than enough. I did contact Fluke about trying to get parts for them (holster, gaskets, etc) and they have no parts available.It will be interesting to see what you come up with. Maybe you could strip the entire power supply section, use the connector that is on the unit and start clean rather than trying to work with what it there.

content: Quote from: joeqsmith on November 26, 2016, 04:58:24 pmI did think about stripping the whole power supply section and starting clean, but I also like the fact that it current will run off of 12VDC to 20VDC on the current DC input. This give a lot of options for powering it and handy for automotive, just jump to the battery and it's on. I'm not sure if your 97 is set up the same way?The other concern with starting fresh was inadvertently causing interference with what you are probing. This is why I was wanting to put the charging board at the power plug and not inside the unit, and also disconnecting it from the unit while it's charging the battery to prevent any interference while it's still being powered from the DC barrel 12-20V input.I think I may have a dual power supply in the box of power supplies, I'll have to see how good the separation is on it and scope the signals. I may be able to use a dual and just split the wires so one is the USB for charging and the other is the DC barrel. So only one thing to plug into the wall, and since it takes a wide range of power input with 12-20V this opens up options for finding a good dual power supply.I don't have an immediate rush or even have a daily need to use this scope, so it may be a back burner project but something I still think would be fun to do. I'll keep the thread updated, I'll probably have to come back to the thread to see my own notes an idea any way

Many times I have needed a scope, I did not have a power source I could plug into and had to run extension cords to power my old analog scope. For the car, I would run a converter to get the 120 to power it. Imagine having an analog scope sitting in the passenger seat.A little harder to strap it to the bike!You could print a whole new back cover for it and put what ever you want for batteries in there. No reason to lock yourself into what's there.

To high for the battery powered rail, not high enough for the minimum sustained voltage of 8V if I spliced it into the DC power input jack.So three cells would be needed, but three 18650's won't fit. Maybe three 14500 but then the capacity is low.It would also need room for protection on each cell so if one fails it won't have a thermal runaway into another cell, and then the balancing added parts as well.

content: Here's another model from the 90 Series: TheFluke 98 Automotive ScopeMeter Series II. This model was aimed specifically towards automotive applications and operators without electronics background. Instead of manually using cursors and measurements, you select what you want to measure in advance: An oxygen sensor, ignition signal,... The ScopeMeter will then automatically set the most appropriate measurement mode and readings. The device can be used as a plain oscilloscope, but the feature set is extremely limited and the lack of dedicated oscilloscope buttons makes operation convoluted. Like all other ScopeMeters the Fluke 98 can also be used as a digital multimeter but the large size, weight and, again, user interface, make a simple digital multimeter a much better option. Nevertheless it's a great tool to diagnose older cars.The Fluke 98 comes in a nice Fluke hard case with an assortment of leads and probes for automotive applications. Just like Fraser's PM97 ScopeMeter, a tiny demoboard is included to get the user familiar with the meter's features and operation. The Fluke 98 was also rebranded as the Bosch PMS 100, Opel TECH 31 and possibly others.The main difference between the Fluke 98 and the rest of the ScopeMeter series is the software. The hardware is mostly identical although the bandwidth is much lower: 5 MHz instead of 60/100 MHz. The rest of the specs are pretty much identical.Two major revisions exist: The original 98 and the 98 Series II. The most obvious difference between the two being the display. The original had the green display with weak backlight as seen injoeqsmith's pictures of his 97 ScopeMeter. The latter came with the high-contrast black-and-white display with permanent backlight as seen in thepictures of Scottjd's 96B ScopeMeter. I was unable to find a manual or even spec sheet of the original 98, so I have no details about other differences between both revisions, but some accessories like the DIS 90 work only with the 98 Series II.The Fluke 98 Automotive ScopeMeter Series II owner's manual is available on the Fluke website (download link). Sadly, no service manual is publicly available.

The newer 120 series ScopeMeters had already been introduced a couple of years before and the faster 190 series was about to be released. By the way, both 120 and 190 series use a similar keypad foil so clearly Fluke thought it was a good idea.

The filter has 6 pins !3. I can see a nice thick power track coming off of one of the filter output pins.4. There is a thin track coming off the other pin of the filter and this is unlikely a power track. More likely a sense line.5. There are two additional pins at the mid point of the filter. One of these could be the second power rail output.6. The filter contains only 3 ferrite cores instead of the usual 4. This may be the reason for the non standard footprint connections.I suggest you carry out continuity checks on all 6 pins of this filter component. I do not expect it to be the cause of your problem. There should be at least two pairs of pins showing Zerp Ohms continuity and possibly an additional pin showing continuity with the positive rail as a sense line.Fraser

After repairs, this scope on the rights EL was very weak. I finally got around to picking up one of those cheap white ELs.

I am also using an iPad screen protector that I am cutting down to size to protect the lenses. I will do the same to this scope. That stuff also gets my vote. Easy to work with, sticks and comes off without residue. The LENS6 has the protective film installed.Down side is for deep scratches afraid it is sand paper time. Even 1000 grit took a while to pull some of the bad scratches in the 97. It would have gone better to go from 1000 to 1500 to 2000 before starting to polish.

content: I have one that is slightly different than what was posted here already.It is branded on the front as Fluke 97 Scopemeter / Philips on the back. Serial number DM547XXX.The main difference between modes is in the flash memories. According to fluke website (if the link does not work go to manuals -> search for: 97):https://dam-assets.fluke.com/s3fs-public/93_95_97mveng0000.pdf?_ga=2.14758966.1275149489.1535696131-345369494.1535440239Document says:Model:Fluke 93, 95, 97, 97/AUTOProduct Name:ScopeMeter Series I Test ToolInstrument Description:The Fluke ScopeMeter Series I test tools provide an up to 50 MHz handheldoscilloscope combined with a 3½ digit DMM.Memory Description for instruments with software versions belowV5.xx:The Fluke 9x has the following memory devices:1.D1207 (N28F256-A200, 256 kB or N28F010-200P1C4, 1 MB) and D1208(N28F512-200P1C4) flash EEPROM for instrument firmware and calibrationconstants.2. D1204 (HM62256, 32kx8 SRAM) and D1206 (HM62256, 32kx8 SRAM) forsaved test tool settings (Fluke 97 and 97/AUTO), saved screens andwaveforms (Fluke 97 and 97/AUTO), LCD bit plane data and measurementdata.Memory Description for instruments with software versions V5.xx andhigher:The Fluke 9x has the following memory devices:1.D1221 (E28F010-120, 1 MB) flash EEPROM for instrument firmware andcalibration constants.2. D1232 (M5M5256BRV, 32kx8 SRAM) for saved test tool settings (Fluke 97and 97/AUTO), saved screens and waveforms (Fluke 97 and 97/AUTO).3. D1218 (M5M5256BRV, 32kx8 SRAM) for LCD bit plane data andmeasurement data.It looks like those with memories N28F* are older and those with E28F* are newer. According to the pictures posted in this thread and over the web also series II uses E28F* memories.I see that Joeqsmith has one unit with single N28F* memory and the other with single E28F*.https://www.eevblog.com/forum/testgear/old-philips-fluke-97/msg1063314/#msg1063314My unit has two N28F* flash chips: 512kB + 256kBWhy I'm doing this brain exercise you say? This is the interesting part from the Fluke document I already mentioned abowe:Memory Cleaning Instructions for instruments with software versionsbelow V5.xx:1.The operating code (instrument firmware) stored in D1207 and D1208 can beread using special remote interface commands.The instrument firmware canbe loaded using a dedicated Fluke software program. Calibration constants stored in in D1207 and D1208 can be read usingspecial remote interface commands. The calibration constants are generatedwhen the meter is sent through its calibration process and are fundamental tothe test tool operation.These scopmeters can hold just 3 calibrations (one of them is probably done already in factory) and then memory is full and you need to bring it to Fluke where they will blank the memories by reuploading firmware. Maintenance manual excerpt attached.There is also interesting part that mentions Kernel restore procedure - see attachment.User's manual also mentions that firmware from V4 up adds new functions which I dont have in my unit. For example: Duty cycle, timestamps during min/max recording, 30ohm range...My questions are:1.) Is there anyone out there having the firmware for one of these? (preferably from unit with two N28F* flash chips)2.) Anyone did some hacking using serial cable to get something out? Firmware or calibration data? Any hidden instructions to be send to the scope?If nothing then I hope that at least this post can serve as the starting point for someone more skilled then me.Regards,Tomas

content: Probably no.According to this post sending command "ID" should get the firmware version. I myself don't have the cable yet but I have ordered the parts already.https://www.eevblog.com/forum/testgear/philips-pm93/msg967424/#msg967424I know only how to check how many calibration slots left... you've got to enter calibration mode and then press Escape not to store anything... (attached instructions).For me it is 2 free slots so my unit was probably never calibrated after it left the factory. Meter mode is mostly on the lower limit of tolerance when comparing to my BM 869S. I don't have anything acurate enough to check the scope performance.

content: I read almost the whole Service manual and it mentions the way how to display firmware version without serial cable.It was hidden under the Error messages and the cause of the firmware version "error" message is:Turn the Scopemeter on and then press first and last softkey at the same time (the buttons in the first row under the display)Mine is V3.15 from year 91. Serial number of my unit is DM54 XXXX.Anyone wants to share his version?

content: Well, in the end I would like to update my unit to the latest 4.X version firmware and also have the posibility to do more then 2 remaining calibrations (which also requires the re-flashing of firmware).I don't see a way to make it happen at the moment. Perhaps desoldering the flash memories and backing them up would be a good start. Then someone much smarter then me would need to analyse the content and come up with the secret Fluke commands to download the FW via serial cable. If we have the commands, someone with a good will and the new unit could download the FW and share...Anyone with the programmer, soldering station and a steady hand willing to risk it?

content: Another piece of infomation found:Microprocessor in (my) Fluke 97 is Intel 83C196KB. According to the service manual it has onboard ROM containing boot loader and everything needed for serial communication and the main Firmware upload/download.That narrows down the options to these two:1.) desolder external Flash ROMs, make backup via programmer, put them back preferably using the sockets -> now we have the option to start over with the same firmware and the current remaining number of calibrations2.) desolder the microprocessor and dump the internal ROM via custom built jig, then reverse-engineer boot loader to get the secret serial commands for upload/download of the main Firmware -> now we have the option that anyone with serial cable can upload/download the main Firmware and hopefully share it with us less fortunate with the old FW versions and also get the chance to do more then 2 calibrationsThis is what the Intel's users guide says about the ROM dump:For the 83C196KB,the ROM Dump Mode is entered by placing EA at aTTL high, holding ALE low and holding INST andRD high on the rising edge of RESET. The device firstverifies the security key. If the security keys do notmatch, the device puts itself into an endless loop ofinternal execution. If the keys match, the device dumpsinternal locations 2000H-3FFFH to external locations4000H – 5FFFHMy guess is that the ROM is read protected and the custom jig must be bulit with the memory attached on the mentioned addresses and the jig must have the capability to automatically restart microprocessor so the brute-force attack can be made.Option two is obviously better but is far beyound what I can do with my equipment and especially my spare time.

content: or if the bootloader does not hash-check the main flash, you insert a routine into the main code to dump the address-space to the uart.even if it does, it may be a safety, rather than security thing with some simple check like CRC32 with the result at the end of the flash.

content: I suspected that when I saw the first part empty, I did test the chip to see if it could be written to and read from reliably and it seems to be ok in that aspect, I remember it working fine before I stored it away, after a year I put it on charge and thats when I noticed it had stopped working, I think the battery may have leaked and shorted the 12v flash enable connectors in the battery compartment which might have caused the flash chip to erase, that's the only thing I can think of that could have caused it, I have searched high and low for a backup of the flash chip content but have had no luck at all.

content: I just found this thread while looking for info on the PM97. It's been a while so I'm not sure if anyone is still interested but I have a couple of things I can add...For Hairystuff, I had a quick look at flash file (thanks jellytot - very useful) and it appears that the code is the same for all 3 versions. Early on in the code location 0x0106 is checked with bits 0,1 or 2 being set for 93,95 or 97. The value in the file is 0x14 so I'm guessing if you change it to 0x11 it will run on a PM93 (providing you have the early hardware with the keyboard on the main pcb)The MAT/CAL routines posted by harrimansat were also very interesting, you can display how many calibration slots are available without having to apply the 12V programming voltage by sending the serial string:2.277 PORT PS1,FF3B025F00CF3E10002C000001000300090000020000008A0082.277 PORT 000000274002221376611021A0010A680808080808080808080800F2.277 PORT AA000E0A1F2400000001000002000200000000000000000000000002.277 PORT 00000000000000000000000000000045830EB2F00000000000000002.277 PORT 0000000000000000Also, I had to make an adapter so I could use the currently available IR189USB serial lead with the PM97. I've attached the STL file in case anyone else wants to 3D print one

content: I have a working 97 with one NF28010, and, a working 97 with one N28F512 and one NF28F256A. I also have a non working 97 and a non working 95 with similar set ups. Looking at the data sheet for these Flash devices they can be read in circuit. Does that mean I can read the contents from the working devices and then program it to the non working devices without having to de-solder them from the boards. The non working devices get as far as checking the Flash and getting no further to powering up. Suspect the Flash chips have been erased.

content: The simple answer is yes, you can read and write the flash chips via the serial port. I've been playing around with this just out of curiosity and I've made quite a bit of progress.The first thing to point out is that there are 2 versions of the 90 series scopemeters, an early version with pre 5.0 firmware and the keyboard integrated with the digital PCB, and a later model with 5.x firmware and a horrible membrane keyboard. The kernel in the 83C196 ROM is completely different between the 2 versions. I believe I've worked out how to program the early version but the later version uses "Universal Host Mask software V1.0", which is common to other Fluke instruments. If anyone has a command list for this I would love to see it.In order to read the flash chips in the early version you first need to enter the kernel. For a working device you can do this in one of 2 ways:1. press both AC/DC/GROUND keys to enter service mode followed by softkey 3 (labelled EM)2. send EM\rFLUKPHIL\r via the serial port (thanks to harrimansat's MAT/CAL routines for this nugget)You can verify that you are in the kernel by sending the ID command as the scopemeter responds with "Scopemeter 90 family MSK V2.01 ; 02-15-91" instead of the usual ID.From the kernel you have several new commands:EO - exit kernelQF - query flash (sends binary flash contents via the serial port)PF - program flashCF - clear flash?? (I haven't been brave enough to try this yet)For non-working scopemeters the service manual details a way to get into the kernel but I haven't tried it out.I've got as far as being able to dump the flash contents and I've managed to program an unused flash location so I'm sure it's possible to write a reflash program. Now I'd like to work out how to do the same with the post 5.0 versions.

After the seventeenth time of grounding TP217, the ScopeMeter sends an <XON> via theRS-232 interface. Now communication is established, it is possible to reprogram theFlashROMs. For special software contact your nearest FlukeIPhilips Service Center.11.

The Scopemeter will stay in the kernel if the flash is erased or corrupt. It indicates that your processor and serial interface are working. You should be able to restore the code unless there is a fault on the board stopping the flash or RAM from working.

content: G'day mahi,I created those manuals back in 2003 and 2006, so I'm relying on my memory here. I’m no expert at this manual scanning stuff, however, I’ll try to fill you in on what has worked for me. These manuals were my first attempts at scanning paper manuals and converting to PDF files. I had to make do with a cheap parallel port scanner a friend of mine gave me after my old HP SCSI scanner cashed its chips in, although I have to admit, this parallel port piece of junk performed a fair amount of work before it too eventually entered into a state of rigor mortis. I’ve been reluctant to buy another quality unit as I’ve been trying to find a good, not too expensive A3 scanner. The software supplied with that parallel port scanner was so flaky, it barely ran on XP at the time without crashing, even requiring Windows re-starts when it locked up. I must've had the patience of Job to get through both manuals at that time.I used the scanner software to create individual monochrome BMP images with the exception of the colour cover for the 93-95-97 Service Manual, which I'll address later. I did not use "Grey Scale" or whatever the scanner software may call it, instead opting for "Line Art, Black & White or Monochrome," again, whatever your software terms it. These "Line Art" images are considerably smaller than "Grey Scale" ones which will ultimately result in a smaller PDF file after conversion later. The drawback with "Line Art" images is that if your pages have photos or shaded schematics, for example, the shading may come out very light or even very dark, whereas pictures or photos will be pretty poor quality depending on how the shading or photo was originally printed. I scanned the pages at 400 dpi or even 300 dpi to further keep the BMP image relatively small. (I found no discernable difference between 300 and 400 dots per inch with this particular scanner). I also noticed that even "Colour" scanned images ended up being smaller than the "Grey Scale" ones at the same resolution with that parallel port piece of junk. Another plus with "Line Art" scans is the fact that the text on the other side of the page doesn’t show up through the page, particularly with thin pages. I never save the scanned image as a JPG because the file becomes a large PDF file after conversion. I know that sounds odd, however, PDF conversion from a larger BMP file resulted in a smaller PDF file with the method I used - there are exceptions, of course. If you do have colour schematic pages to scan, one option is to save them as colour BMP files, however, choose 256 or even 16 colours to keep the individual file sizes small to allow for smaller PDF files after conversion.I used Adobe Photoshop to edit the individual BMP scans. You’ve probably noticed that there are no binder ring-hole dots on the pages of the manuals as I’ve removed them. It’s relatively quick and simple to remove these or other lines, imperfections and such, straight after each page is scanned, before saving the scanned BMP image through Photoshop as individual PDF files. I then opened the first page with Acrobat 7 and then insert all the pages to make up the manual. Bookmarks were added after the manual was compiled. I performed OCR on the compiled pages and selected "Reduce File Size" in Adobe Acrobat to arrive at a rather small PDF manual at around 10 MBs.Regarding the colour cover of the 93-95-97 Service Manual, the scanned colour BMP image is just over 100 MBs. Directly converting this colour BMP image to PDF with Adobe Acrobat 9 results in a PDF file size of 1.15 MBs. Selecting "Reduce File Size" from the Toolbar Menu results in a file size of 194 KBs, a far cry from the original colour BMP scan of 100+ MBs.There are probably other simpler ways around this whole process, however, I haven’t experimented with them. I tend to get used to doing something a certain way and then sticking with that. Maybe I was taking a "shortcut" by travelling from Chicago to Detroit via Mexico City, but it worked for me at the time. There are other PDF creation programs out there; QuarkXPress is one that comes to mind, however, I’ve had no experience with it, so I can’t tell you anything about it.I hope this helps, kind regards,Tom

Although most of us are technically savvy, I would assume, a good number do not know anything about the Fluke command set. etc. For instance, I have no idea if a specialized application is required to upload the new firmware. There has been mention of a Fluke tool, but when I looked for it, I could not find it anywhere; it really wasn't so 'universal' after all.And there are some other open questions that I know I would like to understand before I embark on this journey. Chief among these is.... Will the current calibration be retained over an update? Although most of our scope probably are way out anyhow (considering that most calibration was probably done 30 years ago), it still is better than nothing.Basically, I'd love to be able to have steps that I can follow where I can feel confident will actually result in a usable F97 and not a brick. Right now I just don't feel confident in that.

If you have acces to a calibrator you can calibrete your scope/multimeter. If not is better dont do it. Anyway you can make a calibration data backup and return scope to original firmware. I have flash a B firmare in non B scope and it works. With the Marrob tools is you can always recover the scope.

At the beginning, I thought that the 92B was capped to 1200 but I could not find any assessment about this and one user  was able to correctly backup the flash.To confirm that the infrared interface is working correctly I used a mirror.Thanks and have a nice holiday "ScopeMeter 92B Series II; V8.60; 96-11-20; English V8.50; Italian V8.50; UHM V1.0"https://www.eevblog.com/forum/testgear/fluke-flash-utilities-for-early-scopemeters/https://www.eevblog.com/forum/testgear/fluke-flash-utilities-for-early-scopemeters/msg3515704/#msg3515704

content: Hi,Try to enter the scope via the terminal at the speed COMx = 1200.Then send the requested speed value to the scope (PC "Program Communication" = 19200).Then enter the terminal and set the same in the terminal COMx = 19200.-This is relevant only in an open session.The next time you turn on the scope, you will have to repeat everything.

content: Thanks asis for the replay.This is exactly what I do using screen or gtkterm withing Linux/OpenBSD. Open the tty/serial at 1200, send "PC 19200\r" (like in the documentation) and then change the baud rate of the serial terminal to 19200. The return code of the PC command must be 0 to be accepted by the scopemeter, other positive integers are errors and I always receive 2 and the baud rate remains fixed to 1200 (status word is 4 = parameter out of range)
