Unique, compact, convenient

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.

Designed for safety and compliance

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.

Key Benefits:

• 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)
