DeFelsko PosiTest HHD Verifier, 0.5 to 35 kV

Availability: 1 to 2 Weeks

DeFelsko HHDVERIFY Offers

Features

• Ideal for field/laboratory verification of pulse or continuous DC holiday detectors
• Wide measurement range
• Simple two step operation
• Lightweight and portable - requires no external power source

Easy operation

Before using this verifier, ensure that proper ground is established between the holiday detector and the verifier. Ensure that the ground lead is plugged into the 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 verifier on by pressing and releasing the power button. Once powered on, the verifier continuously monitors the voltage on the probe tip. The voltage displayed on the verifier should match the voltage displayed by the detector within the combined tolerance of both units.

For DC holiday detectors such as the PosiTest HHD and PosiTest HHD C, the verifier probe tip can be left connected to an exposed electrode indefinitely with no concern. For best results, try to position the verifier probe perpendicular (90°) to the electrode on the holiday detector.

Applications

• Field
• Laboratory
