[Heath] Info on Heath IM-25 solid state VOM needed

[Mark Johnson]

I've had a couple of those meters...the  manual says to keep them away from RF and I can verify they do not do well with RF. I mistakenly fed RF into my first one and that was the end of it.

Like any old meter, the calibration will be suspect given the divider resistors will more than likely have drifted off spec.

I do have one on my bench now and use it for doing alignments etc. Neat old meter. Oh and the battery needed for the ohm meter is a bit of a challenge to obtain......

It appears to be a complex piece of measuring equipment. Is it dependable or is it a maintenance problem? It is a nice looking meter and I hope it is as good as it looks. Thanks for any information you can supply. 73, John, K5PGW
