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
drawings below), 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.
