Fluke PRV240FS Proving Unit for FieldSense and High Impedance Testers

The Fluke PRV240FS Proving Unit delivers a safe, portable voltage source for verifying the functionality of FieldSense technology on T6 testers and other high-impedance instruments. It enables proper Test Before Touch (TBT) procedures by supplying 240 V AC or DC without exposing technicians to live circuits, reducing the risk of shock and arc flash during tool validation.

Key Features

• Purpose-built for FieldSense verification: Confirms proper function of Fluke T6 open-fork voltage testers

• Supplies 240 V AC and DC: Provides steady-state voltage output for multimeters, clamp meters, and other Hi-Z tools

• Central FieldSense hub: Designed for open-fork engagement plus recessed probe contacts for safer testing

• Supports Test Before Touch (TBT): Ensures electrical testers operate correctly before and after live measurements

• Long battery life: Delivers up to 2,000 tests per set of four AA batteries

• Portable and simple to use: Pocket-sized design with straightforward single-switch operation and LED indicators

• Reduced PPE requirements: Eliminates the need for a known energized source during tool verification

Benefits

• Enhances technician safety: Verifies instrument function without approaching energized conductors

• Improves confidence in measurements: Ensures testers and meters operate properly before performing live work

• Speeds up field workflows: Enables quick, repeatable voltage verification on the job site

• Supports compliance procedures: Ideal for facilities with strict electrical safety or TBT requirements
