Hi, when in instrument that is usually calibrated is no longer required, should it be sent for calibration before being discarded to ensure it has been peforming correctly since the previous calibration?
...based on the assessment of risk...
And verified...not calibrated as originally asked. Agreed.
Likely falls into the age old semantics of Calibration vs. Verification.
The point is to know if your last measurement before discard is reliable (and thus the ones before that too)...not to have the equipment "adjusted" so that the next measurement is reliable...being that there is no next measurement.
To me that's verification...and if I can do that in-house fast and cheap to give me the confidence I'll need to trust the last usage data, I'm all good.
We're saying the same thing, I figure...
