Measurement Tolerance for Calibration
Measurement Tolerance for Calibration
(OP)
Greetings!
I'm working on a calibration plan where tolerance is part of the requirement as basis on when to conduct a calibration for pressure, flow, level, temperature, pH and conductivity transmitters aside from the frequency. On mechanical-type gauges, are tolerances of these instruments be the same as the transmitters?
Ideally, what are the tolerances of these instruments? Is 2.0% of FS acceptable?
Thanks
