OK. So I rolled the dice on getting a cheap-o LCR meter. It's a model 4070 that can be found on eBay and other places. It's a neat little meter, but the ranges for inductance go from 20H down to 20mH. 20H. Really? When was the last time you worked with a 20H inductor. A lot of the stuff I'm doing now use inductors from 1uH (TI TPS63020, 2.4 MHz) to a few mHs.
So... 2 questions.
1 - Is there a decent LCR/RLC meter out there that can measure down to the uH range that won't break the bank.
2 - How does an LCR meter work? I could maybe change some component values to change the range from 20H - 20mH to 20mH - 20uH.
I figured I'd ask here first.
EDIT: The test frequency is 100Hz. If I could change the test frequency, to 1000Hz or 10,000Hz would that make a measured inductor appear larger or smaller? Could I get a 1 micro-Henry inductor to appear as though it were a 1 milli-Henry inductor? Thus lowering the overall range?
