Just out of curiosity why is the calibration interval 1yr for lab instruments like DMM, scope etc.
Why not 2 years.
Also, you use a higher accuracy bench DMM to calibrate a hand held DMM.
Instead of getting calibration done by an outside agency, Why not calibrate the handheld DMM yourself using an already calibrated bench DMM.
I am trying to ask if "self-calibration" is accepted in the industry.
