Function Check and Basic Operation
Function Check and Basic Operation
CAUTION: Do not force wires larger than 5.0 mm in diameter into the probe jaws,
as this may damage the probe. The mating surface of the probe head transformer
is precisely polished and should be handled with care. Dirt on the mating surface
of the probe head transformer may reduce measurement accuracy.
Use the following steps to check if the probe is working properly:
Connect the probe to any channel of the oscilloscope.
Set the oscilloscope
impedance to 1MΩ.
If the auto-zero calibration fails, press the degauss/auto-zero button to
perform manual zero calibration.
Secure the probe to the circuit.
Adjust the oscilloscope-related settings or use the oscilloscope's auto-setup
function to display a stable waveform. After seeing a stable waveform, it means
that the probe is working normally.

Here are some basic operations you should be aware
of:
Before connecting the oscilloscope, please slide the probe slider to the LOCK
position to lock the probe, otherwise it will affect the zero calibration accuracy.
Before connecting the probe to the lead, please check the oscilloscope, if there is
a DC offset, please degauss and zero the probe. (See page 4, Degaussing and Zero
the Probe)
Please do not touch the conductor under test and the sensor head of the
probe during measurement.
Close and lock the probe grip on the wire. For correct polarity readings, connect
the probe from positive to negative so that the direction of current flow matches
the arrow on the probe clip.
