Ok here we go with another.
Currently we have a department that has no PM program so the -70 freezers get a good thick build up of frost. I'm being told to have them empty the freezer before taking the "As Found" data. Then after it's defrosted and we do a "as Left" Calibration we find that the RTD Probe is reading over 3 degrees off from our Temp Standard. Our tolerance is +/- 1 degree C
So in effect we have changed the environment before the "As Found" and changed it even more by defrosting before the "As Calibrated". Of course only my boss says this is the correct way to do things. And that this calibration does not require an "Out of Calibration" report.
Does anyone agree with this? I haven't found but one person so far mentioned above. I'd love to here some replies.
