(4) Function Check
Press the AUTO key, a 3 Vpp 1 kHz square wave should appear. Repeat step 3 for all channels. If
the output is not a square wave with the above descriptions, please perform the probe
compensation step in the next section.
(5) Probe Compensation
When the probe is connected to any input channel for the first time, this step might be adjusted in
order to match the probe and the input channel. Probes that are not compensated may lead to
measurement errors or mistake. Please follow the following steps:
① Set the attenuation coefficient in the probe menu and the switch on the probe to 10x, and connect
the probe to CH1. Make sure the probe’s connector is properly connected with the oscilloscope.
Connect the probe’s main clip and ground clip to the oscilloscope’s compensating signal and
ground terminal respectively. Open CH1 and press the AUTO button.
② View displayed waveforms, as shown in Figure 4-2.
Excessive Compensation Correct Compensation Insufficient Compensation

③ If the displayed waveform is look like the above “Insufficient Compensation” or “Excessive
Compensation”, use a non-metallic screwdriver to adjust the probe’s variable capacitance until the
display matches the "Correct compensation" waveform.
Warning: To avoid electric shock when using the probe to measure high voltage, please ensure
that the probe insulation is in good condition and avoid physical contact with any metallic part of
the probe.
