DescriptionMartindale PD690S 690V AC Proving UnitProduct Description:The Martindale PD690S is a high-performance proving unit designed for verifying the functionality of 690V AC voltage indicators and two-pole testers. A direct replacement for the industry-standard PD690, this device ensures compliance with the Electricity at Work Regulations by allowing electrical professionals to test their voltage indicators before and after use. The PD690S outputs a voltage perfectly suited for use with the VI-15000, MTL15 Drummond test lamp, and other 690V voltage indicators such as the VT12, VT25, and VT28.The PD690S model features a robust, overmoulded, low-profile case that enhances durability while maintaining a compact design. It also includes an MG3 magnetic hanger for convenient hands-free use. This proving unit is quick and easy to use, providing instant test voltage for both high and low impedance voltage indicators, test lamps, and meters. Once the high voltage test is complete, the unit produces a low resistance across the terminals, confirming the continuity function of two-pole testers. The color-coded design simplifies matching the proving unit with corresponding Martindale voltage indicators, ensuring ease of use and reducing the risk of error during testing.Key Features:Designed for use with 690V AC voltage indicators, test lamps, and two-pole testersRobust, overmoulded low-profile case for durability and easy handlingFast and easy to use, supplying instant test voltage for both high and low impedance testersIncludes MG3 magnetic hanger for hands-free operation during testingFeatures a low-resistance check after the high voltage test to verify continuity of two-pole testersWhat’s Included:Martindale PD690S 690V AC proving unitMG3 magnetic hanging strap6x AA alkaline batteries
