Martindale Electric’s New Proving Devices PD440 and PD430 are 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. Martindale Electric’s New Proving Devices PD440 and PD430 are 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 450V.
Voltage indicators should be proven at the normal working voltage. 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 PD430 and PD440 proving devices are supplied complete with batteries as with all instrumentation supplied by Martindale Electric, come with a comprehensive two year guarantee.
