Also, I should mention that the Calibration Refresh procedure succeeds.
I'd expect that if the EAROM had failed or become marginal, the
Calibration Refresh would fail (as I recall, the manual says something to
this effect though I don't have mine here to check).
Thanks,
Phil.

As per Philip's original post, _all_ AC ranges drop gradually. This is really
not consistent with a faulty
EAROM.

Dave,
Thats the question. It depends on the quality of the cells where the AC
calibration info is stored.
I'm not aware of a checksum function on these EAROM's.
If it is the AC part, I've some spare parts if necessary... Just let me
know.
Kind regards, Wim.

I don't think that is likely, as Phil clearly says that all the DC ranges
are correct, it is just the AC ranges that are a problem. If the EAROMs
were bad, you'd lose all the calibration constants.

Phil,
I suspect it to be the EAROM(s) IC 105/6 of this meter. Losing its
calibration constants.
