5. 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:
1. Set the attenuation coefficient of the probe in the menu as 10X and that of the switch in the probe as 10X
(see “4.10. How to Set the Probe Attenuation Coefficient” on P 14), 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”.
2. Check the displayed waveforms and regulate the probe till a correct compensation is achieved (see Fig. 7
and Fig. 8).
