9.4. To adjust the probe attenuation
For correct measurements, the attenuation coefficient settings in the operating menu of the Channel
should always match what is on the probe (see 8.1. How to Set the Probe Attenuation Coefficient). If
the attenuation coefficient of the probe is 1:1, the menu setting of the input channel should be set to
X1.
Some operations could be done in Channel window:
