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 test 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 Trimmer
DLM series and other digital oscilloscopes utilize an automatic zero
adjustmentfunction.Normally,thezeroadjustmenttrimmerisnotusedforthe
adjustment.However,iftheresidualoffsetexceedstheautomaticadjustment
rangeandautomaticzeroadjustmentfails,youcanturnthetrimmertocarry
outthezeroadjustment.Thiscompensatesfortheeffectsoftheprobe’s
offset voltage, temperature drift, and other phenomena. Before performing
measurement,demagnetizetheprobethencarryoutzeroadjustment(see
page 4).
 • AdjustmentwiththeZeroAdjustTrimmer
 Youcanadjusttheoffsetvoltageusinganappropriatedriverasdescribed
below.Useadriverthatfitstheadjustmentgroove.Usingadriverwith
a large grip or a small head, or applying excessive force can result in
damagetotheadjustmentturnstoporgrooves.
 • ExampleDriverBitDimensions(Referencevalue)

5. Probe Interface
The point of connection to the input of the digital oscilloscope. Outputs the
measured current waveform at a constant rate (0.1 V/A, in combination with
1MΩimpedance).TheoutputterminalisaBNCconnector.Connecttoa
digital oscilloscope that supports the YOKOGAWA probe interface.

3
IM 701928-01E
6. Interface Spring Pins
When the probe interface is connected, it touches the pad on the interface
board of the oscilloscope. The probe’s power and offset voltage are supplied
through this interface component. It also automatically recognizes the probe
type.
7. Latch Release Lever
Release the lock when connecting the probe interface to the oscilloscope
input.
Operating Procedures
Usage Precautions
WARNING
If the waveform measuring instrument to be connected to the output
terminal (BNC) of this probe has other measuring terminals, the probe’s
connection terminals and internal circuits may become hazardous live
depending on the types of devices that are connected to the instrument’s
measuring terminals.
To avoid this, note the following:
• Ensurethatbasicinsulationequivalenttothatofthecircuitundertest
in terms of measurement category, operational voltage, and pollution
degree is used between the measuring terminal to which the probe is
connected and other measuring terminals.
• Ifthebasicinsulationacrossmeasuringterminalsdoesnotmeetthis
requirement, do not apply an input exceeding the safety voltage level to
any of the other measuring terminals.
• Alwaysgroundthemeasuringinstrument.
• Takecaretoavoidelectricshockwheneverconnectingtheprobe
to a measuring terminal. Also, never disconnect the probe from the
measuring instrument while the probe is connected to the circuit under
test.
• Beforeconnectingtheprobetothecircuitundertest,confirmthatthe
measuring instrument is correctly grounded, and that the probe interface
is properly connected to the measuring instrument’s input.
• Makesuretoreadallsafetyprecautionsandwarningssuchas
information concerning electric shock for any instruments to which the
probe will be connected.
CAUTION
To clean the instrument, wipe using a soft cloth with a small amount of
water or mild detergent. Never use detergents that contain benzine,
alcohol, acetone, ethyl compounds, ketones, thinner, or gasoline as
deformation or discoloration can result.

4IM 701928-01E
Preparing for Measurement
CAUTION
• Whenusingthisprobe,restrictionsonthemaximumallowablepower
supply current of the DLM series’ YOKOGAWA probe interface may
prohibit using multiple active probes simultaneously depending on the
current being measured.
• Theprobe’scurrentconsumptiondependsonthecurrentbeing
measured. Make sure that the total current consumption of each of the
active probes does not exceed the probe power’s maximum allowable
current. See the user’s manual of the digital oscilloscope being used for
the probe power’s maximum allowable current. For this probe’s current
consumption, see page 10, “Measured Current Values and Current
Consumption (Typical).”
1. Set up the probe and a DLM series or other digital oscilloscope with the
YOKOGAWA probe interface.
2. Before measurement, insert the probe interface completely into the
input of the oscilloscope and confirm that a secure connection has
been established between the BNC connector and interface pins. When
inserted, you will hear a click as the latch closes, indicating that the
connection has been made.
Warm Up
Immediately after connecting the probe, heat emitted from the probe itself
causes the output offset voltage to drift. After applying power, the probe should
nearly stabilize about thirty minutes after connecting it. Before using the probe,
allow it to warm up for at least thirty minutes.
Demagnetization and Zero Adjustment
CAUTION
• Whenremovingtheprobefromtheoscilloscope,besuretoreleasethe
lock first, then pull out the probe by the connector. The probe interface
can be damaged if you pull forcibly without releasing the lock, or if you
pull by the cable.
• Donotdemagnetizetheprobewhiletheclampispositionedaroundthe
conductorundertest.Thedemagnetizationprocedurecaninjectcurrent
into the conductor under test, possibly resulting in damage to connected
components. For the same reason, make sure that the probe clamp
is not positioned around a conductor under test when connecting this
probe to the oscilloscope. A demagnetizing waveform can be generated
when power is supplied.

5
IM 701928-01E
1. Connect the probe’s output terminal to the input terminal of the digital
oscilloscope.
2. Without positioning the probe clamp around the conductor under test,
press the open/close lever until the unlocked indicator goes out, then
confirm that the sensor head is securely closed.
Demagnetization
3. Press the demagnetization switch (DEMAG) on the probe interface.
Note
• 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.
Zero Adjustment (Residual Offset Adjustment)
4. Comfirm the input coupling of the digital oscilloscope to DC. For
instructions on selecting the input coupling, see the user’s manual of the
digital oscilloscope.
5. Select the menu on the digital oscilloscope for performing automatic
zeroadjustmentonthecurrentprobetoadjusttheresidualoffset.For
instructionsonperformingautomaticzeroadjustment,seetheuser’s
manual of the digital oscilloscope.
6. Ifanerrormessageappearsduringstep5andyouareunabletoadjust
thetracetotheGNDlevel,turnthezeroadjustmenttrimmersothatthe
trace approaches the GND level, then repeat step 5.
Note
Ifthedigitaloscilloscopesupportsthecurrentprobe’sautomaticadjustment
function*,performautomaticzeroadjustmentonthedigitaloscilloscope.However,
iftheresidualoffsetexceedstheautomaticadjustmentrangeandautomaticzero
adjustmentfails,turnthetrimmertocarryoutthezeroadjustment.Uponshipment
fromthefactory,thezeroadjustmenttrimmerisadjustedsothatitcanbeusedfor
automaticzeroadjustmentina23°Cenvironmentaftera30minutewarm-up.
* With the DL9000 series, the function is supported with firmware version 3.66 or
later.

6IM 701928-01E
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 9, “Product Specifications”).
• Ifacurrentexceedingthemaximumcontinuousinputrange,heatfrom
the input the sensor will trigger the probe’s internal protection function
which will interfere with normal output. If this occurs, immediately
remove the sensor from the conductor under test, 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.
• Continuousinputexceedingthemaximumcontinuousinputrange,or
continual activation of the protection function can damage 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.

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.

IM 701928-01E
1. Perform all safety checks, and ensure that the preparations for
measurement (see page 4) have been taken.
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 test. Position the probe clamp around the conductor under test 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. The current waveform can now be observed on the digital oscilloscope.
The output voltage rate of this probe is 0.1 V/A. For example, if the digital
oscilloscope’s voltage sensitivity is 10 mV/DIV, the current sensitivity
would be 100 mA/DIV.
Digital oscilloscopes that support the YOKOGAWA probe interface
automatically detect the probe and convert the display unit to current
sensitivity.
Note
• WhentheprobeisusedwithaDLMseriesorotherdigitaloscilloscopeequipped
with the YOKOGAWA probe interface, the probe sensitivity is automatically
detected by the digital oscilloscope. If not automatically detected by the digital
oscilloscope,settheinputimpedanceto1MΩ.
• IftheprobeisconnectedtothedigitaloscilloscopewhilethepowerisON,
oscillations may occur very occasionally but this does not indicate a malfunction.
If this occurs, opening and closing the sensor head with the open/close lever will
stop the oscillations and restore normal functioning.
• Resonantsoundcanbegenerateddependingonthefrequencyofthemeasured
current. This will not affect measurement.
• 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.
• Thepositionoftheconductorundertest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.
