Hi,
I'm just wondering why LCR meters often offer different frequencies for measuring inductance? I've used modelswith different frequencies (eg. 100Hz + 1000Hz) but have just bought a cheap model with a fixed frequency of 175Hz. It does have a wide range though.
I realise using different test frequencies gives different results, but why? I assume the meter works using the principle of Z=jwL, or is there something more complex going on?
Either way, when do you knwo which value to take when you have tested with more than one frequency?
