3. Making Measurements
Before using the probe, check that the system is safe and that the preparations described in Safe Probing.
 Have a visual inspection of the current probe of high frequency HCP8000 Series probes,
power supply, cable, and oscilloscope.
 The output of the current probe is terminated internally. Use a high impedance input to the measuring
instrument. Be sure to set the input impedance to 1 MΩbefore making measurements. Set the oscilloscope’s
input coupling to DC. With the oscilloscope input at ground, adjust the trace to the zero position. Connect the
probe’s output connector to the oscilloscope’s input connector.
 Connect the power supply to probe and the power indicator will light. Select suitable Range you want via the
Range Key.
 Ensure that the probe sensor is NOT clamped around any conductors. Slide the probe’s Opening Lever into the
LOCKED position as shown in Figure. Confirm that the sensor head is properly closed.
 Degaussing and Zero Setting
When the key is pressed, the probe will demagnetize the core and set the output to zero voltage if it has been
magnetized by switching the power on and off, or by an excessive input. Always carry out demagnetizing and
Zero Setting before measurement and without current in the clamp. The demagnetizing and Zero Setting
process takes about a few seconds. During demagnetizing and Zero Setting, a demagnetizing waveform is
output.
If degaussing and Zero Setting succeeds, the buzzer will make two short beeps. If degaussing and Zero Setting
failed, the buzzer will make a single sound, for one second.

Do not demagnetize while the conductor being measured is clamped. This could damage the components of the
circuit being measured. Also, check that the conductor being measured is not clamped when supplying power
to the current probe for the same reason. Demagnetized waveforms are generated when switching on the
supply.
 Measurement
Press the opening lever to open the sensor head.
Align the sensor so that the probe’s current direction indication corresponds to the direction of current
flow through the conductor to be measured. Also, align the clamp so that the conductor is in the center of
the sensor aperture.
Press the opening lever on the sensor head until the UNLOCK indication disappears. Check that the
opening lever is firmly locked, and the sensor head securely closed.
4. 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.
To avoid short circuits and potentially life-threatening hazards, follow these warnings and precautions:
 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 (BNC) is
equipped with a protective earthling with double-insulation 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 (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 to electrical safety for the measuring instrument
being connected to the probe.

 To avoid damage to the device, protect it from vibration or shock during transport 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 that the no damage occurred
during storage or shipping. If you find any damage, contact your dealer or CYBERTEK 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 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 precision ground, and should be treated with care. If these
surfaces are scratched, performance may be impaired.
 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 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 , 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 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 below the rated
continuous maximum.
 Continuous input of current exceeding the rated maximum or repeated activation 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)
CYBERTEK

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.
 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.
 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 out
measurement.
 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 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 waveform measuring instrument or clamp onto the low-
voltage side of the circuit.

7. Operating Method
 The output interface of this machine is set inside. When using the oscilloscope, please select high input
resistance (1MΩ). If the input resistance is 50Ω, the data will be incorrect.
 Please make sure the current measured doesn’t surpass the maximum current. The magnetic core will saturate.
The saturated magnetic core will neutralize the generate 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 the machine. But it will be
stabilized after about 30 min.
 Strong magnetic field like transformer, large circuit, high electricity like wireless will cause 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.
 Push the switch control pole all the way through until the unlock mark disappear. Please make sure the control
Note
CYBERTEK

pole is locked and the entire structure is closed. If the entire structure isn’t closed, the testing will go wrong.
 If you insert the high potential side of the circuit in high frequency domain, the result might be influenced by
the noise. If it’s necessary, please limit the waveform observer’s frequency domain or insert the low potential
side of the circuit.
 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.
 When putting in the output terminal other than BNC terminal, please be careful for the polarity of the terminal.
 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 of the current under test. The
probe will be damaged when operate under overcharged current .
 When the input current continuously surpasses the maximum input range, the self-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 even when the continuous current
under test is below the max input.
 When the connect input surpass the max input range current and activate the protection 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.
7.1 Preparation before testing
 Prepare the high frequency current probe HCP8000 series, adapter and oscilloscope
 Power up the HCP8000 probe and the green LED power indicator will be lighted.
 Set the oscilloscope: Ground the measuring mode, zero set the oscilloscope and turn the oscilloscope mode
to DC mode.
 Choose the proper range according to the current under test. The default setting of the probe is large current
range
7.2 Degaussing and Zero setting
 Connect the HCP8000 with oscilloscope (Make sure the input impedance of the oscilloscope is 1MΩ)
 Lock the probe until the UNLOCK symbol disappear.
 Press the button to degauss and zero set. There will be beeping as success indication after 6s
7.3 Measuring method
 Confirm the previous steps
 Pull the switch control pole of the sensor, open the head of the sensor and make the current direction mark in

front of the sensor accordance with the current under test, and put the conductor under test in the middle of
the sensor.
 Push the switch control pole of the sensor until the UNLOCK mark disappear. Lock the probe, make sure the
entire part is closed, and then observe the waveform under test. Utilize the current transfer ratio to transform
the voltage sensibility into current sensibility. For instance, the ratio of HCP8030 is 0.1V/A (30A range), and
then, when the voltage sensibility of the waveform monitor is 10mV/div, the current sensibility is 100mA/div.

9. Q&A
9.1 Does HCP8000 series fit the oscilloscope of any brand?
A: HCP8000 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.
9.2 Can HCP8000 series product measure small current?
A: Yes. For now, the HCP8000 series current probe has two optional ranges, and one is for small current. The
current resolution of the HCP8030(D) is 1mA. 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 20MHz to eliminate the interference of noise. When
measuring extremely small current (a few mAfor example), one could make a few more loop of cable around
the probe and divide the result with number of loop to obtain the actual current value.
9.3 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.
