CP6000/CP4000
Current Probe Instructions 17
Measurement methods:

Confirm the previous steps

Pull the switch control pole of the sensor, open the head of the sensor and
make the current direction mark in

Push the switch control pole of the sensor until the UNLOCK mark disappear.
Lock the probe, make sure the entire part is closed, and then observe the
waveform under test. Utilize the current transfer ratio to transform the voltage
sensibility into current sensibility. For instance, the ratio of CP6030 is 0.1V/A
(30A range), and then, when the voltage sensibility of the waveform monitor is
10mV/div, the current sensibility is 100mA/div
The method to deal with abnormal situation
Situation Possible reason Dealing method
Can’t measure DC, or
the value obtained is
comparatively low in
the frequency range
Power is off Turn on power
Oscilloscope set to AC coupling Set to DC coupling
Sensor is not locked Please lock the sensor
Auto degaussing or
zero setting
unsuccessful
The probe is on the operating
circuit under test when
degaussing or zero setting is
applied
Turn off the circuit
under test and zero set
again.
The amplitude is
comparatively
