[SOLVED] What test voltage should I use to measure an inductor with an LCR meter?

[parachutes30]

What test voltage should I use to measure a inductor with a LCR meter?

What test voltage should I use to get L value of a specified 100uH/2A power inductor? 0.3V or 1V?
How test voltage can influence the result?
Manufacturer specifies L value at 100KHz.

Hi,

Manufacturer specifies L value at 100KHz.

The manufacturer will also specify the measurement current.
Then it´s easy to calculate XL and with this you can calculate V.

If you are measuring with LCR meter
Supplier specified inductance value, test frequency and biasing current. normally the test voltage do not have major roll, Test voltage at 0.1V is the best practice
