MINOLTA AUTO METER III Light Meter REF Finder

MINOLTA AUTO METER III Light Meter

With REF Finder

I received this from a friend knowledgeable about cameras a while ago, but I ended up not using it and kept it in storage.
I'm letting it go as part of decluttering.

The LCD screen has some cloudiness, but
the power turns on with batteries inserted and the display is fine.
I have confirmed that all switches are working.
Measurement was also possible.
I have forgotten the detailed usage instructions.

Please check the images for the exterior condition.
Lightly cleaned.
Batteries are not included.
*Requires 1 AA battery.

Thank you for your consideration.
