Fluke PRV240 Proving Unit 240V AC/DC Source NIST Calibrated
Product Information
The Fluke PRV240 Proving Unit is a portable, pocket-sized, battery-powered voltage source. It is unique because it sources stable AC and DC voltages for both LoZ and HiZ instruments.
The Fluke PRV240 provides a safe method to verify that your electrical test tool is operating properly before and after 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 through the actual measurement.
A single LED on the PRV240 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.
