    Martindale Voltage and Proving Kit – VIPD 138

    Martindale are currently the market leaders in Voltage Detection and the latest update to the VIPD Kit continues their reputation for highly accurate test equipment.

    The newest Martindale VIPD Kit includes the PD440 Proving device and the updated VI13800 Voltage Indicator packed within the TC57 Carry Case. (The previous kit included the VI13700/2)

    The new VI13800 safely checks for AC and DC voltages from 50V to 600V AC and DC as required by the Electricity Council.

    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.

    Along with GS38 safety compliant tips the kit now includes a voltage detector which complies with the latest BS EN61243-3:2010 standard for two pole indicators which came fully into force in May 2013.

    This update to the regulations state the previously standardised fused two pole indicators can cause unreliability. It is also possible for a fused indicator to fail to show hazardous voltage. Although the issue is deemed to be small the BS EN61243-3 prohibits the use of fuses in 2 pole voltage indicators.

    Martindale have replaced the fuse in favour of a high wattage resistor in the probe that limits the current in the event of a damaged cable. This allows for a reduction of the flow under a potential fault making the device much safer to use. It is interesting to point out that many competitors do not have any kind of protection within their probes.

    You can differentiate the new VI-13800 from the VI-13700/2 by the distinct black probe colour and its “impedance protected” marking the unit is also completely sealed. All other specifications from the VI-13700/2 remain the same including the high contrast inner cable effective when a cable is damaged.

    Accompanied in the kit is a PD440 proving unit which can prove contact type voltage indicators between 440V @ 500kΩ load or higher. The PD440 is a battery powered portable proving unit which can be used with a range of indicators with 230V and 415/440V AC or DC detection ranges. The device is also perfect for checking Drummond and other filament lamps due to its output being sufficient to illuminate the bulb.

    The Kit is supplied with a 2 year manufactures warranty.

    A Voltage Indicator should always be tested against a live source or proving unit to confirm the long term reliability of results given whilst testing live circuits.

    The Martindale Voltage and Proving Kit – VIPD 138 is the ideal kit for electricians, technicians and engineers looking to safely prove live and dead circuits in accordance with the Electricity at Work regulations..

    Voltage indicator indicates voltages - perfect. No annoying beeps or excess lights, unlike some other more complicated voltage indicators that warble and light up like a Christmas tree whenever the probe touches metal anywhere near the circuit you're testing. Spring-mounted probe covers work well. Proving unit does the job and seems robust.. Combined carry case (for both) is fine, with access to PU terminals (clear plastic front) without removing from case. All good.
