Has anyone ever undertaken the task of adding a diode between the battery and the meter cell to reduce the voltage from silver oxide down to old mercury cell standards? I need to drop 4.5v PX25 down to 3.9v in this new Elmo C300 of mine. I've thought about making a button cell cradle with the diode built in as a battery adapter but would rather take care of the whole problem from the start and just do the thing the right way.
I'm assuming (probably wrongfully so) that if I get the voltage to 3.9v I won't have to recalibrate the meter. If so, this project is going to take a lot longer than expected.
