But when measuring iron-cored coils, remember the inductance you see depends on the frequency and voltage you use to measure it, so you can get any answer you want.
I tried to warn him of that!

I suppose, but it ought to give me a ballpark figure. I don't have the money to buy an expensive LC meter...

Even the expensive ones are iffy, but mostly a good measurement is all i need, not a perfect one.

Does this apply to ferrite cores as well?

I worked in a coil winding factory for a bit (I've mentioned it elsewhere) and we used an inductance meter for checking all the coils (mostly ferrite cored).

Yes, for ferrite cores without air gaps, although they're not so bad as iron. An air gap makes both kinds much more linear.

For production testing it doesn't matter anyway, as long as you use the same measuring device every time, you'll get answers that can be compared.
