1. Use the "VERTICAL POSITION" rotary control to show the signal in the
center of the waveform window. The "VERTICAL POSITION" rotary control
functions the regulating of the vertical display position of the signal. Thus, when
the "VERTICAL POSITION" rotary control is rotated, the pointer of the earth
datum point of the channel is directed to move up and down following the
waveform.
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 would be filtered out.
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.

Turn the vertical "VOLTS/DIV" rotary control 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", the operation
menu, symbols, waveforms and scale factor status information of the
corresponding channel will be displayed in the screen.
