10
PRECAUTIONS
• The sensor head is a precision assembly including
a molded component, a ferrite core, and a Hall
effect element. It may be damaged if subjected to
sudden changes in ambient temperature, or
mechanical strain or shock, and therefore great
care should be exercised in handling it.
• The matching surfaces of the sensor head are
precisely ground, and should be treated with care.
If these surfaces are scratched, performance may
be impaired.
• To avoid damaging the sensor cables, do not bend
or pull the sensor cable and power supply cable.
• To clean the device, wipe it gently with a soft cloth
moistened with water or mild detergent. Never
use solvents such as benzene, alcohol, acetone,
ether, ketones, thinners or gasoline, as they can
deform and discolor the case.
• When the power is on, keep the core section of the
sensor closed, except when clamping them onto
the conductor to be measured. The facing surface
of the core section can be scratched while it is
open.
• Keep the clamp jaws and core slits free from
foreign objects, which could interfere with
clamping action.
• Keep the sensor head closed when not in use, to
avoid accumulating dust or dirt on the mating core
surfaces, which could interfere with clamp
performance.
• Avoid stepping on or pinching the cable, which
could damage the cable insulation.
• Keep the cables well away from heat sources, as
bare conductors could be exposed if the insulation
melts.

This clamps the conductor being measured, and
carries out the actual current measurement. It is a
precision assembly including a molded
component, a ferrite core, and a Hall effect
element. It may be damaged if subjected to
sudden changes in ambient temperature, or
mechanical strain or shock, and therefore great
care should be exercised in handling it.
This demagnetizes the core if it has been
magnetized by switching the power on and off, or
by an excessive input. Always carry out
demagnetizing before measurement. The
demagnetizing process takes about one second.
During demagnetizing, a demagnetizing
waveform is output.
Use the zero adjustment dial to correct for the
effect of a voltage offset or temperature drift on
the device. When beginning measurement, after
demagnetizing always carry out zero adjustment.
Use this only when adjustment is not possible
within the range of the zero adjustment dial.Use a
nonconductive screwdriver (e.g. ceramic driver)
for adjustment.

Demagnetizing and Zero Adjustment
Procedure
CAUTION
1. With the waveform measurement instrument
input at ground, adjust the trace to the zero
position.
2. Set the input coupling of the waveform
measurement instrument to DC.
3. Connect the output connector of the GCP-530 or
GCP-1030 to the input connector of the
waveform measurement instrument. Turn the
collar until it clicks, and check that it is locked
securely.
• When disconnecting the output 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 terminator.
• If using BNC-banana plug adapters or similar to
connect to input terminals other than BNC
connectors, make sure the polarity is correct.
22
OVERVIEW
• Do not demagnetize while the GCP-530 or GCP-
1030 is clamping a conductor to be measured.
Demagnetizing causes current to flow into the
conductor, which may damage parts in the
circuit to be measured.
• Check that the conductor being measured is not
clamped when supplying power to the GCP-530
or GCP-1030 for the same reason. Demagnetized
waveforms are generated when supplying
electric power.
4. Without clamping the conductor to be
measured, press the opening lever until the
"UNLOCK" indication disappears, and check
that the sensor head is properly closed.
5. Press the demagnetizing switch (DEMAG) on
the terminator.
6. Turn the zero adjustment dial on the terminator,
to adjust the trace to the zero position.
7. If zero adjustment is not possible in step 6, turn
the coarse adjustment trimmer to bring the trace
within the range of adjustment by the zero
adjustment dial.

GCP Series User Manual
Measurement Procedure (Current Probe)
Procedure
1. Check that the system is safe, and that the
preparations described in the preceding section
have been carried out.
2. Pull the sensor opening lever, so that the sensor
head opens.
3. Align the sensor so that the current direction
indication corresponds to the direction of
current flow through the conductor to be
measured, and clamp so that the conductor is in
the center of the sensor aperture.
4. Press the opening lever on the sensor head until
the "UNLOCK" indication disappears, and check
that the opening lever is firmly locked and the
sensor head securely closed.
24
OVERVIEW
NOTE
Fig. 1
5. It is now possible to monitor the current
waveform. The output rate of the GCP-530 or
GCP is 0.1 V/A. The current sensitivity can be
derived from the voltage sensitivity of the
waveform measurement instrument. For
example, if the voltage sensitivity is
10mV/division, the current sensitivity is
100mA/division.
• When using the GCP-530 or GCP-1030, note that
two current probes may not be used
simultaneously with the GCP-425P POWER
SUPPLY, depending on the current to be
measured.
• The current consumption of current probes
depends on the current to be measured. Confirm
that the total current consumption of the current
probes do not exceed the rated output current of
the GCP-425P. See Fig. 1.

CAUTION
GCP Series User Manual
• The maximum continuous input range is based
on heat that is internally generated during
measurement. Never input current in excess of
this level. Exceeding the rated level may result in
damage to the probe.
• The maximum continuous input range varies
according to the frequency of the current being
measured. See the figures 3 on page 37 .
• If excess current is input, generated heat activates
a built-in safety function that blocks normal
output. If this happens, remove the input
immediately (remove the sensor from the
conductor being measured, or reduce the input
current to zero). Wait until the sensor has had
sufficient time to cool before resuming operation.
• Even if the input current does not exceed the
rated continuous maximum, continuous input for
an extended period of time may result in
activation of the safety circuit to prevent damage
resulting from heating of the sensor.
• At high ambient temperatures, the built-in safety
circuit may activate at current input levels below
the rated continuous maximum.
• Continuous input of current exceeding the rated
maximum or repeated safety circuit activation
will degrade performance of the safety circuit,
possibly resulting in damage to the device.
• The maximum input range is indicated by the
continuous maximum input range. It is also
indicated by another product specification
Maximum peak current: Noncontinuous 50 A
peak. This means that the upper limit of the
waveform response is 50 A peak. Make sure that
the input does not exceed the continuous
maximum input range in rms.
26
OVERVIEW
• 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.
27
GCP Series User Manual
• Depending on the measured current frequency,
however some sound may be produced by
resonance, it has no effect on measurements.
• When performing continuous measurements, it is
necessary to be aware that the offset voltage
drifts, depending on factors such as the ambient
temperature.
• Under certain circumstances, oscillation may
occur if the probe is connected to the GCP-206P
or GCP-425P POWER SUPPLY while the power
supply is on. This does not indicate a
malfunction. Oscillation can be stopped and
operation restored to normal by opening and
closing the sensor head.
• Depending on the measured current frequency,
however some sound may be produced by
resonance,it has no effect on measurement.
• The measurement may be affected by the position
within the clamp aperture of the conductor being
measured. The conductor should be in the center
of the clamp aperture.
• When carrying out measurement, press the
opening lever until the "UNLOCK" indication
disappears, and check that the sensor head is
properly closed. If the sensor head is not properly
closed, accurate measurement will not be
possible.
28
OVERVIEW
• At high frequencies, common mode noise may
affect measurements taken on the high voltage
side of circuits. If this occurs, reduce the
frequency range of the waveform measuring
instrument, or clamp onto the low voltage side of
the circuit, as appropriate.
• Accurate measurement may be impossible in
locations subject to strong external magnetic
fields, such as transformers and high-current
conductors, or in locations subject to strong
external electric fields, such as radio transmission
equipment.

electrical hazard.
• To avoid accidents, when using other
measurement devices with this one, observe the
usage precautions described for each device.
• To avoid electric shock or damage, when
connecting the current probe to a measurement
device that does not have its input terminals
isolated from the chassis, or to an device that
does not have it input terminals isolated from
one another and signals are applied to other
terminals, do not connect the grounding terminal
to any point that is not at ground potential.
Otherwise, if the grounding terminal is
connected to a point that is not at ground
potential, a short circuit will occur.

OVERVIEW
Measurement Procedure (Power supply)
NOTE
• Make sure the sum of the current consumption of
the connected current probe(s) does not exceed the
rated output current of the GCP-425P (See Fig.1)
on page 25.
• When using the GCP-425P with Model GCP-530 or
GCP-1030 Current Probe, in general only one
current probe may be connected. However,
depending on the current level of the object under
test, two current probes may be connected
simultaneously.
• The current consumption of a current probe is
dependent upon the current level of the object
under test.
