How to Implement 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:
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 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".
Check the displayed waveforms and regulate the probe till a correct
compensation is achieved (see Figure 8 and Figure 9).
