Megger MPU690 Proving Unit

5 stepped nominal output voltages Automatic operation High output power suitable for test lamps Extended battery life Magnetic base Rugged case

Good practice requires that two pole voltage detectors are proved to be functioning correctly on a known voltage source, both before and after they have used to verify that a circuit is not live.

The Megger MPU690 proving unit provides a portable battery operated voltage source that can verify the correct functioning of a two pole voltage detectors.
