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.
