For safe electrical work you require the use of a voltage indicator that has been proven with a suitable proving device such as the Martindale PD690S 690V AC Proving Unit before and after use to ensure the instrument is working correctly.
The Martindale PD690S 690V AC Proving Unit come in an overmoulded low profile case with magnetic hanger.
The PD690S is fast and easy to use, instantly supplying the full test voltage for both high and low impedance voltage indicators, test lamps and meters. On completion of the high voltage test, a low resistance appears across the terminals to verify the continuity function of two pole testers.
