1. Summary
CPL8100A/B is a kind of current probe that can measure both DC and AC current up
to 100A (70.7Arms). The band width of CPL8100A is 600 kHz (-3dB), and the band width of
CPL8100B is 2MHz (-3dB).CPL8100 series provide two range option of 10A and 100A, the
users may choose the correct range according to the current value. The auto zero function
make it easy for the users to operate, and it also has power and low voltage indicator as well
as overload sound alert. The probe can be powered by battery or external power supply,
which makes the measurement a lot more convenient. With standard BNC output port, the
probe can connect to any oscilloscope, and it can also connect to multimeter with
BNC-banana plug. The CPL8100 series is usually used in power supply , motor drive and
power supply.

4. Operating instruction
 Set the coupling mode of the oscilloscope to DC and the input impedance to 1MΩ; To
make it easy to read, users can set the display unit of the oscilloscope from voltage to
current display. If user’s oscilloscope doesn’t have such function, user have to manually
set the corresponding attenuation ratio, for instance, if the probe is H level （0.01V/A）,
the oscilloscope should be 100X; if the probe is L level （0.1V/A）, oscilloscope is 10X.
User can connect the BNC output port with the input port of the oscilloscope with
standard double terminal BNC cable.
 Turn the switch to ON, and the power indicator will light up green.

 According to the value of the current under test, choose the correct range by pressing
button.
Attention: Different range correspond to different attenuation ratio of the oscilloscope.
 Press the Auto Zero button . The buzzer will beep for twice, or it will have a long and
continuous beep meaning the failure of Auto Zero .The external magnetic field can have a
little influence to the DC zero, so do not move the device after Auto Zero.
 Open the clamp of the probe and clamp the conductor under test.
Attention: There’s direction tip on the current probe clamp. If the direction of the current
fits the tip, output will be positive; On the contrary, the result is negative.
 Adjust the vertical sensitivity of the oscilloscope to get a stable waveform.
