[Boatanchors] ohm meters

[Ian Wilson]

I have had a couple of RadioShack (Micronta) digital meters.
One of them was quite calm when measuring reactive components.
The one I have now (the other died after more than 10 years of
service) exhibits the behavior you describe when measuring things
like chokes. Circuits containing electrolytics and high impedance
circuits also cause it to hunt but it usually gets there in the end.

On these 2 data points, I would guess that it depends on the make
and model.
