Megger MPU690 proving unit (1001-561)

• 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.
