To set the Probe Attenuation Coefficient

The probe has several attenuation coefficients, which will influence the vertical scale
factor of the oscilloscope.
If it is required to change (check) the set value of the probe attenuation coefficient,
press the function menu button of the channels used, then push down the selection
button corresponding to the probe till the correct set value is shown.
This setting will be valid all the time before it is changed again.
Note: The attenuation coefficient of the probe in the menu is preset to 10X when
the oscilloscope is delivered from the factory.
Make sure that the set value of the attenuation switch in the probe is the same as the
menu selection of the probe in the oscilloscope.
The set values of the probe switch are 1X and 10X (see Fig.9).
Note: When the attenuation switch is set to 1X, the probe will limit the bandwidth
of the oscilloscope in 5MHz. If it is needed to use the whole bandwidth of the
oscilloscope, the switch must be set to 10X.
