Larry, the panel meter is a no name digital meter. I would rather
take calibration service money and put it towards a battery monitor
system like a link 1000, although I have gotten by without such so
far. Thanks for the info nonetheless.

I bet there's a little tiny pot in that kind of meter to calibrate it.
Probably has some fingernail polish holding it fast. Put a known
CALIBRATED meter across the terminals on the back and just adjust the pot
until it reads the same 13.8327 volts the calibrated meter reads.

DVM's aren't rocket science.

Shhhh...don't tell anyone, though. I made quite a comfortable living off
them for many years.....(c;
