Don't use alkaline batteries. Have the OM-1's modified to use the same
silver oxide batteries you use in your OM-4. One characteristic of
silver oxide batteries that is the same as mercury batteries is that
both maintain their nominal voltage level until near death. That's why
mercury batteries were used in the first place.
Alkaline batteries, however, while still able to deliver a fair current,
begin a significant drop in voltage almost immediately and continue that
drop as the battery is used up.
The accuracy of your meter is dependent on that stable voltage level
from the battery. Throw out any and all alkaline button cells.
