To avoid electrical shock, follow the precau-
tions below to ensure no dangerous voltage
from the power of the instrument being con-
nected to or its other measuring terminals
(those not connected to this device) is
impressed upon the 9754 CLAMP ON
NOISE SENSOR. If dangerous voltage is
impressed upon this device, dangerous volt-
age will be generated in its BNC connector
and inner circuitry, presenting an extreme
hazard.
• Only connect to instruments which are
constructed with double insulation and use
a protective earth.
• Confirm that basic insulation which meets
the measurement category, working volt-
age and pollution degree of the circuit
being tested, is used to isolate the other
measurement terminals of the instrument
being connected to.
If you are not sure basic insulation is used
between the terminals of the measurement
device, do not input voltage which exceeds
the Separated Extra-Low Voltage Earthed
(SELV-E) level into the other terminals of
the instrument.
• Observe all safety precautions of the
instrument you are using.
Refer to the following standards regarding
the meanings of underlined terms.
IEC 61010-1
