pointer indicating the Grounding Reference Point of the channel
moves up and down following the waveform. When press the Vertical
Displacement button, the vertical displacement can be zero.
Measuring Skills
If the DC coupling mode is adopted for the channel, observe the gap
between the waveform and the signal ground to quickly measure the DC
component of the signal.
If the AC coupling mode is adopted for the channel, the DC component of
the signal is filtered out, facilitating you to display the AC component of the
signal with higher sensitivity.
2. Change the vertical settings and observe the resulting status change.
You can determine the change of the vertical gear factor of any channel
through the information displayed in the status bar at the lower part of the
waveform window.
 Turn the Vertical Gear knob to change the Vertical Gear Factor
(Voltage Gear), and the gear factor of corresponding channel in the
status bar changes accordingly.
3. Press the CH1 and CH2 key to enable or disenable corresponding
channel.

A general Knowledge of Horizontal System

As shown in Figure 5-2, there is a key and two knobs in the Horizontal
Contral Area. The following exercises are to guide you through the use of
the horizontal time base settings.
1. Turn the Horizontal Gear knob to change the settings of the horizontal
time base and thus observe the resulting change of the status
information, then the corresponding Horizontal Time Base in the
status bar changes accordingly.
Press the Horizontal Gear knob enter or exit waveform amplification
mode.
2. Turn the Horizontal Displacement knob to adjust the horizontal
displacement of the signal in the waveform window.
3. The Horizontal Displacement knob is to control the triggered
horizontal displacement of the signal; when turning the knob, the
waveform moves horizontally with the knob.When press the
Horizontal Displacement button, the horizontal displacement can be
zero.
4. Press the HOR key to pop up the horizontal Settings window.
5.Use the Oscilloscope
