Preface
First of all, thank you for purchasing our products, this instruction manual is the
description about the function, usage, operation attention points, etc. Before use, please
read the instructions carefully and use correctly.
Manual annotation will use the following symbols to distinguish.
 To prevent shortage and accident, the circuit under test should be below 600VAC.
 Do not test the naked conductor.
 Do not touch the conductor under test and the sensor head during testing.
 When the oscilloscope is connected with other test terminal, please pay attention to the following
points:
 Please use the basic insulation device with proper voltage and pollution range when connecting
the test terminals between CPL2000 and devices.
 Do not input voltage surpassing the safety range if the basic insulation of the test terminal does
not meet the requirement.
 Please refer to the matters need attention about electronic safety.
 Electric shock could occur if the machine or the user’hand is wet during testing.
 The sensor head is consisted of precision devices including magnetic core, hall component. The
drastic change of temperature or the external impact could damage the sensor so please avoid

In the case of wrong operation, the user risk injury. The content under this
mark records the relevant matters needing attention to avoid such dangers.
The user may suffer minor injuries and material damage with the wrong
operation. To avoid such situation, the matters under this mark need attention.
This symbol means it is harmful to the machine and human body; you must
strictly follow the instruction manual to operate.

vibration or strike during operation.
 CPL2000 is neither waterproof nor dustproof. Please do not use it in dusty or wet environment.
 The upper and lower touching surface of the sensor head is created by accurate grinding process.
Please try not to damage it or the function will be badly affected.
 The current probe has an inner square shape 9V battery. CPL2000 is highly power-consuming so
please use the alkaline battery that can last long.
 Comparatively large test error could occur when the power supply is low. When the battery voltage
is lower than 6.5V, the machine will notify the users by a low voltage alarm. Please change the
batteryASAP to ensure the accuracy of testing.

1.Summary
CPL2000 is a type of current probe that can test AC and DC simultaneously. The current under
test can reach maximum value 2000Arms, peak value 3000Apk, bandwidth 10 kHz (-3dB). With two
range selection (200A and 2000A optional), users can choose the proper range according to the current
value; with auto zero function, users can make use of CPL2000 easily, and the power and battery low
voltage alarm indication light and overload alarm buzzer equipped can notify the users fast. Also,
CPL2000 can be powered by battery or external power supply. Its standard BNC output port allows it to
connect with oscilloscope and other devices, including multi-meter by BNC to Double Banana plug.
CPL2000 is usually used in fields including power frequency measurement, motor drive and power
suppy.
2.Probe Parts Description
 Probe
 Power Switch
OFF：Probe is turned off and power supply is off.
ON：Probe is turned on and power supply is on
 Power Indication Light: Lighted green when power supply switch is ON.
 Low Power Indication Light: Lighted red when battery voltage is lower than 6.5V, please change
batteryASAP.
 Range Button: Range switching button
 Range Indication light: Indicating the current range selection. 2000A and 200Aoptional.
 Auto zero button: To test accurately, zero set the probe to prevent the environmental factors such
as earth magnetic field or temperature drift from affecting the result.

4.Operating Methods
 Set the CM of the oscilloscope to DC, oscilloscope input impedance to 1MΩ. To make number
reading easier, user can change the display unit of the oscilloscope from voltage to current. Set the
corresponding attenuation according to the situation, for example, for probe set 2000A (1mV/A),
oscilloscope should be 1000X, for probe set 200A (10mV/A), oscilloscope should be 100X. User can

connect the BNC output port of the probe and input terminal of the oscilloscope using the standard
BNC cable.
 Turn on the voltage switch, the indication light should be lighted green.
 Press the button to select the proper range according to the value of the current under test.
Attention: Different range corresponds to different attenuation ratio
 Press the auto zero button to realize zero set. The buzzer will buzz shortly for twice if auto zero set
successfully, or it will buzz for once, meaning auto zero set fails. One thing need attention is that, the
external magnetic field could have slight effect on the AC zero position of the probe, so user better
not move the probe after zero set complete.
 Open the clamp of the current probe and fix the conductor under test
Attention: there’s direction indication on the clamp, the same current direction will generate positive
output, and otherwise it will generate negative output.
 Properly set the vertical sensitivity of the oscilloscope to generate stable wave form. When
oscilloscope is set DC CM, user can observe both DC and AC component, but if there’s only AC CM,
onlyAC component will be seen.
