Martindale PD690S 690V Proving Unit

Essential for implementing effective safe isolation procedures and simply proves the operation of voltage indicators and test lamps up to 690V

Martindale PD690S 690V AC Proving Unit

The use of a voltage indicator has to be proven with a suitable proving device before and after use to ensure the instrument is working correctly in accordance with the Electricity at Work Regulations.

The Martindale PD690S voltage output is matched to the VI-15000, MTL15 Drummond test lamp and all other 690V voltage indicators and two pole testers including the VT12, VT25 and VT28.

The PD690S features a tough overmoulded low profile case and comes with an MG3 magnetic hanger (excluding kits). It is fast and easy to use, instantly supplying the 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.

It’s good practice to match the output voltage of the proving unit with the voltage range of the instrument to be proved.
