Fluke PRV240FS – Proving Unit for Field Sense Meters

• Provides a safe method to verify electrical test tool operation before and after you conduct any live tests
• Specifically built to prove the functionality of the FieldSense measurement on T6 testers
• Also compatible with other high impedance multimeters and clamp meters
• Supplies 240 V – both DC and AC
• Voltage is sourced through a central hub designed to test the T6 FieldSense open fork, as well as through recessed contacts that are activated when test probes are inserted to avoid accidental contact

The Fluke PRV240FS Proving Unit is a portable, pocket-sized, battery-powered voltage source. It is specifically built to prove the functionality of the FieldSense measurement on the T6 electrical testers. It also provides ac and dc voltages for other HiZ instruments in your tool box.

The Fluke PRV240FS provides a safe method to verify that your T6 electrical tester is operating properly before you conduct any live tests. The concept of “Test Before Touch” (TBT) involves testing your T6 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 PRV240FS 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.

• Using the PRV240FS reduces the risk of shock and arc flash by validating the functionality of test tools without placing yourself in a potentially hazardous electrical environment.
• Can prove functionality of the FieldSense measurement on the T6 electrical testers
• Sources both ac and dc steady-state voltage—supplies 240 V dc/ac.
• A single switch and a set of LEDs indicate functionality of both the FieldSense “no-test-lead” voltage measurement capability, plus standard ac and dc measurements with test leads. This unit is a simple-to-use solution for complying with TBT verification of your test tools.
• Compatible with high impedance multimeters or clamp meters.
• Voltage is sourced through a central hub designed to test the T6 FieldSense open fork, as well as through recessed contacts that are activated when test probes are inserted to avoid accidental contact
• Includes TPAK magnetic hanging strap
• Long battery life – 2000 tests per set of four AA batteries (10 second test average)
