Fluke PRV240 Proving Unit, Validate Test Tool Functionality Outside of Hazardous Zones, Supplies 240 V Both DC and AC, Compatible with Both High or Low Impedance Test Tools

The Fluke PRV240 Proving Unit is a portable, pocket-sized, battery-powered voltage source. It is unique because it sources stable AC and DC voltages for both LoZ and HiZ instruments. The Fluke PRV240 provides a safe method to verify that your electrical test tool is operating properly before and after you conduct any live tests. The concept of "Test Before Touch" (TBT" involved testing your meter against a known live source before and after the actual measurement. This sequence verifies that your test tool is operating properly through the actual measurement.

Features:
• Sources both AC and DC steady-state voltage - supplies 240V DC/AC
• Voltage sourced through recessed contacts that are activated when tested probes are insterted to avoid accidental contact
• Includes TPAK hanging strap, four AA batteries and instruction sheet
• Compatible with high impedance or low impedance multimeters, clamp meters or two pole testers
• Long battery life - 5000 tests per set of four AA batteries
