The Megger MJ15 analogue 5 kV insulation tester is a completely self-contained instrument designed for high voltage insulation resistance testing in the maintenance and servicing of rotating plant machinery, transformers, switchgear and industrial installations.

Tests can be performed at 500 V, 1000V, 2500 V or 5000 V. Insulation measuring range is 100 kΩ to 20 GΩ and Infinity. Automatic discharge for capacitive circuits under test is provided and decaying voltage displayed.

Tests are initiated by pressing the ‘Test’ button (or by turning the MJ15 generator handle). Releasing the ‘Test’ button causes the instrument to default to ac/dc voltmeter mode, with a discharge resistor internally connected across the terminals. This feature will give decaying voltage indication following the testing of equipment possessing capacitance.

Normal power for the MJ15 is by low voltage, hand cranked, brushless a.c generator. Fitting the battery container supplied, with eight 1,5 V IEC LR6 cells gives the instrument a dual (independent) supply capability.

The instrument will operate in any position, but best results are achieved when the instrument is face up, on a firm level surface.
