Used in conjunction with a two-pole voltage tester, Megger's new MPU690 proving unit provides a fast and dependable method of confirming that circuits are dead prior to carrying out work on them.
The new proving unit features time-saving automatic operation and its high output power makes it suitable for use with lamp type voltage testers as well as with more modern units.
To ensure safety, when a two-pole voltage tester is used to confirm that a circuit is dead, the correct operation of the tester itself must be verified using a known live voltage source both before and after checking the circuit. Often, however, no suitable voltage source is available. The new MPU690 provides a convenient and reliable alternative.
