Martindale Electric’s New Proving Devices PD440 and PD430 – portable, battery-powered, and designed for the testing of contact voltage detectors up to 450V to ensure test lamps and voltage testers are operating correctly for safe working.
Suitable for use with Drummond Test Lamps, Digital Multimeters, and Low Impedance Voltage Testers, Martindale’s new Proving Devices offer a greater level of operator safety as they generate voltages up to 450V.
Voltage indicators should prove the normal working voltage. The use of higher voltages than seen in the real world can be misleading.
The PD430 adds a lower voltage range of 50V. This is because 50V can be lethal so it is important for extra safety that you can prove your voltage indicator will illuminate at 50V, which is a requirement of IEC 61243.
Compact and lightweight, the new proving devices can easily be carried around in an electricians’ tool kit so test instruments can be proved before and after working on any circuit as advocated by the Electrical Safety Council.
The Martindale PD440 is a 440V AC proving device, designed to enable voltage indicators to be fully checked, in compliance with Health & Safety recommendations.
The-PD440’s designed to prove the working of voltage detectors used on single and 3 phase supplies.
The-PD440 is compatible with ANY MAKE of 2 Pole Voltage and Continuity Testers.
The PD440 can also check Drummond and other filament test lamps as well as standard multimeters two pole voltage indicators.
Using a voltage indicator without first proving it is working correctly could prove fatal.
