Avometer model 40
Hi I was out for my once a day exercise and came across a avometer model 40 I dont no anything about these I checked the batteries and changed the 1.5 aa then checked the voltage of a battery and a resistor on the meter seemed to work
I know nothing about them or how to use one. Would anyone have a manual for it so I can find out more and learn how to use it properly and find out about the q
