content: I've been looking around at used Fluke Multimeters on eBay.I found a Fluke that's labeled "Fluke 87 True RMS Mulitimeter". Is this a first generation 87 and not a Series II, III, IV or V?Some Fluke 87s are labeled 87-3, 87 III, 87 IV, 87V, etc. I'm uncertain about 87-II?So if the front label shows only "87" means it's a 87-I or first generation?I'm not really certain differences in the generations such as Series II, III, IV, V, etc. Is there some sort of documentation the help to determine differences?

It's a good meter but it's definitely not an 87V.

content: Quote from: 001 on December 18, 2018, 12:00:35 pmEarly 87III's had green backlights - they switched to white somewhere mid production. I have one with the white LED backlight, and three with the green type.The 87III does do high res but it re-boots the meter to put it in that mode, and it's very slow in hi-res mode, 1 update per second if I recall. The 87V is much more usable for this.I saw somewhere (maybe on this forum) the white LED models were the unofficial "II" version, with improved CAT ratings. TBH I haven't even looked at mine to confirm.

content: I've been using a 75 for quite a while just around the home mostly to test voltages, resistance and continuity.The piezo buzzer problem with the 75 is in another post where where people have offered solutions.https://www.eevblog.com/forum/repair/fluke-75-piezo-buzzer-repair/msg2035393/#msg2035393Anyway I picked up a Fluke 79 Series III (true rms) to replace the 75 (once repaired will be used as a spare)However after reviewing prices and options I came across a Fluke 87 (first generation without leads) for less than I paid for the Fluke 79. ($110.00 with shipping)I was just wondering about the features of the Fluke 87 first generation compared to earlier models such as the Fluke 79 and later generations Fluke 87 III, IV and V.I'm uncertain if I need the features of the 87 when compared to the 79, as I only use a DMM around the home and testing circuits in automobiles. Perhaps could use a more advanced DMM but am uncertain.

content: I don't know I could try and put the 79 for sale or have three Flukes.Years ago I use to repair some types of electronics, use to have a small lab with a couple of 250 - 350Mzh Oscilloscopes, other meters and test equipment, but currently only repair electronics once in a while when the need arises, such as with automotive electronics, etc. and use to play with transistor logic boards, devices, etc. but haven't for quite sometime. I'm uncertain if the need would arise or not.I still have an old 10Mhz oscilloscope in storage.Perhaps I'll take a look at some other Flukes such as the 289. I see there is a new 289 with leads and probes eBay for US $164.99. Is that a good price for a 289? I haven't looked at all it's features and see it requires USB IR using a Fluke IR189USB cable.Is there Fluke software that works with the 289? What are the advantages if any connecting to a PC?

content: The cable and software are only needed if you are going to connect it to a PC and log. $164 is an excellent price for a Fluke 289. There is a great thread on EEvblog if you do a quick search describing the highs and lows (pros and cons) of this meter. It's very good, but not perfect. Check that out first.Good luck!

content: Quote from: albert001 on December 18, 2018, 10:13:12 pmThe LCD had issues on the 87 (Zebra strips), fluke still sells a kit to fix the problem. There was at one stage an official back light upgrade kit for the 87 (white) - mines still the original green back light. Also the rotary switch could be a problem on the 87. It would wear also the contacts needed frequent cleaning. Finally, they pre-date the CAT rating if that is important to you.It was a good meter thou, but after I repaired mine a few years ago, I put it in a draw somewhere and bought a new 87V.

And im not personally impressed by all the 289 fuss, tried one 1 month and returned it, i dont need over complicated meters lollBut it will always depend on your needs, precision, data logging features ?? and all the other acessories you may need to buy ?

content: @ electro dont forget the super capacitor issue in 189 and 289Have ordered 5 battery clips kit from fluke usa, yeah 5x kits lots of $$, and got 5x supercaps at 1.60$ each, changed the 3 in my 189's, they were oxydized, one has begun to drain the battery. Changed 1 battery clips kit.If your patient you can snatch very good meters on the web.Took me a while to get my 189's and the extended battery packs bp-189, they dont cost a fortune to calibrateand i love the fact you dont have to always open the case for the fuses and battery replacement.The 8x series at my job had battery had clips changed, some dial switch problems (resolved with an good cleaning), damaged thread screws (opened too often for fuses change and battery change)Even had an Mastech 20,000 count ms8340 first generation who had the 2 hrc fuses in the battery compartment, made an error to re-sell it, the newest ones have only 1 hrc fuse.

content: Quote from: Fungus on December 19, 2018, 08:22:21 amYes that's probably true a Fluke 101 or similar should work most of the time for basic testing voltages, continuity and resistance. I use to be more into electronic repair using various types of electronics test equipment such as oscilloscopes, bench meters, etc. I still have an old 10Mhz oscilloscope in storage and a few test probes and leads.I'm not really certain if I need something with more features for around the home and working on automobiles. I have some older automobiles with more sophisticated electronics. E.g. I'm trying to repair a VIC (vehicle information center) module that has problems as it ages of the circuit boards developing micro cracks I'm told due to the manufacture used lead free solder it's two circuit boards tends to develop micro cracks over time. Solution is to re-solder the boards and replace any bad caps.I have an option to return the Fluke 79 that's suppose to arrive this Friday. I can just refuse the shipment and it will be returned to sender.

There is one that's suppose to be new on eBay for $380.00 or best offer.The 79 even though the eBay seller has a 14 day return policy, won't accept a return unless the meter is doa or somethings not working.Stated the reason is he has to pay for a warehouse and people to package his items. Also I paid $20.00 for shipping which isn't refundable.So if unable to return the 79 and it wouldn't make any sense to purchase a 101 if having a 79 III to use.Hasn't arrive yet.

I hear crickets chirping...) documented the CORRECT way to do it with a long term parts replacement, I'd have it done yesterday.i.e. in this case I adhere to "don't fix it if it ain't totally broke...yet"Anyways, both meters work great and agree on the displays, so I let sleeping dogs and supercrapacitors lie for nowGood luck with your parts swap ordeal.

content: This is topical for me. My only two meters just happen to be an 87V and a 289. I like them both, but if I was buying a single meter, I would 100% go with the 87V. The 289 is feature rich, but I rarely have use for the logging (and would probably use my scope anyways) and the drawbacks outweigh those features for me. It is massive, heavy, sucks down batteries, and is fragile compared to the 87 (look up the IR diode issue). If you think you will use the added features or just want the fancier of the two, the go with the 289. If you are looking for a rock solid meter you can probably run over with a car, that is easy to use and not overly complex, go with the 87V.

content: I found a 87 V for $150.00For the 79 III I tried to get the seller to issue a refund and he messaged that couldn't issue a refund based on "Change my Mind" I then asked him about a partial refund and would only offer a $40.00 refund.He also said he has a different address for returns, so if he sticks to that I would need to pay for return shipping instead of refusing delivery. If you refuse USPS deliveries and the package hasn't been open USPS will send a package back to the return address at no cost.He had it listed with a 14 day return policy without any conditions such as only if DOA, not as described, so I'm going to let eBay decide. eBay's fairly good at handling returns and getting sellers to issue refunds.If not able to get a full refund minis the $20.00 for shipping I'll probably keep the 79 III or put it up for auction.Here's a link to the 87 V I got for $150.00, (best offer accepted) appears to be in good condition.https://www.ebay.com/itm/332966922166

It does not feel right that the seller lost sales opportunity, and incurs a cost just because you changed your mind AFTER they shipped.

So far has offered me a $40.00 then $60.00 partial refund. The 79 III cost me a total of ~$110.00 with shipping. I'm going to let eBay deal with the return of which I believe they will ask him to refund the full amount minus the $20.00 paid for shipping.If unable to get a full refund will either keep the 79 III as a spare DMM or put it up for auction on eBay to see if able to recoup some of my cost.I've been member as buyer and seller on eBay since the 1990s and still have 100 percent feedback as I've never stiff anyone and have always bent backwards to satisfy buyers. I honor any 14+ days return policy no matter the reason why a person wants to return an item.As a seller, If I don't want a buyer returning an item I then either auction an item as-is (no returns) or include a condition that an item can be returned only if DOA or not as described.

content: I'll probably need to clean up both meters some. The internals of the 79 are really clean but the yellow rubber is dirty. From what I read online Fluke rubber protectors can be cleaned with a hand cleaner.The 87 V hasn't arrived. I ordered a FLUKE H80-E rubber protector as it didn't come with one, plus an afermarket hard case to store it in.As suggested I'll take a look at the input sockets of both meters. You're saying to clean them with some contact cleaner with lubricants? All I have on had is the CRC contact cleaner, which should have some lubrication.The 79 so far is working perfectly. I'm thinking of just keeping it for general all around use, putting less wear on the 87 V. I'm uncertain of the leads that came it, they have push clips with soldered on banana jacks. The neg lead needs to be re-soldered.I have some other test leads. A pair of Fluke 1000V Cat III 600V Cat III, the banana jacks are concealed and 90 degrees. I also have an pair of Agilent 1000V in storage only used a few time the jacks are also concealed and straight. An older set of leads that are braided, with alligator clips I'm not certain what decade these are from I don't think you can find them new any more. Haven't seen them around. There more flexible than the more modern rubber leads.And another set included with the Fluke 87 V.Also found a Blue Point EETA502A AC/DC Clamp Adapter

content: I think I'm going to just cancel (close) the return.Since I first wrote to the seller about a return before initiating a return. It's unclear whether the return is a full refund or $60.00.When I started a return I was already communicating about a refund or partial refund and he wrote back saying he would refund $60.00.So the refund amount is unclear. My phone doesn't work at my location to telephone eBay and there's no ebay contact or ask eBay to step in link from the return details.I never did ask eBay to step in so I suspect the refund amount would be what the seller stated in ebay messaging.I wrote to the seller about it but haven't heard back and I'm tired of messing with the whole thing.I've never had this problem in the past when contacting the seller befor initating a return.So in the future if needing to return an e-bay item will first initiate the refund before communicating with the seller.Imo it's a good quality dmm without alot of features, more for general all around use. There's many things you can do with a 79 III.I can use it as a backup or to test other multi-meters. For general use it will take some wear off the 87-V.

What so many here fail to realize is that "the best" depends on what you do with it. Each has a price and function benefit or it would not be on the market. The post you respond to directly addressed this point of different tasks for different meters.For casual hobby use, almost any meter is fine. In fact, low cost is good if you are not used to electronic work. If you wreck it then there are fewer tears.

content: Hi,I own an 189 for a long time and it work all the time very good.Last year bought an Brymen BM-869s and from few week ago an Agilent U1253b.Still like to use the 189 but currently the most I use is the BM869 and the U1253b.The brymen is fast as one more digit and very important to me, as I became holder, the display digits are bigger.Also records the last switch mode, i.e. if the last I was checking for continuity, when switch on next time, he will in continuity mode.The Agilent is good for dark spaces were the oled makes the difference.As I said previously I still like the 189 as he works very well with components under RF.Rodrigo

content: Partially because the return is ambiguous and other reasons I decided to cancel the return and keep the Fluke 79 III.I think it's good enough for most automotive and around the house repair and diagnostic work.I noticed some of the specifications of the Fluke 77 IV exceed the 79 III. The Fluke 77 IV has min/max and range buttons is 6000 count vs 79 III 4000 count.I haven't been able to find a user or service manual for the Fluke 79 III. There is a service manual for the Fluke 79 series II but no series III can be found.
