1. Summary
CPL5100 is a kind of current probe that can measure both DC and AC current up to
100A (70.7Arms). The band width of CPL5100 is 600 kHz (-3dB).CPL5100 provides 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 CPL5100 is usually used in power
supply , motor drive and power supply.
2. Introduction about probes and accessories
 Probe
 Power Switch:

ON: Power on and probe work; OFF:Power off and probe do not work.
 Power indicator: When the power switch is on, the indicator is lighted green.
 Battery Low Voltage Indicator: when the voltage of the battery is lower than 6.5V, the
power indicator will light red, reminding the users to change battery.
 Range Switch: press the button switch to change between H and L Range.
 Range Indicator: indicating the current Range choice. H level: 100A; L level: 10A.
 Auto Zero button: to make accurate measurement, users need to do zero degaussing
before measuring to avoid the influence of environment factors like earth magnetic field
and temperature shift.
 Auto Zero Indicator: when Auto Zero, the indicator is lighted on and in green and will
be turned off when the Auto Zero is finished.
 Clamp: the clamp used for current measurement; the max diameter for the cable is
12mm.
 External Power Supply Plug: powered by external DC supply.
 Battery Box: standard 9V alkaline battery is used. Please turn off the switch and
disconnect from the conductor under test & oscilloscope when changing battery.

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 ranges 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.
