Could it be that the meter was calibrated to compensate for the fact
that when it's hooked to a battery, it only supplies current when the
charger exceeds the battery's voltage, while on a lamp it would draw
current from zero on up?


No.

Also comes to mind that if there is a magnetic pointer restraint this
is unusual, and perhaps the meter would (as usual) have bal;ance
weights to restore to zero, so perhaps it is calibrated for when the
meter face is vertical (panel mount style)? A moving iron movement
responds to RMS so waveform should not be a problem.

FWIW I just went down and tried an orientation test with the meter
reading 5 amps and the pointer stayed in the same position whichever way
I tipped the unit.
