Socket & See SP400 Proving Unit
The Socket & See SP400 Proving Unit is an essential tool for electricians. It ensures the accurate functioning of multimeters and two-pole voltage indicators (VIs) both before and after use. The unit generates a true AC waveform output ranging from 50 to 690V. This provides reliable testing at the same frequency as the mains supply. The SP400 not only verifies standard multimeters and VIs but also accommodates non-contact voltage detectors like the VVD PRO. This makes it highly versatile for on-site testing and maintenance tasks.

Built with an intelligent voltage ramp, the SP400 tests all voltage ranges, from the lowest 50V to the highest 690V, with precise increments, guaranteeing a comprehensive evaluation of your equipment. Its robust design is powerful enough to light up old filament-style test lamps, a testament to its effectiveness in real-world conditions. The automatic operation and turn-off features ensure that the unit is user-friendly and energy-efficient, extending the life of the batteries.

Weighing just 346 grams, this compact proving unit is easily portable, making it ideal for quick and efficient checks in the field. With a reliable performance in diverse conditions, the SP400 proves to be an indispensable asset for any professional looking to adhere to the best practices outlined in the Working Practice for Electricians. Whether you are testing new digital multimeters or older devices, the Socket & See SP400 delivers dependable results every time.
