  • Compatible with both high impedance or low impedance multimeters, clamp meters or two-pole voltage and continuity testers

Product overview: Fluke PRV240 Proving Unit

The Fluke PRV240 Proving Unit is a portable, pocket-sized, battery-powered voltage source. It is unique in that it sources stable ac and dc voltages for both LoZ and HiZ instruments.

Fluke proving unit- Designed for safety and compliance

The Fluke PRV240 proving unit provides a safe method to verify that your electrical test tool is operating properly before you conduct any live tests. The concept of “Test Before Touch” (TBT) involves testing your meter against a known live source before and after the actual measurement. This sequence verifies that your test tool is operating properly during the actual measurement.

Verify your test tool without unnecessary exposure to shock and arc flash. Using the fluke electrical proving unit reduces the need for personal protective equipment (PPE) when a known voltage source is not available for verification of your tester or multimeter before test before TBT are performed. PPE is still needed for absence of voltage testing when appropriate.

Product Highlights

  • A single LED indicates functionality, making this unit a simple-to-use solution for complying with TBT verification of your test tool
  • Voltage is sourced through recessed contacts that are activated when tested probes are inserted to avoid accidental contact
  • Includes TPak™ Magnetic Hanging Strap
  • Long battery life—5,000 tests per set of four AA batteries
