Fluke PRV240 Portable Voltage Proving Unit

The Fluke PRV240 Portable Proving Unit provides a safe, controlled 240 V AC/DC source for verifying the performance of electrical test instruments before and after live measurements. Designed for technicians following Test Before Touch (TBT) procedures, it ensures your meter is working correctly without exposure to electrical hazards.

This compact, battery-powered proving unit is ideal for electricians, maintenance teams, and safety professionals who need a dependable voltage reference when a known live source isn’t available.

Key Features

• Safe verification before live testing: Confirms electrical tester functionality prior to high-risk measurements, supporting TBT safety protocols.

• AC and DC output: Delivers stable 240 V AC and DC for compatibility with a wide range of test tools.

• Works with HiZ and LoZ instruments: Suitable for multimeters, clamp meters, and two-pole testers.

• Portable, pocket-sized design: Easy to carry and operate in the field.

• Recessed contacts: Voltage is only activated when probes are inserted, reducing accidental exposure.

• Simple LED status indicator: Indicates proper unit functionality.

• Long battery life: Supports up to 5,000 tests on four AA batteries.

Benefits

• Improves safety compliance: Helps reduce shock and arc-flash risk by eliminating the need to use an energized circuit for verification.

• Supports PPE reduction: Minimizes unnecessary PPE usage when a known voltage source is unavailable.

• Reliable performance anywhere: Operates independently of site power, ensuring consistent test readiness.

• Versatile tool compatibility: Works with virtually any electrical measurement instrument used for voltage validation.
