Martindale’s PD440SX proves the operation of voltage indicators, multimeters and test lamps up to 440V: The PD440SX is fast and easy to use, instantly supplying the full test voltage for both high and low–impedance voltage indicators, test lamps and meters. Individual LED indicators matched to voltage indicator thresholds.
The CALCHECK feature makes it easy to verify the insulation and low resistance ranges on 18th Edition multifunction instruments and single function insulation testers on-site, making it ideal for identifying potential calibration issues with a multifunction tester prior to certifying a new wiring installation or carrying out a condition report. It’s also a valuable procedure recognised by electrical contractor assessment bodies.
It comes complete with an over-moulded low-profile case and magnetic hanger.
