Voltage Proving Unit Calibration


Voltage Proving Units are used to prove whether your detectors and 2 pole voltage indicators are working correctly; suitable to prove High and Low Impedance devices such as multimeters and clamps.

Battery-powered Voltage Proving Units are intended to be lightweight and compact devices for ensuring safe operation when working with electricity. They serve as a verification step to safely working with high or even low voltages. They should be utilised regularly (not just with unfamiliar/new equipment) during any installation procedures.
