Fluke 240V AC/DC Proving Unit provides AC and DC voltages for all high impedance instruments in your toolbox. When paired with the included TPAK magnetic hanging strip and the long battery life, including this proving unit in your toolbox is an easy decision. Verify your test tool works without unnecessary exposure to shock and arc flash. Make the process easy by using the PRV240FS Proving unit. Verifying that your T6 electrical tester is working properly reduces the need for personal protective equipment (PPE) when a known voltage source is not available for verification before tests are performed. (PPE is still needed for absence of voltage testing when appropriate).
