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 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

(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

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.

Summary

The CP5000 series uses a combination of Hall effect and transformer technology
which enables measurements to be made on DC, AC and impulse currents. It’s key
features include highly accurate current measurements﹑wide bandwidth﹑easy current
