The BM5200 is turned on by rotating the main range switch to
insulation test, voltage test or setup function.
The rear panel indicates polarity of test sockets and -, + and G
(Guard). The negative (-) terminal is at 0 V and positive (+)
terminal is at test voltage (up to 5000 V DC).

Before switching on the BM5200 the test leads should be connected
to the instrument.
There are three test terminals , - and G. These terminals
are designed to accept only the test leads supplied. Shutters across
the terminals prevent accidental ingress of dirt and other objects.
Test lead plugs interlock with the shutters and are released by
rotating the test lead plug a quarter turn.
After testing the charge present on the terminals due to internal
capacitance is fully discharged within 10 seconds of completion of
the test. You should be aware that it will take longer to discharge
external reactive loads.
