Fluke PRV240 Proving Unit

The Fluke PRV240 Proving Unit is a portable, battery-powered voltage source designed to verify the functionality of electrical test tools before and after live measurements. It supplies a stable 240 V AC/DC output, ensuring accurate "Test Before Touch" (TBT) verification without the need for direct contact with live circuits..

  • Detail
  • Special Features
  • Specification

The Fluke PRV240 Proving Unit is engineered to provide a safe and efficient method for verifying the operation of electrical test tools. By simulating a known voltage source, it allows technicians to confirm the functionality of their instruments before and after live measurements, adhering to the TBT protocol. This practice enhances safety by ensuring that tools are operating correctly, thereby minimizing the risk of electrical hazards.

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

  • Safety Compliance: Meets IEC61010-1 and IEC61010-2-030 standards, reducing the risk of shock and arc flash.

  • Long Battery Life: Operates for approximately 5,000 tests with a 5-second duration per test using four AA batteries.

  • Compact Design: Lightweight and portable, measuring 11.7 cm x 7.4 cm x 2.8 cm and weighing 0.23 kg.

  • Magnetic Hanging Strap: Includes a TPAK™ magnetic strap for hands-free operation.
