Maknig my own DMM leads.
cdev:
I do that more often than I use the leads mine cane with. I usually use a robust ground clip and grabbers
--- Quote from: DW1961 on July 20, 2020, 10:08:35 pm ---I want to solder and make some of my own DMM leads. I'm not talking about the part that goes into the DMM itself, just bare wire to clamps, things like that.
For instance, if I wanted to use some stranded wire and solder the ends onto some alligator clamps, which clamps should I use (normal tin, Copper, etc.)?
Also, I'm assuming I should also use the silicon sheathing, and not the PVC for flexibility, and what AWG?
Last, generally speaking, I know wire is wire as long as we know what type it is, copper, aluminum, CCA, etc, so can I just use the cheapest pure copper wire I can find, such as "speaker wire," for general hook up needs, something like:
KabelDirekt - Pure Copper Stereo Audio Speaker Wire & Cable - Made in Germany - 16 AWG Gauge - 100 feet - (For Hifi Speakers and Surround Sound Systems, Pure Copper, with polarity markings)

Sure, so long as you keep the leads short and you can tolerate some voltage drop at those currents. Of course your mileage may vary with clip quality, stripping practices, etc.

The leads would only be about max 2' long each.

Can you post a link to what you use?

Recently, one of the cheaper decent DMMs, I think it was an Aneng, was advertised as coming with a nice kit of different probes well suited to getting the most use out of it it seemed. It included both clips and probes.

I just don't trust the cheaper leads is all. I just ordered 120 feet of real copper15AWG silicon wire for 8.50 cents. That should make plenty of whatever leads I need, and I know teh connections will be connected right too.
