Very good! I don’t know how often one should do this.
- But good to try and have a regular schedule, say every two – three years on each individual instrument.
- Or if for some reson one suspect a failed instrument due to handling/transportation.
As I understand our agency get this external reviewer every year and they focus on different things. That year instrument calibration and ways to follow up calibration routines where a focus. I have now better ways to prove how our instruments are performing(distance made good test and a admin tool to follow it and store results).
