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!
In this article, I look at the practical considerations and the different tests you should perform when calibrating your weighing scales/instruments.
20 things you should consider when calibrating pressure gauges

It’s a jungle out there!
There is a lot of different pressure units in use around the world and sometimes this can be very confusing and may cause dangerous misunderstandings. In this blog post I will discuss the basics of different pressure units and different pressure unit families.
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.

What is metrological traceability in calibration and how can you be 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.
In this post we discuss the following scenario: You have done the calibration, have the results on the certificate and you compare results to the tolerance limits. It’s time to pop the big question: Is it a Passed or Failed calibration? Or is it In or Out of Tolerance?
