TBF a meter with REL might be nice for such measurements. Zoyi also make a ZT303 which as 20,000 counts and REL. There are many projects on youtube that make a current source. If you supply 10mA or 100mA with leads, you can use any multimeter in millivolts mode to also read the resistance value, by ohm's law. If you want to do things very cheap. But a self contained unit such that you demonstrate is nice to have.

Zt303 is very good for diy milliohm tests.

Have you tried making finer tip probes .. The probe clips are too thick for smd
@RolandW_DIYEnergyandMore2 ай бұрын
well, I didn't change anything as those clips worked for me. I don't clip onto the components, just touch them with the edge of the clip. But I think it would be possible to even maybe solder a very short tip between the 2 fingers. Just keep the injector side and probe side near to the point of measurement.

I have the YR1030+ to measure internal resistance of batteries and other low resistances (cost me 550Baht) I thought you have it too? Is there any difference?
@RolandW_DIYEnergyandMore6 ай бұрын
Sorry. I have just tried out the battery meter and it works as well. I have failed to do it before, as it is very tricky with those spring loaded probes to work on components or PCB pins as the tips are to far apart. I just saw that there are offers with other probes included as well which I don't have. So yeah, you are correct :)

That device is using AC signal to measure devices I suspect, whereas this one uses DC current. Both methods can work for single resistors

My 9.99 euro multimeter has capability to measure max 2ohms in 1milkiohms resolution... Is it bad? It can change resolution to 100 milliohms and then the max is also 20 ohms I always have a feeling my cheap multimeter lies and is not precise, too many function for such low price, this new way with 4 wires is cool cause it removes the probe noise\error
@RolandW_DIYEnergyandMore6 ай бұрын
measuring values well below 1 ohm with 2 wire methode will return inevitable faulse measurements. For the 10 euros you have most certainly got the "all in one - wonder" Meter. Nothing wrong with a cheap meters, its just some features might be just out of the marketing booklet only so you should always double check. find a low value shunt resistor on a board, read the value which is written on it and make a measurement. Then just see what the meter claims ;)

You used the word precise saying it is not precise. Don't confuse precision with accuracy. Your meter may have precision but not be accurate. And I would suggest this is the case. What use is a meter that has high precision but have low accuracy?
