Safe ProbingThis device is designed to comply with Safety Standards and has been thoroughly
tested for safety prior to shipment. However, mishandling during use could result ininjury 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.

WARNING

Never attach the clamp to a circuit that operates over the 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 (SAPBUS) is equipped with a protective earthling with doubleinsulation construction.



Do not allow the device to get wet, and do not take measurements with wet hands.
This may cause an electric shock.



If the waveform measuring instrument being connected to the output terminal(SAPBUS) on this device is equipped with any other measurement terminals, takethe 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 themeasuring 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 thisdevice is connected and other terminals of the measuring instrument, make surethat the voltage input to the measurement terminal does not exceed the Separated

Current Probe Instructions

SCP5000

Extra-Low Voltage Earthed.


Read and observe all warnings and precautions relating to electrical safety for themeasuring instrument being connected to the probe.

CAUTION

To avoid damage to the device, protect it from vibration or shock during transportand handling, and be especially careful to avoid dropping.



Do not store or use the device where it could be exposed to direct sunlight, hightemperature, humidity, or condensation. Under such conditions, the device may bedamaged 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 thatthe no damage occurred during storage or shipping. If you find any damage, contact
your dealer or SIGLENT representative.

This device is not designed to be entirely water- or dust- proof. To avoid damage,
do not use it in a wet or dusty environment.

The sensor head is a precision assembly including a molded component, a ferritecore, 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 careshould be exercised in handling it.

The matching surfaces of the sensor head are precision ground, and should betreated with care. If these surfaces are scratched, performance may be impaired.

Foreign substances such as dust on the contact surfaces of the sensor head cancause acoustic resonance and degrade measurement, so it should be cleaned bygently 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 of

4Current Probe Instructions

SCP5000

10 kHz or more near the sensor head. Current flowing in the conductor nearby mayheat up the sensor head and cause its temperature to rise, leading to damage tothe 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. Exceeding the
rated level may result in damage to the probe.

The maximum continuous input range varies according to the frequency of thecurrent being measured.



If excess current is input, generated heat activates a built-in safety function thatblocks normal output. If this happens, remove the input immediately (remove thesensor 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 activationof 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) 30 A peak for non-continuous
input and (2) 50 A peak for pulse widths 10 µs. (1) indicates an upper waveform
response limit of 30 A peak. Use the sensor at RMS current input levels that arewithin the rated continuous maximums. (2) Indicates the upper response limit for asingle input pulse.

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.

SCP5000NOTE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 theprobe to warm up for about 30 minutes before carrying out measurement.

When performing continuous measurements, it is necessary to be aware that theoffset voltage drifts, depending on factors such as the ambient temperature.



Under certain circumstances, oscillation may occur if the probe is connected to thepower 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 byresonance, 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, push the opening lever of the sensor to lockthe probe 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 thehigh 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.

Operating Method
NoteThe output interface of this machine is set inside. When using the oscilloscope, it isautomatically configured with high input resistance (1 MΩ).



Please make sure the current measured doesn’t surpass the maximum current.
The magnetic core will saturate. The saturated magnetic core will neutralize thegenerate waveform during saturation. The overcharged inrush might cause
mistaken degaussing and need to be zero set again.

When power is connected, offset might occur because of the heat generated by themachine. But it will be stabilized after about 30 min.

Strong magnetic field like transformer, large circuit, high electricity like wireless willcause deviation.



The voltage might deviate because of the surrounding temperature, so please be
careful when testing sequentially.

The frequency of the current under test may cause resonance, but this won’t
influence the testing.

The position of conductor under test in the sensor will influence the result, so please
move the conductor under test into the center of the sensor.

Before measuring, push the opening lever to the lock state and confirm that the
opening lever is locked and the entire part is indeed closed. If the entire part is nottruly closed, it will not be able to measure normally.

SCP5000

Attention
When disconnecting the output terminal, please pull out the connector after
unlocking. The output terminal will be damaged if you force to drag the cable out
before unlocking.

The continuous maximum input range is the fixed value caused by the machine’s
operating heat. Please do not put in current higher than this value, or the device
will be damaged.



The continuous maximum input range will change according to the frequency ofthe current under test. The probe will be damaged when operate underovercharged current.

When the input current continuously surpasses the maximum input range, theself-protection will be activated by the heating of the sensor and cause wrong
output. Please stop the current input and wait for full cool down before next
operation.



The protection circuit will be mistakenly activated by the high temperature evenwhen the continuous current under test is below the max input.

When the connect input surpass the max input range current and activate theprotection function too often, the device may be damaged.



You must open the entire part through switch controller.

At the lock state, please do not press the entire part as shown below.

Preparation before testingPrepare the high frequency current probe SCP5000 series and oscilloscope.



Set the oscilloscope: Zero set the oscilloscope and turn the oscilloscope mode to
DC mode.



Choose the proper range according to the current under test.

Degaussing and Zero settingConnect the SCP5000 with oscilloscope (Make sure the input impedance of theoscilloscope is 1 MΩ).



Lock the probe and confirm that the opening lever is in lock state.

In the probe setting interface of the oscilloscope, click "Degauss / AutoZero" todegauss and zero set.

Measurement methods:
Confirm the previous steps.

Move the switch control pole of the sensor, open the head of the sensor and makethe current direction mark on the front end of the sensor consistent with the flow
direction of the measured current, and clamp the measured conductor in the
middle of the sensor head.

Q&A
Does SCP5000 series fit the oscilloscope of any brand?
A: SCP5000 series has standard SAPBUS interface can be applied to the oscilloscope
equipped with SAPBUS, and the probe is powered directly by the oscilloscope.

Can SCP5000 series product measure small current?
A: Yes. For now, the SCP5000 series current probe has two optional ranges, and one
is for small current. The current resolution of the SCP5030(A) is 1 mA. When measuring
small current, please accurately zero set and degaussing the probe, and do not change
the position of the probe hand grip. To observe the waveform please set the bandwidth
restriction of the oscilloscope to 20 MHz to eliminate the interference of noise. Whenmeasuring extremely small current (a few mA for example), one could make a few more
loop of cable around the probe and divide the result with number of loop to obtain theactual current value.

18

Current Probe Instructions

SCP5000

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 surethe probe is locked during the process.



Set the input impedance of the oscilloscope to 1 MΩ (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.
