Product Details:

Always prove your Voltage Indicator is working before you touch a circuit you think is dead.

Nothing is more dangerous than trusting a defective Voltage Indicator.

The Martindale package of VI13800 and PD440 Proving Unit is an essential safety aid for electricians and comes with a carry case.

Martindale VIPD138-S Two Pole Safety Voltage Tester and PD440S Proving Unit complete with Protective Case

This Kit comprises the following 3 items:

  • 1 x Martindale VI13800 Fuseless Voltage Indicator
  • 1 x Martindale PD440S – 440V Proving Device
  • 1 x Martindale TC69 VIPD Two-Pole Voltage Tester & Proving Unit Carry Case

Martindale VI13800 Fuseless Voltage Indicator:

The new VI13800 does NOT have a fuse.

This is so that it will comply with BS EN61243-3 2010 which came into force in May 2013. This standard bans the use of fuses in 2 pole voltage indicators.

The VI13800 shows all the key safety characteristics of the older VI-13700/2. It has retractable prods, cable with an inner cover of a different color to quickly identify damaged cables and impedances at both ends to limit current flow if a leader should be broken, eg. by being sheared in a steel cabinet.

Key Features:

  • Industry-standard voltage indicator
  • Fully GS38 compliant
  • Heavy-duty double insulated leads
  • Bright LEDs
  • Polarity Indication

Martindale PD440S – 440V Proving Device

Martindale Electric’s New PD440S and PD440SX Proving Devices are portable, battery-powered, and designed for the testing of contact voltage detectors up to 450V to ensure test lamps and voltage testers are operating correctly for safe working.

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.

Voltage indicators should be proven at the normal working voltage. The use of higher voltages than seen in the real world can be misleading.

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 PD440S and PD440SX proving devices are supplied complete with batteries as with all instrumentation supplied by Martindale Electric, come with a comprehensive two-year guarantee.

The Martindale PD440S is a 440V AC proving device, designed to enable voltage indicators to be fully checked, in compliance with Health & Safety recommendations.

The PD440S is designed to prove the working of voltage detectors used on single and 3 phase supplies.

The PD440S and PD440SX are compatible with the Martindale VI13700G, the new Martindale VI13700/2 and the fuseless VI13800 Voltage Indicators. The PD440 can also be used to check Drummond and other filament test lamps as well as standard multimeters and other manufacturers’ two-pole voltage indicators.

Using a voltage indicator without first proving it is working correctly could prove fatal.
