4.4.5 Set Probe Attenuation Coefficient
When measuring with a probe, the correct measurement result can only be obtained by setting the correct probe
attenuation ratio. In order to match the actual probe attenuation ratio, it is necessary to adjust the channel
attenuation factor correspondingly under the channel menu. When probe attenuation ratio is changed, the
corresponding attenuation ratio must be set on the channel menu to ensure the correctness of the waveform
amplitude and measurement result displayed by the oscilloscope.
Probe attenuation ratio and menu attenuation ratio are shown in the table below:
