11.3. Regulate the probe attenuation.
In order to match the attenuation coefficient of the probe, it is required to adjust the attenuation ration
coefficient of the probe through the operating menu of the Channel accordingly (see “6. How to set the Probe
Attenation Coefficient” on page 100). If the attenuation coefficient of the probe is 1:1, that of the oscilloscope
input channel should also be set to X1 to avoid any errors presented in the displayed scale factor information
and the measured data.
Take the Channel 1 as an example, the attenuation coefficient of the probe is 10:1, the operation steps is
shown as follows:
* Press the CH1 MENU button, access CH1 SETUP menu.
* Press the H3 menu selection, the Probe menu will display at the right of the screen, then press the F2
button to select X10 for the probe.
The Fig. 16 illustrates the setting and the vertical scale factor when the probe of the attenuation coefficient of
10:1.is used.
