To perform the Probe Compensation

When connect the probe with any input channel for the first time, make this
adjustment to match the probe with the input channel. The probe which is not
compensated or presents a compensation deviation will result in the measuring error
or mistake. For adjusting the probe compensation, please carry out the following
steps:
1. Set the attenuation coefficient of the probe in the menu as 10X and that of the
switch in the probe as 10X, and connect the oscilloscope probe with the CH1
channel. If a probe hook tip is used, ensure that it keeps in close touch with the
probe. Connect the probe tip with the signal connector of the probe compensator
and connect the reference wire clamp with the ground wire connector of the
probe connector, and then press the button AUTOSET (see Fig.5).
2. Check the displayed waveforms and regulate the probe till a correct
compensation is achieved (see Fig.7 and Fig.8).

3. Repeat the steps mentioned if necessary.
