1.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:
(1) Click to show the Function menu, choose "Channel".
(2) Click to select the channel that the probe connects with (CH1 or CH2).
(3) Set "Probe Rate" to 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 in the software is preset to X10.
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 software.
The set values of the probe switch are X1 and X10.
Caution:
When the attenuation switch is set to X1, the probe will limit the bandwidth of the
oscilloscope in 5 MHz. To use the full bandwidth of the oscilloscope, the switch
must be set to X10.

2.How to Set the Vertical System

You can set the corresponding parameters of vertical system in the Channel window (18/19 in
In the voltage division list, you can select the proper value. Take VDS3102(L) for instance.
You can set the zero point position through the control bar to regulate of the vertical display position of the signal. You can also drag the zero
point position pointer (22, 23 in
