Test unit, battery powered.

Introduction

This portable proving unit, the Fluke PRV240 Proving Unit from FLUKE, is a pocket-sized, battery-powered voltage source intended for verifying the functionality of measuring instruments. The Fluke PRV240 provides both AC and DC voltage and indicates the presence of output voltage with a single LED, making the unit easy to use when checking test equipment before measurements.

Features

• Stable voltage source: delivers 240 V AC RMS or DC ±10% at ≥ 1 MΩ load.
• Compatibility: can be used with both high-impedance and low-impedance instruments (LoZ and HiZ). For LoZ >3 kΩ, the unit typically delivers approx. 60 V AC (min. 50 V AC RMS).
• Visual indicator: single LED that illuminates when output voltage is present.
• Power source: powered by four AA alkaline batteries (NEDA 24 A / IEC LR03).
• Safety design: output through recessed contacts that activate when test probes are inserted.

Typical Applications

The Fluke PRV240 is used to verify the function of electrical test equipment before and after a measurement, in accordance with the "Test Before Touch" (TBT) principle. The unit provides a known voltage source, which allows verification that a multimeter or other two-pole test instrument is functioning correctly without exposing the operator to live circuits.
