The Fluke PRV240 Proving Unit is a cracking, pocket-sized solution for electricians needing to verify test tools like multimeters, clamp meters, or two-pole testers before live electrical work, ensuring compliance with “Test Before Touch” (TBT) protocols. It sources a stable 240 V AC/DC (±10% at ≥1 MΩ load, 60 V AC typical for LoZ) through recessed contacts, activated only by inserted probes to avoid mishaps, with a single LED signaling functionality.
By eliminating the need for live voltage sources, it slashes shock and arc flash risks, often reducing PPE requirements for pre-test verification. Compatible with both high and low impedance instruments, its compact 117 mm x 74 mm x 28 mm design weighs just 0.23 kg and includes a TPAK magnetic hanger for hands-free use. Powered by four AA batteries for up to 5,000 tests and backed by a one-year warranty, the PRV240 is a reliable, user-friendly mate for boosting safety and confidence in electrical testing across industrial and commercial settings.
