Socket & See SP200 Professional Proving Unit
Reliable Proving for Voltage Indicators and Multimeters
The Socket & See SP200 Professional Proving Unit provides a safe and reliable way to check the correct operation of two-pole voltage indicators and multimeters both before and after use. This compact Socket & See Proving Unit generates test voltages from 50V to 690V, making it a practical choice for electricians carrying out routine electrical testing.
The Socket & See SP200 features an intelligent voltage ramp that increases and decreases the output voltage, mimicking the ramp feature on compatible voltage indicators. Unlike many other proving units, the SP200 generates a true AC waveform using just six AA alkaline batteries and can carry out many hundreds of proving checks from a single set of batteries.
