Hello Doug,You said that you bought a capacitance meter, but don't think it will measure at the level you need to. For cable capacitance measurement, for say 1 meter long interconnect cables, you need to be able to measure in the 0 to 100 pF (0 to 0.1 nF) range. Not all meters will go that low.
HAVE FUN,

Maybe I should wait until Doug replies, but he could easily have bought a suitable capacitance meter. I bought one for $79 or so from Fry's Electronics, and it is extremely sensitive in the 1-200 pF range. So much so that one has to consider lead capacitance to get an accurate reading.BK Precision 810B
Well, I bought one from MCM, it's a BK 875B I think or is it A? It seems unclear. The site below refers to it as A, but it looks like B in the picture. MCM says it's a 875B.Not a cheap meter, but I think it will do what I want to do. Won't it? Granted, more expensive than 75.00. Oh well. I am tired of shipping back and forth, if this one does the job, I am keeping it.

Measures capacitance - 0.1pf to 20,000uF with 1% accuracy up to 200uF and 2% after that
Measures inductance - 0.1h to 200H; accuracy 2%
Measures dissipation factor of caps and "Q" of inductor
Measures resistance - 1 milli ohm to 20M ohms
3-1/2 digit LCD
Low battery and overload indicator.Since I was told an LCR was the way to go, I chose this over the lesser expensive capacitance meter.
CableLex, you still won't easly measure inductance with this meter. It doesn't go low enough. I have one like it, myself.
Thanks John. I can measure capacitance though, right?From what was said earlier, I felt measuring inductance was likely out of budget at this time. So, what is the least expensive way to measure inductance? Well, is there an affordable way?
