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.
