Coil Inductane - Q Measurement

[Daves]

Hi,
I saw content about coil values (inductance, Q etc.) but I couldn't see any information about how to measure them correctly.

I have wound a coil and want to measure its values. I have a Hantek LCR meter.
Which frequency range should I choose and measure? In LCR meter;
There are options such as 100hz - 1khz - 4khz - 10khz - 40khz. The values change at each frequency.

I think that you should measure the parameters of the inductor coil at the frequency at which it will work in the detector

but the frequency I want is not available in the lcr meter

So you have to choose a frequency that is closer to the operating frequency of the coil.

This is how I measure right now. I wonder if there is a different measurement method?
I'm researching the values of other coils, have you seen such a topic?

Something similar to this?

Here is some background reading on inductors ... and Q factor.

The Q value changes because the inductive inpedance changes ... but the DC resistance does not change.
As your coil will probably have a low resistance, like under 5 Ohms, your meter may not give accurate or consistent readings. An alternative method for measuring low resistances is:
Pass a known current through the test resistor, and use a voltmeter to measure the voltage drop on the resistor. You can then choose a higher current, for example 200 mA, as your test current. This will then give you larger voltages to measure, which will make them more accurate.
