Owen, are you trying to pull a Cecil or Art by changing the subject of
the thread? If you recall, this thread was about identifying an
unknown ferrite core. For that purpose *any instrument* capable of
measuring Zmag less than 200 ohms will work fine - even one that is
restricted to less than 100 ohms.

A fair point Danny.

I did provide some specific information on the core if you read back
through the posts, probably more than any others!

But I still stand by my statement about the limitations of the '259B in
assessing inductors as qualified.

I 'm not defending the 259 as I use something else here that can
measure impedances greater that 20K, but that high range servers no
purpose if I am looking a impedances less than 100 ohms.

I envy you, seems we always need (want?) to measure something that is
beyond the range of the instrument conveniently to hand.
