Fig. 4-9 Vertical Control Zone
1. Use the button "VERTICAL POSITION" knob to show the signal in the center
of the waveform window. The "VERTICAL POSITION" knob functions the
regulating of the vertical display position of the signal. Thus, when the
"VERTICAL POSITION" knob is rotated, the pointer of the earth datum point
of the channel is directed to move up and down following the wave form.
Measuring Skill
If the channel is under the DC coupling mode, you can rapidly measure the DC
component of the signal through the observation of the difference between the wave
form and the signal ground.
If the channel is under the AC mode, the DC component will be removed by filtration.
This mode helps you display the AC component of the signal with a higher
sensitivity.
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.
 Rotate the vertical "VOLTS/DIV" 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.
 Press buttons of "CH1 MENU", "CH2 MENU" and "MATH MENU", the
operation menu, symbols, wave forms and scale factor status information of the
corresponding channel will be displayed in the screen.
