FLUKE FLUKE PRV240

The FLUKE PRV240 is a Proving Unit for use with electrical test tool. It 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. It 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 this 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.
