The PRV240 proving unit provides a safe and convenient method for “test before touch” (TBT) verification of electrical test tools without placing the user in potentially hazardous electrical environments. Designed to eliminate the need for PPE, the pocket-sized unit sources 240V of both AC and DC steady-state voltage for testing of high- and low-impedance multimeters, clamp meters, and two-pole testers, eliminating both the need for multiple verification tools and the use of a known high-energy voltage source for test instrument verification. To avoid accidental contact, the voltage is supplied through recessed contacts that are activated only when test probes are inserted into the modules insulated access points. A single LED indicates the sourcing of the voltage to verify the test tool. In addition, the product can perform up to 5,000 tests per set of four AA batteries and comes with a TPAK magnetic hanging strap
