The PD240 is a convenient pocket-sized, battery powered proving unit that produces a 240V DC output. Any device used for voltage detection and for proving dead should be tested before and after use to ensure the safety of the operative.

The PD240 is current limited to 2mA and is suitable for use with multimeters and other voltage detectors that have an input impedance greater than 120kΩ. The unit is actuated by microswitch when probes of a voltage detector are inserted into the probe apertures on front face. The Indicator LED adjacent to probe apertures shows when the proving unit is powered.

Switch-mode electronics ensure long battery life and a flush-mounted pocket clip permits stable bench use when desired.
