Today a Teardown again, long time not made one :-), but additionally to the Teardown I tell some Stories from the 80's when I was Working at AEG in the Industrial Process Electronics Division and used similar but much more costly and Primitive Process Calibrators, Totally different Times, Pioneering Times in so many ways. My Blabla is far to long, skip if not interested :-) Further I reverse Engineered the DAC Circuitry because its of some interest, with details of the Build and parts used and a short test.
BTW, I probably made a Mistake by saying that Pin Connectors J2 on the Board is for Infrared, I rather think it's a Programing Header for the MCU.
Bellow some Links on the DAC summarisation technique to archive a Higher resolution.
