On the Honeywell Pentax 1/21 spot meter, the one with the little round button on the side of the handle.....
I know thats the scale illumination button but does the oddball 1.3v battery light up the view finder scale?

So far I only have a 9 volt in it and that doesn't seem to make the scale light up.

I did search around for some information and so far I have not come across anything helpful.
