International electrical symbols used are explained below.
The terms "Isolated" or "Electrically floating" are used in
this manual to indicate a measurement in which the
ScopeMeter test tool COM (common, also called ground) is
connected to a voltage different from earth ground. The
term "Grounded" is used in this manual to indicate a
measurement in which the ScopeMeter test tool COM
(common) is connected to an earth ground potential.
The ScopeMeter test tool COM (common) inputs (red
INPUT A BNC shield, grey INPUT B BNC shield, and black
4-mm banana jack) are connected internally via self-
recovering fault protection. The input connectors have no
exposed metal and are fully insulated to protect against
electrical shock. The black 4-mm banana jack COM
(common) can be connected to a voltage above earth
ground for isolated (electrically floating) measurements
and is rated up to 600V rms above earth ground.
