Figure 3-10 Vertical Control Zone
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.
Vertical offset back to 0 shortcut key
Turn the Vertical Position rotary control to change the vertical display position of
channel and push the position rotary control 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 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.
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.
