Martindale Electric says its new PD440 and PD430 portable proving devices can test contact voltage detectors up to 450V to ensure test lamps and voltage testers are operating correctly for safe working.
The devices are described as compact and can be carried around in an electricians’ tool kit so test instruments can be proved before and after working on any circuit. They are said to be suitable for use with Drummond test lamps, digital multimeters and low-impedance voltage testers, and offer a greater level of operator safety, as they generate voltages up to 450V.
The PD430 offers lower-voltage testing at 50V, because this voltage can be lethal and it is important to be able to prove your voltage indicator will illuminate at 50V – a requirement of IEC 61243.
