Martindale PD690SX Proving Unit 690V AC

With Martindales' unique CALCHECK feature.

Safe electrical working requires using a voltage indicator that has been 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.
With all the benefits of the industry standard Martindale PD440 and PD690 proving units, the new S models come in an overmoulded low-profile case with a magnetic hanger. They are fast and easy to use, instantly supplying the full test voltage for both high and low-impedance voltage indicators, test lamps, and meters.

The SX Series has a unique CALCHECK feature making it easy to verify the insulation and low resistance ranges on 18th Edition multifunction testers, wherever you are working. In addition, the new SX models have stepped voltage LEDs with thresholds matched to most voltage indicators and two pole testers.

CALCHECK makes it easy to verify the insulation and low resistance ranges on 18th Edition multifunction instruments and single-function insulation testers on-site, making it ideal for identifying potential calibration issues with test equipment before certifying a new wiring installation or carrying out a condition report. This is a valuable procedure recognised by electrical contractor assessment bodies to ensure reliable results and avoid unnecessary and expensive retests.
