Why do LCR manufacturers give the details of measurement frequency to us?
$begingroup$
When you want to purchase a DMM, more probably you don't see at what frequency the DMM you considered would work BUT in the situation you're considering to purchase an LCR meter, manufacturers give you big details on the frequency of the LCR meter. Several question?
- Why do they give us the details on the frequency of their LCR meter?
- It seems that they gives us measurement frequency for all of three components. Resistors, inductors, capacitors. Okay, but how to choose the best frequency for each one of these components?
Here is several links to some LCR manufacturers:
IET/QuadTech 7600 Plus Precision LCR Meter
Lutron LCR-9184
HIOKI IM3536
CEM DT-9935
MS5308

They give you the details because for real-world components there isn't one concrete value, they are all dependant on operating frequency to a greater or lesser extent.
The best frequency will depend on your application. Ideally it would be the same as your target operating frequency.
For example, if you are measuring an SMPS inductor then a high frequency will be more useful (as your circuit operating frequency is likely to be high), an electrolytic capacitor would be best measured at a lower frequency (as they don't have, and you wouldn't design expecting them to have, good high-frequency performance) and a line-frequency choke would be best measured even lower.

If we consider a real inductor there are several factors take into consideration.
The windings have resistance
There is capacitance between turns
The permeability of the core is frequency dependant.
As such trying to produce a single figure for inductance is difficult and the result will vary depending on the measurement frequency.
Similar arguments exist for why a capacitor or resistor is frequency dependant too.
Since the answer varies with frequency the manufacturer has to tell you the test frequency.
