Note 1
⋅ Do not place any unclamped conductor with an electric
current of a frequency of 10 kHz or more near the sensor
head.
Current flowing in the conductor 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,
electric currents in both sides will heat up the wires and
raise the temperature, thereby causing damage to the
sensor.
