I have several analog meters and they all use two AA batteries. Except
for the one mini meter which only has only one AA battery.

The Simpson 260 VOM used a single D cells and a 15V battery (Eveready
417) for the Rx10K range. Later models switched to a 9V battery and
then to 4ea AA batteries. The Triplett 630 used a single D cell and a
30V (Eveready 413).
