Martindale VIPD138 Safety Voltage & Proving Unit


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.

  • 1 x Martindale VI13800 Fuseless Voltage Indicator
  • 1 x Martindale PD440 – 440V Proving Device
  • 1 x Martindale TC69 VIPD Two Pole Voltage Tester & Proving Unit Carry Case
  • 1 Month Warranty


Martindale VI13800 Fuseless Voltage Indicator

The VI13800 is an essential tool for proving electrical circuits are dead before carrying out maintenance and installation work in accordance with safe isolation procedures. The VI13800 ensures safety through simplicity, with no ranges, switches or batteries, reducing the risk of an incorrect reading.

The VI13800 provides instant visual AC and DC voltage indication in four stages from 50V to 400V. The bright long life LED indicators give clear and immediate display of the voltage level range. It has retractable probes, heavy duty finger guards and a two layer double insulated cable with a white inner core to give clear indication of damage that might compromise the user’s safety.

The latest design complies with the new standard relating to 2 pole voltage indicator, BS EN61243-3 and the requirements of GS38 Edition 4 2015. The latest version of BS EN61243-3:2010 came fully in to force in May 2013 and all voltage indicators on the British & European market should comply. The VI13800 replaces the industry standard VI13700.

Based on the VI13700, the new design includes a high wattage resistor instead of a fuse that will limit the current in the event of damage to the cable in accordance with BS EN61243-3. The protection is built in where it’s needed, in the handheld probe assembly rather than just in the instrument providing superior protection for the user to other testers. The probes tips have retractable covers which can be locked in place and can’t get lost.
The Martindale VI13700 has been widely used for many years and as part of its design has always included a fuse in the probe to limit the current in the event of damage to the cable. Apart from the fuse/resistor enhancement in the probe everything else about the specification of the VI13800 is identical to the VI13700/2, including the contrasting inner cable sheath to quickly identify cable damage.In order to distinguish VI13700/2 from VI13800 the new model has the probe changed to all black instead of yellow. The probe is clearly marked “impedance protected” rather than showing a fuse rating. It is sealed and has no user replaceable parts.

There is no specific requirement to replace the VI13700 products which are in use. NB Proper proving procedures should always be used with any voltage indicator.

The new VI13800 is available to purchase on its own or as part of a kit, the VIPD138LOK, containing everything you need for on-site working. Kits includes a Martindale proving unit, combination carry case and locking off devices, enabling full compliance with health and safety recommendations for safe working which require voltage indicators to be proved before and after use and the point of isolation to be locked off with a caution notice.

Martindale PD440 – 440V Proving Device

Martindale Electric’s New Proving Devices PD440 and PD430 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 450V.

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

The PD430 adds a lower voltage range of 50V. This is because 50V can be lethal so it is important for extra safety that you can prove your voltage indicator will illuminate at 50V, which is a requirement of IEC 61243.

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 PD430 and PD440 proving devices are supplied complete with batteries as with all instrumentation supplied by Martindale Electric, come with a comprehensive two year guarantee.

The Martindale PD440 is a 440V AC proving device, designed to enable voltage indicators to be fully checked, in compliance with Health & Safety recommendations.

The PD440 is designed to prove the working of voltage detectors used on single and 3 phase supplies.

The PD440 is compatible with the Martindale VI13700G, the new Martindale VI13700/2 & 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.
