F.A.Q.
What is the difference between the DeFelsko PosiTest HHD Verifier and the DeFelsko PosiTest HHD C Verifier?
The DeFelsko PosiTest HHD Verifier is a calibrated voltmeter (crest meter, jeep meter) ideal for verifying the operating voltage of ALL Pulse type holiday detectors in the range from 500 to 35,000 Volts.
The DeFelsko PosiTest HHD C Verifier is a calibrated voltmeter (crest meter, jeep meter) ideal for verifying the operating voltage of ALL Continuous type holiday detectors in the range from 500 to 30,000 Volts.
Are PosiTest HHD Verifiers necessary to use the PosiTest HHD or HHD C High voltage Holiday Detectors?
No. The PosiTest HHD series feature a built-in voltmeter (crest meter, jeep meter) with a traceable Long Form Certificate of Calibration. However, some standards call for a standalone voltmeter.
