Description of Parts
1 Open/Close Lever
This lever opens and closes the sensor head. Always use this lever when
opening and closing the sensor head.
2 Sensor Head
The sensor head clamp is positioned around the conductor under
measurement to detect current. It is a precision-assembled component
consisting of various parts including plastic molded parts, a ferrite core, and a
Hall element. Take proper care when handling the probe to avoid damage as
a result of sudden sharp changes in ambient temperature, mechanical stress,
or physical shocks.
3 Demagnetization Switch (DEMAG)
This switch demagnetizes the core which can become magnetized when
turning the power ON or OFF, or when applying excessive input. You must
always use this switch prior to performing measurement. The time required
for demagnetization is approximately one second. During demagnetization, a
degaussing waveform is output.
4 Zero Adjust Dial (ZERO ADJ)
The zero adjust dial lets you compensate for effects including the probe’s
offset voltage and temperature drift. Before performing measurement,
demagnetize the probe then carry out zero adjustment.
5 Coarse Adjustment Trimmer
This is used only when zero adjustment cannot be performed using the zero
adjust dial alone.
6 Output Terminal
This terminal is connected to a waveform measuring instrument (of 0.1 V/A,
input impedance 1 MΩ) and outputs the current waveform of the conductor
under measurement at a constant rate. The terminal connects to the BNC
input terminal of the waveform observation instrument.
7 Power Plug
Connect the power plug to the receptacle on the power supply (model 701934
or 700938) to supply power to the sensor and terminator.
Note
• The output from this probe is terminated internally. Use the probe with a waveform
measuring instrument of high input impedance. Accurate measurement cannot be
obtained at an input impedance of 50 Ω.
• When using an input terminal other than the BNC terminal (for example via a
BNC-to-banana plug or other adapter), make sure the polarity of the input terminal
is correct.
• Turn the connector until it clicks into place, and confirm that it is securely locked.
• To adjust the coarse adjustment trimmer, use a non-metallic flat-blade screwdriver
whose thickness is 0.4 mm, width is 1.8 mm, and length is 10 mm or longer.
• Do not press or turn the coarse adjustment trimmer by force using a screwdriver.
Doing so may damage the component.

Operating Procedure
Handling Precautions
WARNING
• Do not clamp bare conductors to avoid short circuits or personal injury
when the sensor head is open or measuring.
• Be careful not to damage the insulation surface of the conductor under
measurement.
• Do not short-circuit between the two measurement lines with the metal
part of the sensor unit. It may lead to a serious accident such as the
occurrence of an arc.
• Connect the power supply to the probe power terminal (option) of a
waveform measuring instrument such as Yokogawa DL/DLM series, or
use the power supply 701934 or 700938.
• Be careful of electric shock when connecting the probe to the device
under measurement.
• Read and observe the safety precautions of the instruments to be
connected to.
• To avoid electric shock, do not get the instrument wet or use it with wet
hands.

IM 701933-01E
Preparing for Measurement
CAUTION
When using a 701933 current probe, it may not be possible to use multiple
active probes at the same time with the 701934, 700938 power supply,
or the probe power supply from a YOKOGAWA waveform measuring
instrument. Make sure that the total current consumption of each active
probe does not exceed the current specifications of the probe power
supply. The current consumption of the probe depends on the measured
current (refer to the figure below).
See the following YOKOGAWA website for the usage limitations for each
measuring instrument.

1. Prepare the probe, a power supply 701934/700938, and a waveform
measuring instrument such as a digital oscilloscope or recorder.
2. Turn the power switch OFF, then connect the power cord.
3. Connect the power plug of the 701933 you are using to a power
receptacle on the 701934/700938.
4. Turn ON the power switch to the 701934/700938, and confirm that the
power indicator on the front panel illuminates.
Note
The output from this probe is terminated internally. Use the probe with a waveform
measuring instrument of high input impedance. Accurate measurement cannot be
obtained at an input impedance of 50 Ω.

14 IM 701933-01E
Demagnetization and Zero Adjustment
CAUTION
• When unplugging the output terminal, always release the lock first, then pull the
terminal out while holding the connector. Damage can result if you forcibly pull the
terminal without releasing the lock, or pull by the cable instead of the connector.
• When using an input terminal other than a BNC terminal, make sure the polarity
of the input terminal is correct.
• Do not demagnetize the probe while the clamp is positioned around the
conductor under measurement. The demagnetization procedure can inject
current into the conductor under measurement, possibly resulting in damage to
connected components. For the same reason, make sure that the probe clamp
is not positioned around a conductor under measurement when supplying power
to the 701933. A demagnetizing waveform can be generated when power is
supplied.
1. Ground the input of the waveform observation instrument and adjust the
trace to the zero position.
2. Set the input coupling of the waveform measuring instrument to DC.
3. Connect the output terminal of the 701933 to the input terminal of the
waveform observation instrument. Turn the connector until it clicks into
place, and confirm that it is securely locked.
4. Without positioning the probe clamp around the conductor under
measurement, press the open/close lever until the unlocked indicator
goes out, then confirm that the sensor head is securely closed.
5. Press the demagnetization switch (DEMAG) on the terminator.
6. Turn the zero adjust dial on the terminator to adjust the trace to the zero
position.
7. If you are unable to adjust the trace to zero in the step above, turn the
coarse adjustment trimmer until the trace comes within a range that can
be zeroed using the zero adjust dial.
Note
• The output from this probe is terminated internally. Use the probe with a waveform
measuring instrument of high input impedance. Accurate measurement cannot be
obtained at an input impedance of 50 Ω.
• Oscillation may occur when you execute DEMAG, but this has no effect on
measurements.
• The positive side of the waveform that is generated when you execute DEMAG may
not be symmetrical to the negative side, but this has no effect on measurements.

15
IM 701933-01E
Performing Measurement
CAUTION
• The maximum continuous input range is determined from the rise in
temperature resulting from self-heating during measurement. Do not
input currents exceeding this range. Doing so can cause damage.
• The maximum continuous input range differs depending on the frequency
of the measured current (see page 15, “Product Specifications”).
• If a current exceeding the maximum continuous input range is input the
sensor will heat up, triggering the probe’s internal protection function
which can interfere with normal output. Discontinue input immediately
(remove the sensor from the conductor under measurement, or set the
input current to zero). A sufficient cooling off period must be given until
normal operation is restored.
• Heat generated by an input current whose frequency is 1 kHz or higher
is mainly due to self-heating of the sensor head. In this case, the
protection function is not activated. Therefore, be careful of burns, short
circuits, and other accidents or sensor damage and the like caused by
the temperature increase.
• The overcurrent protection function may activate under high
temperatures, resulting in measured currents at or below the maximum
continuous input range.
• If a current exceeding the maximum continuous input range is input
continuously, the protection function can be activated repeatedly,
potentially causing damage to the probe.
• Product specifications showing the maximum continuous input range
also indicate a maximum peak current value of 50 Apeak, non-
continuous. This shows that the upper limit of the waveform response is
50 Apeak. Ensure that the current (RMS) does not exceed the maximum
continuous input range.
• When opening the sensor head, always use the open/close lever. If you
press the Upper core while the sensor head is locked, the open/close
mechanism can be damaged.
• Do not apply force to the sensor head in the direction indicated in the
figure below.
Locked
Upper core
Do not press
• To maintain the probe accuracy within the specifications and to verify
that correct measurement results are being obtained, periodic calibration
is necessary. The calibration period varies depending on your operating
environment and the frequency of use. We recommend that you set
a calibration period according to the frequency of use and ask us to
calibrate it periodically.
1. Perform all safety checks, and ensure that the above-mentioned
preparations for measurement have been taken.

16 IM 701933-01E
2. Pull the open/close lever to open the sensor head.
3. Orient the probe so that the current direction arrow on the tip of the
sensor points in the same direction as the flow of current in the conductor
under measurement. Position the probe clamp around the conductor
under measurement so that the conductor is centered in the clamp hole.
4. Press the open/close lever until the unlocked indicator goes out, then
confirm that the open/close lever is securely locked and that the sensor
head is securely closed.
5. You can now perform observation of the current waveform on the
waveform measuring instrument. The output voltage rate of the 701933
is 0.1 V/A. Convert the voltage sensitivity on the waveform observation
instrument to current sensitivity. For example, if the waveform observation
instrument’s voltage sensitivity is 10 mV/DIV, the current sensitivity would
be 100 mA/DIV.
Note
• The output from this probe is terminated internally. Use the probe with a waveform
measuring instrument having an input impedance of 1 MΩ or more.
• Immediately after turning the power ON, the probe may experience a large
offset drift due to self-heating, but this will mostly stabilize after approximately 30
minutes.
• Please note that during continuous measurement, the offset voltage can drift
depending on ambient temperature and other factors.
• In rare instances, connecting the power plug to a power supply that is ON can
cause oscillations, but malfunctions will not occur. If this occurs, opening and
closing the sensor head using the open/close lever will stop the oscillations and
restore normal functioning.
• Resonance can be generated depending on the frequency of the measured
current. This will not affect measurement.
• The position of the conductor under measurement within the clamp hole can affect
measurement. Keep the conductor in the center of the clamp hole.
• During measurement, press the open/close lever until the unlocked indicator goes
out, then confirm that the lever is securely locked and that the sensor head is
securely closed. Accurate measurements cannot be obtained if the sensor head is
not securely closed.
• In the high frequency domain, positioning the probe clamp on the high side of the
circuit can introduce common mode noise. As necessary, limit the bandwidth of
the waveform observation instrument, or position the probe clamp on the low side.

• Accurate measurements may not be possible if operated within close proximity to
strong magnetic fields such as those produced by transformers, circuits with large
currents, and wireless devices.
