Good day fellow APUGGERS!
I have a fairly straightforward question. I just picked up a perfect condition Vivitar 43 exposure meter for a song. There are no instructions with it, but I don't really have a problem with the operation per se. My question is about the battery.

The meter has an A76 LR44 battery. Does anyone know if the LR44 is the proper battery, or should it take an SR44 instead? There is nothing inside the battery compartment or on the case which indicates.
Secondly, there is a 'battery check' function on the meter. I figured out how to conduct a battery check, but what is unclear is exactly where the needle ought to point. Can anyone help me on this?
