Multifunction Tester Calibration – What Factors Affect Calibration?

Multifunction tester calibration is pivotal for maintaining instrument accuracy. This is the process of configuring an instrument to supply a result for a sample within a suitable range. This is vital for improving performance in test and measurement hire equipment, as well as a wide range of other items. Of course, it is pivotal that calibration is carried out effectively to ensure potential errors do not degrade the results. So, let’s take a look at some of the factors that impact the result of calibration. Firstly, we have the calibrator values. It is pivotal to ensure instructions are expertly followed during the calibration process.

Selecting the wrong calibrator values is a big issue, which effectively ‘teaches’ the instrument incorrectly. This leads to considerable mistakes over the full operating range. Some instruments do have software diagnostics in place that will alert operators if calibrators are tested in the wrong order, but the item that is being tested may accept one or more calibrators of the incorrect value without accepting error. Another factor that influences test equipment calibration is calibrator formulation tolerance. It is vital that calibrators are formulated to a reputable manufacturer’s tight tolerance specifications. This is because tolerance can influence the mean value obtained during the process.

Hopefully, you now have a better understanding of two of the vital factors that can influence the outcome of calibration. This highlights why it is pivotal to choose a calibration service with care.
