Socket & See Proving Unit SP400
The Socket & See Proving Unit SP400 provides a safe and practical way of ascertaining if a multimeter or a two pole Voltage Indicator (VIs) is functioning correctly. An essential test, to be performed both before and after an instrument is used as advised in the Working Practice for electricians. In addition, the SP400 also features a test pad for operators to prove their non contact voltage detector.
Utilising an intelligent volt ramp for testing, the SP400 generates a test voltage which replicates a realistic AC mains supply frequency of 50Hz, for both safety and consistency. The unit generates between 50 – 690V in 5 steps (50V, 100V, 230V, 400V & 690V) with a true AC waveform output for reliable results. The Sp400 will also test two-pole VIs which use small incandescent lamps as evidence of voltage being present.
The bright LEDs of the lightweight and compact SP400 Proving Unit provides the electrical engineer with clear indication of voltage. Battery powered, with a rugged outer case and auto off function, this is an efficient, easy to use and versatile device.
