Notes on Safety
This device is designed to comply with IEC 61010 Safety Standards, and
4/15
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 precautions:
Never attach the clamp to a circuit that operates at more than the maximum rated
voltage to earth.
For safety’s sake,avoid clamping around bare conductors,while clamping or
measuring.
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 earthing 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.
1. 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.
2. 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.
3. Read and observe all warnings and precautions relating to electrical
WARNING
5/15
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.
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.
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.
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.

Description of Probe Parts
1）CP5300
7/15
1、Sensor head
This clamps the conductor being measured, and carries out the actual current
measurement. It 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 of shock, and therefore
great care should be exercised in handling it.
2、Opening lever
Operating lever for opening the sensor head. Always use this lever to open the
sensor head.
3、BNC output connector
Connect to the BNC input connector of the oscilloscope. The output of the
current probe is terminated internally. You must select the input impedance of
the oscilloscope to be 1 MΩ in order to make accurate measurements. If the
oscilloscope you are using does not have a 1 MΩ input impedance setting you
can purchase 50 Ω to 1 MΩ adapter.
4、Power indicator LED
When the power adapter is plugged ,the green LED lights.
8/15
5、Overload indicator LED
When the current measured exceed the range,the red LED lights and the buzzer
alarms.
6、Degauss AutoZero indicator LED
When the key(Degauss AutoZero) pressed, this green LED lights. If
degaussing succeed,the buzzer well make double short sound. If degaussing
failed,the buzzer will make a long sound.
7、Range indicator LED
The green LED indicates the selected range.
8、Degauss AutoZero Key
When the key is pressed, the probe will be degaussing and AutoZero,about 5
secs.
9、Range selected Key
When the key is pressed, the probe will switch the range.
The CP5050 has two ranges(30A and 5A).The Current Transfer Ratio is 0.1V/A
and 1V/A.
The CP5300 has two ranges(150Aand 30A).The Current Transfer Ratio is
0.01V/A and 0.1V/A.
10﹑Offset (Up)Key
When the key is pressed, the offset increased.
11﹑Offset (Down)Key
When the key is pressed, the offset decreased.
12﹑Power plug
Connect this to the power adapter (DC 12V/1.2A).
13﹑Coarse adjustment trimmer
This adjustment should only be carried out if the probe offset is outside the
range of the zero adjustment dial.
