How 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 Figure 7).
Figure 8.
Attenuation Switch.
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.

How to Use the Probe Safely
The safety guard ring around the probe body protects your finger against the
electric shock, shown as Figure 8.
