In metrology we have similar benign bits of hardware that can create havoc if misapplied, but in the grand scheme of things rarely are.

Many calibration customers become frustrated with their calibration sources because of price changes after they’ve sent a purchase order and the gages to the lab.

This question is rarely, if ever, asked but assumptions regarding the length of time involved regularly pop up, especially when measurement disputes are the situation into which such assumptions are injected.

Just so there’s no misunderstanding, the ‘PC’ referred to in the title is not about political correctness, a very bad disease in its own right. In this case it’s about panic calibration.

On the surface, it would seem there is little to be done when looking at calibration services.

This one starts innocently enough, but is difficult to stop.

Ask what the process is supposed to do. 

The MC4 is a documenting process calibrator for various process parameters, such as pressure, temperature and electrical signals.
