WARNING
• When attaching voltage probes to or clamping a clamp-on probe on the circuit
under test, turn off power to the circuit under test.
It is very dangerous to connect or disconnect a voltage probe or clamp or
unclamp a clamp-on probe without turning off the circuit under test.
• Be sure to connect voltage probes to or clamp a clamp-on probe on the sec-
ondary side of the circuit under test, such as current limiters (circuit break-
ers). Should an accident such as a short occur, other circuits will be protected
by these circuit breakers.

arrows on the clamping
CT faces the correct
direction.
