Default Re: Reading anomaly on old Philips DMM.

There's also offset voltage in amplifiers and comparators, and one that's not so well known: bias current flowing in imbalanced impedance presented to both inputs of an amplifier/comparator. There may be trimmers for some of these. I don't know that meter specifically.
