Safe Probing
This device is designed to comply with Safety Standards and has been thoroughly
tested for safety prior to shipment. However, mishandling during use could result in
injury or death, as well as damage to the device. Be certain that you understand the
instructions and precautions in the manual before use. We disclaim any responsibility
for accidents or injuries not resulting directly from device defects.
Neverattach the clamp to a circuit that operates overthe maximum rated voltage
to earth.
Please avoid clamping around bare conductors during measurement.
While clamping and measuring, do not touch the clamp in front of the barrier or
the conductor being measured.
Be careful to avoid damaging the insulation surface while taking measurements.
Make sure that the waveform measuring equipment connected to this device's
output terminal ( BNC ) is equipped with a protective earthling with double-
insulation construction.
Donotallowthedevicetogetwet,anddonottakemeasurementswithwethands.
This may cause an electric shock.
If the waveform measuring instrument being connected to the output terminal
( BNC ) on this device is equipped with any other measurement terminals, take
the following precautions to ensure that the other instrument does not form a
bridge between the probe and any hazardous live part of a part.
Isolate the terminal to which the probe is connected from other terminals on the
measuring instrument using basic insulation conforming to the measurement
category, working voltage, and pollution degree requirements of the circuit being
tested.
If basic insulation requirements cannot be met between the terminal to which this
device is connected and other terminals of the measuring instrument, make sure
that the voltage input to the measurement terminal does not exceed the
Separated Extra-Low Voltage Earthed.
Read and observe all warnings and precautions relating toelectricalsafety for the
measuring instrument being connected to the probe.

Toavoiddamagetothedevice,protectitfromvibrationorshockduringtransport
and handling, and be especially careful to avoid dropping.
Do not store or use the device where it could be exposed to direct sunlight,high
temperature, humidity, or condensation. Under such conditions, the device may
be damaged and insulation may deteriorate so that it no longer meets
specifications.
Before using the device the first time, verify that it operates normally to ensure
thatthenodamageoccurredduringstorageorshipping.Ifyoufindanydamage,
contact your dealer or SIGLENT representative.
Thisdeviceisnotdesignedtobeentirelywater-ordust-proof.Toavoiddamage,
do not use it in a wet or dusty environment.
The sensor head is a precision assembly including a molded component, a
ferritecore,anda HallEffectelement.Itmaybedamagedifsubjectedtosudden
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 precision ground, and should be
treatedwithcare.Ifthesesurfacesarescratched,performancemaybeimpaired.
Foreign substances such as dust on the contact surfaces of the sensor head
can cause acoustic resonance and degrade measurement, so it should be
cleaned by gently wiping with a soft cloth.
To avoid damaging the sensor cable and power supply cable, do not bend or
pull the cables.
When the power is on, keep 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.
Do not place any un-clamped conductor with an electric current of a frequency
of10kHzormorenearthesensorhead.Currentflowingintheconductornearby
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 ,
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.
The maximum continuous input range is based on heat that is internally
generated during measurement. Never input current in excess of this level.
CAUTION

CP6000/CP4000
Current Probe Instructions 5
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.
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 belowthe rated continuous maximum.
Continuousinputofcurrentexceedingtheratedmaximumorrepeatedactivation
of the safety function may result in damage to the unit.
The probe is rated for maximum input under two conditions in addition to the
input maximums shown in the Specifications. These are (1) 30A peak for non-
continuous input and (2) 50A peak for pulse widths 10 µs. (1) indicates an upper
waveform response limit of 30A peak. Use the sensor at RMS current input
levels that are within the rated continuous maximums. (2) Indicates the upper
response limit for a single input pulse.
Whenopeningthesensorheadoftheprobe,besuretooperatewiththeopening
lever. If an upper core is forced to open when the sensor head is locked, the
open close mechanism can be damaged.

The output of this unit is terminated internally. Use an oscilloscope with an input
impedance of at least 1 MΩ.
Immediately after powering on the probe, the probe may be subject to an
appreciable offset drift due to the effect of self heating. To counteract this, allow
the probe to warm up for about 30 minutes before carrying outmeasurement.
When performing continuous measurements, it is necessary to be aware that
theoffsetvoltage drifts, depending on factors such as the ambient temperature.
Under certain circumstances, oscillation may occur if the probe is connected to
the 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, some sound maybe produced
by resonance, but has no effect on measurements.
The reading 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 a 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, an accurate measurement is not possible.
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.
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
waveformmeasuringinstrumentorclampontothelow-voltagesideofthecircuit.

Q&A
Does CP6000 series fit the oscilloscope of anybrand?
A: CP6000 series has standard BNC interface can be applied to the oscilloscope of
any brand. It is powered by standard adapter, independent of oscilloscope power, so it
is very easy to use.
Can CP6000 series product measure small current?
A: Yes. For now, the CP6000 series current probe has two optional ranges, and oneis
for small current. The current resolution of the CP6030(A) is 1mA. When measuring
smallcurrent,pleaseaccuratelyzerosetanddegaussingtheprobe,anddonotchange
theposition of the probe hand grip. To observe the waveform pleaseset the bandwidth
restriction of the oscilloscope to 20MHz to eliminate the interference of noise. When
measuringextremelysmallcurrent(afewmAforexample),onecouldmakea fewmore
loop of cable around the probe and divide the result with number of loop to obtain the
actual current value.
Any more tips?
A:
When measuring high frequency current, please do not let the current surpass
the value shown by the curve of max peak current vs frequency. The max
continuous current over the curve will burn the probe.
To measure accurately, please degauss and zero set the probe, and make
sure the probe is locked during the process.
Set the input impedance of the oscilloscope to 1MΩ(default)
Make sure the probe is locked during testing.
The probe should be away from the interference source like transformer. The
method to judge if the probe is interfered is to put the probe close to circuit
under test. IF there’s any output, there could be interference in the testing
environment because the probe is not on the circuit yet.
The current under test should not surpass the limit value of the probe.
Please always maintain your probe and do not use it in the humid environment
If there’s anything wrong with the probe, please set it back for repairing. If you
dismantled the device on your own, we won’t guarantee for repairing.
