Subject: L & C measurements cheaply, how?
I am curious how most of you are measuring L & C's for homemade tesla
components. I am looking for an inexpensive way. At school I had DMMs,
scopes, function generators, FFT analyzers, the works, ... but now that I
have graduated and gone home, and it is painfully obvious that I lack
even the basic tools. I don't even have a digital voltmeter. I went
looking through the catalogs I have here, and found only one inexpensive
DMM that has inductance measurements: the wavetek 27XT. This unit seems
to be able to handle the ranges necessary for Tesla coil parts, is
anybody using this for measuring homemade components?
I have tried using my cheap rat-shack analog voltmeter and 120VAC 60Hz to
measure my cap & choke values, but the voltmeter impedance is way too
low, and it's highly parasitic. Plus, it doesn't even zero properly.
Someday, I'll save up for a scope & func. generator, but now I just need
something cheap and convenient.
Thanks,
-Adam
