Turn the Vertical Position knob to change the vertical display position of channel
and push the position knob to set the vertical display position back to 0 as a shortcut
key, this is especially helpful when the trace position is far out of the screen and want
it to get back to the screen center immediately.
2. Change the Vertical Setting and Observe the Consequent State Information Change.
With the information displayed in the status bar at the bottom of the waveform
window, you can determine any changes in the channel vertical scale factor.
 Turn the Vertical Scale knob and change the "Vertical Scale Factor (Voltage
Division)", it can be found that the scale factor of the channel corresponding to
the status bar has been changed accordingly.
 Push buttons of CH1, CH2 and Math, the operation menu, symbols, waveforms
and scale factor status information of the corresponding channel will be displayed
in the screen.
Introduction to the Horizontal System
Shown as Figure 3-12, there are a button and two knobs in the Horizontal Controls. The
following practices will gradually direct you to be familiar with the setting of horizontal
time base.
Figure 3-12 Horizontal Control Zone
1. Turn the Horizontal Scale knob to change the horizontal time base setting and
observe the consequent status information change. Turn the Horizontal Scale knob to
change the horizontal time base, and it can be found that the Horizontal Time Base
display in the status bar changes accordingly.
2. Use the Horizontal Position knob to adjust the horizontal position of the signal in the
waveform window. The Horizontal Position knob is used to control the triggering
displacement of the signal or for other special applications. If it is applied to
triggering the displacement, it can be observed that the waveform moves horizontally
with the knob when you rotate the Horizontal Position knob.
