Fluke PRV240 Voltage Indicator Proving Unit 240V AC/DC is a pocket-sized, battery-powered device designed to provide a steady, known live voltage for verifying the functionality of electrical test instruments before live measurements. Its compatibility with both alternating and direct current output ensures reliable instrument verification in various industrial, laboratory, and field environments.
The unit sources 240V AC or DC output and is compatible with both high and low impedance testers, offering broad instrument coverage to reduce unnecessary exposure risks during meter verification. Recessed contact activation enhances safety by preventing accidental contact, and a single LED indicator provides rapid confirmation of output voltage presence.
Powered by four AA alkaline batteries, the PRV240 can complete approximately 5,000 five-second test cycles per battery set, providing long-lasting operation ideal for industrial maintenance, commissioning checks, and on-site validation of measurement equipment. The magnetic hanging strap facilitates hands-free verification processes.
Operating environmental conditions range from -10 °C to +50 °C with defined humidity limits, and the unit is suitable for use up to 2,000 meters altitude. Under load conditions greater than 3 kΩ, the device supplies a reduced AC voltage to simulate responses for low-impedance instruments, ensuring accurate instrument response simulation.
Sources 240V AC or DC output for instrument verification under load. High compatibility with low and high impedance measuring devices. Recessed contacts for enhanced operator safety during testing. LED output indicator for quick voltage presence confirmation.
Battery operation delivers approximately 5,000 test cycles per set. Magnetic hanging strap supports hands-free usage. Compact and lightweight design for portability. Designed for electrical maintenance, installation commissioning, and industrial automation equipment validation.
This Fluke Proving Unit is essential for electrical professionals requiring safe, reliable testing of voltage indicators, multimeters, clamp meters, and two-pole testers. Its design enables efficient pre-checks and field verification to ensure precise electrical measurements and system safety.
