Fluke PRV240FS proving unit
The PRV240FS is a portable voltage source used to verify that a T6 electrical tester or another high-impedance instrument is responding correctly before performing actual measurements. It provides a stable 240 V AC or DC to the FieldSense jaw or to the recessed test contact points for probes, allowing for a quick functional check without having to access a live installation.
This is especially relevant when working where you want to ensure that the measuring instrument is functioning correctly before proceeding with further tests. In practice, this means you get a known reference signal to check the instrument against. This provides a simple way to perform "test before touch" when working safely and systematically with electrical measurements.
The unit is battery-powered and has clear LED indicators showing when there is an output and when the FieldSense and probe measurement functions are active. With its simple mode switch, it is quick to use in the field and is small enough to be easily carried in a toolbox.
It is suitable for tasks involving T6 testers, multimeters, or other high-impedance instruments, where it is important to be able to verify the measuring instrument on a known voltage source before measuring on the system.
