1. Introduction
The CP2100 series is a current probe that can measure both DC and AC. It is
a split-type design that is small and beautiful. It uses a standard BNC
interface for oscilloscopes or a multi-connector for adapters. The maximum
current that can be measured is 100Apk
(70Arms); it is divided into 2 models, CP2100A measurable bandwidth range
is DC~800KHz, CP2100B measurable bandwidth range is DC~2.5MHz,The
CP2100 series current probe has two optional ranges: 10A and 100A . With
automatic and manual zero adjustment, USB power supply, no additional
power supply, making measurement more convenient. Often used in motor
drive, power frequency, inverter, power supply, avionics and other fields.

3. Instructions：
1.ConnecttheBNCofthecurrentprobetotheoscilloscope(orotherinstrument)
andconnecttheUSBcabletopowerthecurrent probe.
2.According to the current, select the appropriate range on the probe, the
corresponding button light turns green.
3.Adjust the oscilloscope settings: input impedance 1MΩ; Select current or
set display unit as A; Set the probe attenuation multiplier of the corresponding
channel. If the probe is 100A(0.01V/A), the oscilloscope should be 100X, if
the probe is 10A(0.1V/A), oscilloscope is 10X.
4.Press the auto zero button to realize the auto zero adjustment of the
probe. After the zero adjustment is successful, the buzzer will beep for
once. Otherwise, the “beep” sound will be 3, indicating that the zero
adjustment fails; The external magnetic field may have a slight influence
on the DC zero of the probe. After the zero adjustment is completed,
please do not move it in a large range.
5. Open the clamp of the current probe to clamp the conductor under test
according to the direction indicated by the clamp head. Note: If the
measured current flow direction is opposite to the direction indicated by
the clamp head, the output is negative.
6. Adjust the oscilloscope to get the best waveform.
Note: When the current exceeds the range, the buzzer will sound for a long
time and the button light will flash.
5. Maintenance
During the product warranty period and under normal use, the company
will be responsible for free maintenance due to the failure of the product
itself due to quality problems.
Please keep the product as dry, clean and tidy. If there is dirt, use a soft
cloth or sponge with alcohol to remove dirt. Do not use water.
In order to ensure the performance of the product, it is recommended to
conduct an inspection or calibration once a year.
