In addition to all the benefits of the industry standard Martindale PD440 and PD690 proving units, the S models feature a tough overmoulded low profile case and come with an MG3 magnetic hanger (excluding kits). They are fast and easy to use, instantly supplying the test voltage for both high and low impedance voltage indicators, test lamps and meters. 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 Martindale PD440S is a direct replacement for the industry standard PD440. Its voltage output is matched to the VI13800, the MTL10 and MTL20 Drummond test lamps and all other 440V voltage indicators and testers. The Martindale VT12PD-S Voltage Tester & Proving Unit Kit can be used to maintain compliance with safe isolation and proving dead procedures. To this end it includes:The 440V industry-leading PD440S Proving Unit is suitable for verifying high and low impedance voltage testers; for maximum convenience, it can be used through the TC71 Carry Case. The Martindale VI13800 Voltage Indicator can identify voltages between 50V and 600V AC/DC; it includes dedicated LEDs for indicating the voltage range. The Martindale VI13800 Voltage Indicator also features a bright LED for polarity indication. Finally, it is GS38 and BS EN61243-3 compliant and features a heavy-duty, double-insulated cable with a contrasting inner core to reveal any damage. The Martindale VIPD138-S Voltage Indicator & Proving Unit Kit is a safe isolation set consisting of a Martindale VI13800 Voltage Indicator, PD440S Proving Unit, and TC71 Combination Carry Case. Containing equipment required to follow safe isolation procedures, it is an essential safety aid for electricians, and service and maintenance technicians. 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 to 450V.

The indicator contains bright neon lights with extended life which give a fast effective display of voltage level range. Martindale have designed the instrument with safety in mind with double insulated test leads and finger guards to prevent the possibility of slipping onto live circuits.
