1. 1, 1, open the oscilloscope, as shown in the figure, find the MENU, click to enter, find the voltage multiplier, as shown in the figure for the x10 gear (gear can be selected by yourself, and the probe can be consistent).
2, if you use the probe hook front end attachment, please connect the signal pin front end firmly on the probe to ensure the correct connection.
3. Check the shape of the displayed waveform. It may appear as follows, in which over and under both need to adjust the probe to be able to better test the accurate value.
4. If the waveform is not correct, please adjust the probe. As shown below, until the waveform for the above compensation for the correct waveform, that is, the oscilloscope calibration is successful.
