Multimeter Calibration Services

To perform multimeter calibration, PCS uses the latest Fluke process calibrators to source and measure AC Current, DC Current, AC Voltage, DC Voltage, Capacitance, and Resistance. We calibrate multimeters by testing several reference points throughout the range of each applicable function or “mode”of the meter.

As an example, if we are calibrating a multimeter that measures AC/DC voltage, AC/DC current, and resistance, we would begin by selecting the AC Voltage measurement mode and test several points across the entire AC Voltage scale at known values generated by our Fluke 5522a process calibrator. Once we have collected the “as found” data of the AC voltage function, we make adjustments (if needed) to the bring the multimeter back in tolerance and subsequently obtain and report  the “as left” data of the unit.

After testing the AC voltage scale on the multimeter, we would repeat the same general procedure for DC voltage, AC current, DC current, resistance and capacitance until all functions have been tested. Performing multimeter calibration in this manner guarantees that your equipment is valid across all operational ranges in every mode. If you have a multimeter or process meter that “sources” various functions, we will use at least a 6.5 digit bench meter to measure several points across the range of each mode.
