Socket & See VP400 Vehicle Proving Unit
This is the VP400 Vehicle Proving Unit which provides a safe and reliable means of checking the correct functioning of Multimeters and two pole indicators (Vis) before and after use as advised in the Working Practise for electricians. They also have the capability of checking the operation of non-contract voltage detectors.
It is designed to be permanently mounted and powered from a 12V vehicle supply. The instrument will also test two-pole VIs that use small incandescent lamps to indicate that voltage is present. There is a unique and logical safety function – the test voltage generated is at 50Hz to synthesise test at AC mains supply frequency – so it will always read correct using the AC range of your Tester or Multimeter.
The product is designed to be wired in to the 12V supply of a vehicle. RED (+12V) and BLACK (0V) and should be taken from a fused outlet. There is no difference in operation to the standard proving unit. There is an extra isolating circuit within the proving unit which maintains safety even in single fault conditions.
- Intelligent voltage ramp for testing multimeters and Voltage Indicators
- Generates from 50-690V with a true AC waveform output
- Non-contact voltage indicator test feature
- Powerful enough to light old filamnet style test lamps
- Automatic operation turn-off
