6 AA alkaline batteries & instructions

The Socket & See professional proving unit has an output voltage rating ranging between 50V and 690V. This model provides a safe and reliable means of checking the correct operation of Multimeters and two-pole voltage Indicators (VI). The 2-pole voltage testers recommended by the HSE should be proved on a known live source or proving unit both, before and after use. It should always be proved that any system is dead before commencing work.
