Socket & See SP400 Proving Unit
Provides a safe and reliable means of checking the correct functioning of Multimeters and two pole Voltage Indicators (VIs) before and after use as advised in the Working Practice for electricians.  Additionally they have the capability of checking the operation of Non-contact voltage detectors.
The SP400 will also test two-pole Voltage indicators that use small incandescent lamps to indicate that voltage is present.  SP400 has a unique and logical safety function � the test voltage generated is at 50Hz to synthesise a genuine test at AC mains supply frequency � so it will always read correct using the AC range of your Tester or Multimeter.
