OVERVIEW
27
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.
When opening the sensor head of the probe, be
sure to operate with the opening lever. If an
upper core is forced to open, when the sensor
head is locked, the open-close mechanism can be
damaged.
NOTE
The output of this device is terminated internally.
Use a waveform measurement instrument with
an input impedance of at least 1 MΩ.
Immediately after powering on, this device may
be subject to an appreciable offset drift due to the
effect of self-heating. To counteract this, allow the
device to warm up for about 30 minutes before
carrying out measurement.
