Do not place any unclamped
conductor with an electric cur-
rent of a frequency of 10 kHz
or more near the sensor head.
Current flowing in the conduc-
tor nearby may heat up the
sensor head and cause its
temperature to rise, leading to
damage to the sensor. For example, when one side
of a go-and-return conductor is clamped and the
other side is also placed near the sensor head as
shown in the diagram, even if the electric current is
lower than the consecutive maximum current, elec-
tric currents in both sides will heat up the wires and
raise the temperature, thereby causing damage to
the sensor.
2.2 Disconnecting the NOISE SENSOR
• To avoid damaging the device, always open the
clamp by using the slider.
• When disconnecting the BNC connector, be
sure to release the lock before pulling off the
connector. Forcibly pulling the connector without
releasing the lock, or pulling on the cable, can
damage the connector.
1.
Pull the sensor slider to open the
clamp.
2.
Remove the 9754 CLAMP ON NOISE
SENSOR from the conductor being
measured.
3.
Turn off the power on the instrument
being connected to.
