Fluke PRV240 Proving Unit

• Stable Voltage Output: Provides 240 V AC/DC for HiZ and LoZ instruments, with ±10% accuracy at ≥1 MΩ load. 

• Safety Focused: Validates test tool functionality without live circuits, reducing shock and arc flash risks. 

• Simple Operation: Single LED indicates active voltage; recessed contacts prevent accidental activation. 

• Broad Compatibility: Works with multimeters, clamp meters, and two-pole testers. 

• Long Battery Life: 5,000 tests with four AA batteries, includes TPAK magnetic hanger. 

• Durable Design: One-year warranty, IP30 rating, and compact 117 mm x 74 mm x 28 mm size.

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.
