How to Set the Probe Attenuation Coefficient

The probe has several attenuation coefficients, which will influence the vertical
scale factor of the oscilloscope.
To change or check the probe attenuation coefficient in the menu of oscilloscope:
Press the function menu button of the used channels (CH1 MENU or
CH2 MENU).
Press H3 button to display the Probe menu; select the proper value
corresponding to the probe.
This setting will be valid all the time before it is changed again.
CAUTION: The default attenuation coefficient of the probe on the instrument is
preset to 10X. Make sure that the set value of the attenuation switch
in the probe is the same as the menu selection of the probe
attenuation coefficient in the oscilloscope.
The set values of the probe switch are 1X and 10X (see Figure 9).
CAUTION:
When the attenuation switch is set to 1X, the probe will limit the
bandwidth of the oscilloscope in 5MHz. To use the full bandwidth of
the oscilloscope, the switch must be set to 10X.
