PRV240
The Fluke PRV240 proving unit is a portable, pocket-sized, battery-powered voltage source. It is unique in that it sources stable AC and DC voltages for both LoZ and HiZ instruments. The PRV240 reduces the risk of shock and arc flash by removing unnecessary exposure to a potentially hazardous electrical environment while verifying the functionality of test tools before and after absence or presence of voltage is checked.

Output voltage: 240V AC RMS or DC (±10% ≥1MΩ). LoZ>3kΩ load (60V AC typical, 50V AC RMS minimum).
Operating temperature: -10°C to +50°C.
Safety: IEC61010-1, IEC61010-2-030.
