Before switching on the BM5200 the test leads should be
connected to the instrument.
There are three test terminals marked +, - 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 leads lock in the terminals to prevent accidental removal
during a test, rotate the plug until the locking action is engaged.
Terminal plugs can be removed by rotating through a quarter turn.
At the end of a test ensure that the voltage has decreased to a
safe value, i.e. <50 V, before removing the test leads. Reactive
loads may take some time to dissipate stored energy through the
instrument's internal discharge resistors.
