The Megger BM15 (6410-919) is a compact 5 kV insulation tester. It is very simple to use and provides a quick and accurate reading of insulation resistance. The instrument uses an analog display with a maximum reading of 20 Gigaohms. The BM15 is powered by eight LR6 (AA) alkaline cells. Four test voltages are available at 500 V, 1 kV, 2.5 kV and 5 kV.
A bezel on the BM15 allows a scale plate overlay to be added with pass/fail bands for go/no go testing. This is particularly useful for less experienced users and enables a rapid decision to be made.
The BM15 Insulation Tester is built into a rugged case designed for outdoor use. Safety terminals suitable for locking connectors are used for connection to the test piece. An automatic discharge circuit eliminates the voltage on capacitive loads after a test. The decaying voltage can also be viewed on the scale.
The BM15 meets the IEC1010 safety specification and EMC specifications, and it is fully CE marked
