How to work with digital multimeter displays? Answered

ive got some old digital multimeters which no longer work. I see their displays lying around and get this urge to make them work and see them showing something (temperature probably?)......
So, well... as you would have found out, I dont know how to do this. I can use microprocessors but how to and where to work them?????
God, i need help with relaxing my brain... ;)


.  First thing I'd do is get model/part numbers from the displays and search for schematics and/or pinouts. You may have to start with a meter model/part number and work from there.

Good idea... lemme try this... ;)
