Black Star P240 Proving Unit 2mA 240V RS Calibration

A handheld, battery powered proving unit able to provide a nominal 240Vdc, 2mA source to prove the integrity of neon type test voltage indicators
For safety, voltage indicators should be checked for correct operation from this known voltage source before and after every use
The unit is housed in a compact ABS plastic case and fitted with a belt clip for convenience
An LED is used to indicate battery condition

This product will only work with test voltage indicators that have an input impedance of greater than 120kΩ.
