content: Hi gang, does anybody have come across a mutimeter for electronics thats not industrial like Fluke etc but something like chinese clones but not a complete trash that has the following functionality.live(or slightly delayed) data graph for voltage and resistancesUses 3v to measure diodeuses 2v to measure resistancecan read as low as 0.01 ohmand is decent overall ?I work on laptops and computer graphics cards. my cheap chinese multimeter works great but it cannot measure low resistances and it does not have any graph data at all.Any recommendations ?I currently own fluke 289 and i dont like it. it gives me strange resistances in specific areas and it does not have live graph, only recording and playback.Thanks

content: ANENG AN870, AN8009 and Zoyi ZT-Y go down to 0.01 ohms very accurately, and use 3.2V for the voltage output. All of these are around $20-$30 at AE.The ZT-5566 is a slightly better ZT-Y. It's a benchtop with bluetooth speaker, so you'll pay a few times more than the others.Not sure why you need to consider the resistance voltage? The meters I mentioned are roughly 0.4 mA output current (when tested using another multimeter in its mA current range). If this is something you really need to know, say something and I will test them using your sample resistor size.What are you expecting for graphing exactly? An oscilloscope? Historical Tracking? Just a bar graph on the display?BTW do you need a thermal camera for your troubleshooting? The Tooltop ET13s IR+DMM does voltage graphing historically on screen in the multimeter mode. However this meter has poor low resistance performance. Not to be trusted under 10 ohms (that bad). On the good side, the diode output voltage is nearly 4V.

content: Good Morning Tonycstech, My vote is for the EEVBLOG 121GW. It can meet your requirements and has features you won't find in most DMMs. Some claim the readings are slow, but it's an easy work around. My favorite feature is the 'reverse continuity' mode,which is great for finding intermittent breaks in continuity, as it beeps on break. You will never regret having this DMM in your arsenal.

content: If I was looking for accurate values below 10 ohms, I would go with a milliohmmeter as well. However, of you are looking for a multimeter which has a resolution to 0.01 for identification purposes only, the ones I suggested are fine. However you may need to activate the REL feature to remove the test lead resistance. The ZT-Y has a REL that covers most of the features the multimeter does.

content: The issues is all the same across premium or bench top meters.Too much current/voltage measuring resistance.Need less. Need to be able to adjust that with the firmware.That will fix the "none existent" problem.While many of you engineers can argue about my lack of knowledge how electronics work (which i will not deny i have no clue how they work) it all comes down to one problem which is:99.9% of all meters on this planet will measure 1.2K while 0.1% will measure 300ohms or if leads are reversed, 2.5k but no where near 1.2k.With that said, it is absolutely pointless to argue with 0.1% of earths population who are engineers because they are simply too smart to understand stupid problems that idiots like me bring up from time to time.Case closed.Solution: NoneConclusion: Junk equipment is much more reliable when it comes to fixing high end electronics than high tech/high price equipment cant. I have nearly 100% success rate behind this statement.

No need to hunt excessively for a special DMM.I've also proven previously that even the cheapest power supply and DMM can very precisely measure low resistances using the Kelvin sensing method.Test Controller can perform math functions on multiple inputs, so you could have an Ohms display based on V/I:https://www.eevblog.com/forum/testgear/program-that-can-log-from-many-multimeters/

content: Quote from: tonycstech on September 30, 2024, 07:18:24 pmMy guess is that you are trying to measure in-circuit then. In that case you need to understand that all chips have transistors, MOSFETs, ESD diodes (=semiconductors) in them which cause resistance readings to depend on the measurement direction and measurement current. There is no fixed input resistance when semiconductors are involved. IMHO this is a good thing. I have used this property to find failed chips on numerous occasions by measuring resistance in both polarities and between ground and pin and supply and pin. On pins with similar functions you should measure similar resistance values when measured using the same polarity.I think looking for a DMM with a limited open voltage is a good thing as modern semiconductors can easely be damaged by high voltages. Unfortunately many DMMs have rather high open voltages like 8V which is way too much. I like the Vichy 8145 bench DMM I have for that reason, it measures diodes using 3.3V which is generally speaking safe.

content: He’s asking what value you want to measure. And probably why.Other than identifying a gross short circuit on a power rail, its resistance is meaningless.It isn’t clear to me (and likely everyone else here) what it is you’re trying to accomplish. Like, what is it you think you learn from a resistance measurement of a circuit with non-ohmic components? (I am not asking this to be sarcastic or rhetorical, I am genuinely curious as to what insight you gain, or wish to gain, from such a measurement.)Correct me if I’m wrong, but I think you think that the numbers you get are in some way inherently meaningful. But they aren’t. The only thing you can do with them is compare them to other numbers from a similar meter. That is because the numbers are only “true” within the exact test conditions created by that meter. A meter that creates different test conditions will create totally different numbers with an active circuit. Neither one is more or less correct than the other, because they’re both specious.Testing in-circuit is always fraught with peril. You really need to know what you’re doing so you can know which results are valid and which aren’t — and when you have no choice but to remove a component from the circuit to measure it. Just today, I desoldered a few resistor networks and a transformer from a board in order to determine the resistor networks’ topology and the transformer specs. No way to do it in-circuit.

After doing so many of these i can tell what the problem is just by looking at the value.Testing in circuit is always.......?yeah, except that when i get the same reading using anything buyt FLUKE and bench meters, begs the question. Why not design your meter to get the same reading ?Other than that, FLUKE replied to me saying they "do not offer" firmware modifications.My argument is simple. 99% of all meters will give me one value while 1% will give me another.its a simple majority rule.I do not agree with the democracy in this regard because majority could be a bunch of idiots and there has to be a balance so the balance is: let me adjust voltage/current of the meter so i can get the same reading as other meters get.But we all know thats not going to happen so there is no point to continue this topic.Someone please lock it.

content: Quote from: tonycstech on September 30, 2024, 09:23:42 pmThat is not going to happen due to differences in measurement currents and how the multimeters are constructed internally. The open voltage on various meters is different and some meters may have a true current source while others may have a simple series resistor to limit the measurement current (depending on range). Both methods will yield valid results when a true resistor is connected to the meter. However, when measuring in-circuit with semiconductors involved, you will get different readings between meters.

content: Quote from: tonycstech on September 30, 2024, 09:23:42 pmYikes. That's inherently flawed thinking. As others have said, those readings are meaningless.The only time your in-circuit measurements have meaning is if you're comparing a known good DUT vs a faulty DUT (both identical circuits), under the same measuring circumstances. Then you can compare the values and ponder why the discrepancies. Without that specific comparison, you would need a schematic with in-circuit values for every device, and that doesn't usually exist.Altering a DMM as you suggested is called adjustment. Adjustments are made with a calibrated machine, usually specifically made for this purpose. Arbitrarily adjusting a DMM based on irrelevant noise will only guaranty degrading your DMM.

content: The graphics cards are going to have similar operating principles and similar PCB layouts. So obviously you are going to learn what to look for, even if your method is flawed from a technical standpoint. It's fine to go that route if you've got work to do. But from a "right" and "wrong" perspective, you're just flat out wrong and the more you double-down on your position, the more foolish you look unfortunately.You already know how to inject voltage into various parts of the circuit to look for shorted components. The same principle applies with my suggestion to use a bench power supply set for the values you want.

content: Correct my theory if am wrong (am sure i am)A: multimeter uses 2v to measure resistance and gets 300ohms because parts of the circuit it measures gets enough current from those 2v to actually do something with it, such as pass it alone down the line or the other way around. This make sense considering typical voltage any transistor gates is anywhere from 1-3v and the fact that there are semi conductors just complicates this process even more.B: multimeter uses 0.5v to measure resistance and gets 1.2k because none of the parts of a circuit get enough current to do anything with the 0.5v and therefore resisting the current flow much less giving you higher value in Kohm range.Thats what i think is happening here.For that reason, i want to lower the voltage and limit the current to get the same results of a chinese meter.Cant do it. No one can. Whats the point of this conversation ? No point.

content: I don't know if this will work for your measurement or not, but the OLD Beckman Tech 3XX meters (Tech 310,320,330) have a very low in circuit voltage of only 200mV when measuring resistance. It's an oldie but a goodie, and its the lowest voltage I've ever seen on a multimeter. The meter is not auto-ranging like today's multimeters (Fluke or otherwise), but its a low enough voltage it won't turn on silicon junctions.

As I said previously, you need to know the correct tools for the job, and how to use them, rather than trying to force an apple to be an orange.The R (in LCR) stands for Resistance, and the ST42 can do Rs, Rp, Z, ESR, and Rdc. The ST42 voltage is rated at maximum 1Vpp, which means about 350mVrms. Test frequencies from 100Hz to 10kHz.ETA: Since what you really need is an LCR, if you also need graphing, you'll need to spend more. Either a bench LCR with ethernet, or a HH LCR with BT. But you can also use some LCRs with TestController software, which will allow all sorts of graphing.

content: Hello tonycstech.The UT181 will put a max compliance voltage of 1.2in the kOhm rangeand upwards, below that is 3.3V. The graphing is not live though, you have to record and then plot, unless you use the included IR interface.The Metrix MTX 3282 (and I guess the rest of the series) has an around 1.2V max compliance voltage, which drops pretty quickly. It is discontinued, and a bit quirky in a few regards, but you might find one second hand. It does live graphing.2N3055 recommended, in the third reply, a currently produced model. Also has live graphing but it is quite expensive.Also, the Ohms function in DMMs is designed to work with ohmic circuits, and intends to give results relative to Ohm's law. If you are using it for a different purpose and it doesn't work, it doesn't mean there is a design flaw, or that the meter is crap, you are just using it for a different purpose. The fact that some of them work is just a nice bonus with some DMMs. That's why you are getting flak.I think what you are trying to measure is a circuit signature (not sure about that name). There are expensive curve tracers for automated test setups, which compare the traces of products with a known good sample in the production line.In this case, that is kind of what you are doing, identifying problems with controlled test conditions by comparing with a known good sample. You might be able to use the ohms function, but the tool for this is not necessarily an ohm meter.You might be better off modifying one of the "shorty" circuits, or using an Analog Discovery.EDIT: The diode test voltage of both the Metrix and the UT181A is ~3.1V.

Even in auto mode it will determine what parameter you are measuring and provide a value 3 times faster than the Brymen 786, which is already switched to the correct mode (Ω for instance).I love a 6.5 digit meter with 0.01% accuracy on ohms as much as the next guy, but repair work is not like R & D or experimentation. Insane accuracy is not key. You are mostly trying to see if a component has failed rather than whether a 1% resistor is 0.01% out of tolerance.Also, try not to cherry pick or use lies of omission when you're denigrating something. That's an untrustworthy politician's move because he thinks no one will fact check him (see Donny Trump as an example). That 1.5% tolerance you tried to pass of as the entire story is only for the 99.99MΩ range. Everywhere else in Ω it is 0.5% which is fine for an inexpensive meter like this.

content: It says right here that the 1.5% is for the entire Ohm range:https://www.toolworld.in/storage/media/product/technical_documents/DMT-99%20Multimeter.pdfSince most circuits use 1% resistors nowadays, I'd like to have a meter with more accuracy than the components which isn't hard to achieve. I do hope you agree with the fact the DMT-99 is showing way too much digits versus its accuracy. I hope you also see that measuring 0.01 Ohm is not going to happen with a relatively simple, 2 wire DMM. Heck, most 6.5 digit DMMs will have trouble doing that even though these typically have 4 wire connections. Your best bet for measuring low resistance values is likely the Keithley DMM6500 which has a 1 Ohm range versus the usual >= 200 Ohm range being the lowest range for resistance measurements on DMMs.

I had misread the specification earlier .. so RFTMproperly. My bad on that one. I'll correct the offending post.Comparing this to Keithley is like bringing tank to a snowball fight.Anyway, I know everyone has a hate-on for older meters but my Fluke 8012A is a 2-wire meter with a 2Ω range.
