Fluke PRV240FS Proving Unit: Test Voltage Indicators

The Fluke PRV240FS Proving Unit is a compact, battery-powered voltage source designed to verify the functionality of electrical test tools. It provides a stable 240 V AC RMS or DC output to confirm the proper operation of test instruments before and after live measurements. This process, known as "Test Before Touch" (TBT), enhances safety by ensuring that instruments are functioning correctly, minimizing the risk of electrical hazards..

  • Special Features
  • Specification

The Fluke PRV240FS Proving Unit ensures that electrical test instruments are working properly by simulating a known voltage output for TBT verification. By confirming that the test equipment is functioning correctly, the risk of electrical hazards is significantly reduced. The device includes both visual and audible indicators to alert users when voltage is present, ensuring fast and safe verification of tool operation. Its small form factor and extended battery life make it suitable for field use, especially for technicians working with sensitive electrical systems.

  • Dual Voltage Output: Provides a stable 240 V AC RMS or DC output, suitable for both high and low impedance instruments.

  • FieldSense Compatibility: Specifically designed to verify the operation of the FieldSense function on Fluke T6 electrical testers.

  • LED Indicators: Provides clear visual feedback with LEDs that show the presence of output voltage.

  • Safety and Compliance: Complies with IEC61010-1 and IEC61010-2-030 standards to enhance safety by validating tools without direct contact with live circuits.

  • Long Battery Life: Operates for approximately 2,000 tests with a 10-second duration per test using AA batteries.

  • Compact and Portable: Lightweight and easy to transport with dimensions of 11.7 cm x 7.4 cm x 4.5 cm and weighs only 0.32 kg.
