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.
