Key Features:
The Fluke PRV240 Proving Unit provides a safe and convenient way to verify the operation of electrical test instruments before and after voltage testing. Fluke designed this compact, battery-powered device to support Test Before Touch (TBT) procedures and help reduce exposure to electrical hazards.
The PRV240 generates a stable 240 V AC or DC output, allowing technicians to confirm that multimeters, clamp meters, and two-pole testers operate correctly before performing live measurements. As a result, users can verify instrument functionality without relying on a known live source.
The unit works with both high-impedance and low-impedance test instruments. In addition, recessed output contacts help prevent accidental contact and improve user safety during verification procedures.
A single LED indicator clearly shows when output voltage is present. Therefore, technicians can quickly confirm proper operation with minimal setup and training.
Its pocket-sized design weighs only 0.23 kg and includes a TPAK magnetic hanging strap for convenient hands-free use. Furthermore, four AA batteries provide up to 5,000 test cycles, reducing maintenance requirements and downtime.
The PRV240 complies with IEC 61010-1 and IEC 61010-2-030 safety standards, making it suitable for professional electrical testing environments. Consequently, it offers a practical solution for verifying test equipment and supporting safe electrical work practices.
