MARTINDALE VT28/PD LED VOLT TEST AND PROVING UNIT

Safely proving dead requires the use of a voltage indicator and a known live source to test it on, both prior to and after checking for voltage presence. The combination of the Martindale VT28 and PD690 proving unit allows you to do just that, ensuring that you always have a known source to test against. The VT28 is a two pole voltage indicator with bright LED indication as well as a digital readout on the clear LCD display. It will indicate AC or DC voltages from 12V to 690V. Additional tests include audible and optical continuity, single pole phase test and phase rotation testing.
