If I had to summarize the content of this post into one sentence, it would be:

Using a mA meter with an internal impedance that is too high to measure current over the transmitter’s test connection will result in erroneous measurement results!

Calibration Out of Tolerance – Part 2

Posted by Heikki Laurila on Feb 2, 2017 3:10:26 PM

In this post I continue on the topic of calibration being “Out of Tolerance” (OoT) or “Failed”.

“Out of Tolerance” (OoT) means that during a calibration some calibration point(s) failed to meet the required tolerance level. This causes the result of the calibration to be out of tolerance, or as often also referred to, that it was a failed calibration.

Metrological Traceability in Calibration – Are you traceable?

Posted by Heikki Laurila on Jan 18, 2017 11:57:22 AM

What is metrological traceability in calibration and how can you be traceable?

Metrological Traceability in Calibration – Are you traceable?

In calibration, the metrological traceability is a fundamental consideration. If the calibrations you perform in your plant are not traceable, you don’t know if they are correct or not and therefore there is really no point in doing them.
