Pyrometry Calibration Start of cycle 2

[jallenc]

We use Fluke meters while performing SATs.
I recently sent two meters out for calibration which the new re-calibration date is 30 days.
Is it permissible to hold one unit back 15 days and release it with a new label staring the 30 day cycle so the calibration of the units will be staggered.

So, why not send it 15 days early? There's nothing that says you have to wait until the cycle expires.

I guess my question wasn't clear.
If a meter is sitting on the shelf and has not been used since it's last calibration, what would change in 30 days that would require it to be re-calibrated? Could it be issued with a new label without calibrating it? I have at least 10 meters and would like to ensure that I am not over calibrating just because a recall date has come up and the unit was never released from the cabinet where it is stored.

Drift, aging, etc.

I'm unclear why it's so darn short, though. You should investigate what the actual calibration consists of, and whether there is anything changing at all.

This issue shold be addressed by your quality system. Unless there is a clause that gives you permission to do what you are asking, in general, it would not be allowed.

IRstuff is right on, in my opinion. Yes, there can be issues that occur whether or not the uint has been used, but 30 days seems to be a rather short re-cal schedule. Often, these schedules get decided by people who know little or nothing about the instrument, so they make the best decision they can with what they know, figuring that if it is a problem, someone will question it and ask to get the schedule changed. As mentioned, look into what the calibration consists of and see if you can get the policy changed.

6 months is the shortest I've heard of. Otherwise, how does you management justify, assuming a week for cal, less than 75% availability of ostensibly critical equipment?
