Martindale PD690S 690V Proving Unit

The Martindale PD690S Proving Unit can be used to ensure compliance with Electricity at Work Regulations: it is suitable for proving multimeters, high- and low-impedance voltage indicators, two-pole testers, and Drummond test lamps before and after use to ensure they are functioning correctly.

This unit has a single voltage output of 690V AC: the full voltage is supplied in contact with the instrument under investigation. The Martindale PD690S Proving Unit is color-coded to indicate that it has a voltage output of 690V AC, distinguishing it from the 440V models in Martindale’s series of PDS and PDSX Proving Units.

The Martindale PD690S Proving Unit is in a tough, low-profile, over-moulded case with a detachable, high-strength MG3 magnetic hanger. It is a small and lightweight instrument with a long battery life. The Auto Power Off function is designed to preserve the Martindale PD690S Proving Unit’s power, whilst its low battery indicator alerts the user when the batteries require attention.

The Martindale PD690S Proving Unit is an alternative to the industry-standard Martindale PD690 Proving Unit. It is ideal for contractors and maintenance teams requiring a tool to prove multimeters, test lamps, two-pole testers, and voltage indicators quickly, simply, and safely.
