The Martindale PD440 is a 440V AC proving device, designed to enable voltage indicators to be fully checked, in compliance with Health & Safety recommendations. Using a voltage indicator without first proving it is working correctly could prove fatal.
The PD440 is compatible with the new Martindale VI13800 & the Martindale VI13700.
It can also be used to check Drummond and other filament test lamps as well as standard multimeters and other manufacturers two pole voltage indicators.
There is now a facility to power the PD440 proving devices with the addition of a 12V DC power connection point. The units can be powered by either alkaline batteries or a 12V power supply. There are two power supply units available for the proving devices, the PSUPD230 and the PSUHPAT12. The PSUPD230 can be connected to mains power and the PSUHPAT12 is a 12v power supply suitable for use in a car/van cigarette lighter.
