Easy Operation


Ensure that the ground lead is plugged into the PosiTest HHD Verifier and that the other end of the ground lead is connected to the ground lead of the high voltage holiday detector that is being verified.


Turn the PosiTest HHD Verifier on by pressing and releasing the power button. Once powered on, the verifier continuously monitors the voltage on the probe on the end of the verifier. The verifier will update the display when the probe is touching an exposed electrode of a holiday detector. The voltage displayed on the verifier should match the voltage displayed on the detector within the combined tolerance of both units. For Continuous DC holiday detectors, the verifier probe tip should just be tapped against an exposed electrode to obtain a measurement.


What is the PosiTest HHD Verifier?

The PosiTest HHD Verifier is a calibrated voltmeter (crest meter, jeep meter) ideal for verifying the operating voltage of both Pulse and Continuous DC holiday detectors in the range from 500 to 35,000 Volts.

Is the PosiTest HHD Verifier necessary to use the PosiTest HHD High voltage Holiday Detector?

No. The PosiTest HHD features a built-in voltmeter (crest meter, jeep meter) with a traceable Long Form Certificate of Calibration. However, some standards call for a standalone voltmeter.
