Fluke PRV240 | 240V AC/DC Proving Unit for Electrical Test Tools

Verify a voltage tester or multimeter before and after critical electrical work, but finding a known live circuit solely to check the instrument can introduce unnecessary exposure. The Fluke PRV240 Proving Unit provides a compact, battery-powered source to confirm that electrical test tools are functioning correctly.

The unit produces a stable 240 V AC or DC output and supports both high-impedance and low-impedance instruments. Recessed output contacts are activated when test probes are inserted, helping reduce accidental contact with the proving terminals. A single LED indicates output functionality, keeping operation simple for field technicians. Because it can verify multimeters, clamp meters and two-pole testers away from an energized installation, the PRV240 supports good test-before-touch working practice while reducing reliance on an uncontrolled live source.

Proving Unit Selection Guide

Choose the PRV240 for routine verification of HiZ and LoZ multimeters, clamp meters and two-pole testers. Select the PRV240FS when you must also verify FieldSense functionality on Fluke T6 testers.

Market Relevance
