Operating Precautions

DANGER
To avoid short circuits and potentially life-
threatening hazards, never attach the clamp to
a circuit that operates at more than 600 Vrms.
The maximum rated voltage to earth is 600
Vrms. Attempting to measure voltage in excess
of the maximum rated voltage to earth could
destroy the instrument and result in personal
injury or death.
This instrument should only be connected to
the secondary side of a breaker, so the breaker
can prevent an accident if a short circuit
occurs. Connections should never be made to
the primary side of a breaker, because
unrestricted current flow could cause a serious
accident if a short circuit occurs.
To avoid electric shock, do not touch the
portion beyond the protective barrier during
use.
Never apply voltage to the test leads when the
Resistance measurement, Continuity Check
modes are selected. Doing so may damage the
instrument and result in personal injury.
To avoid electrical accidents, remove power
from the circuit before measuring.
Operating Precautions
Follow these precautions to ensure safe operation
and to obtain the full benefits of the various
functions.
