Figure 4-10 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 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 knob to change the vertical display position of
channel and press 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 "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
～
CH4 and Math, the operation menu, symbols,
waveforms and scale factor status information of the corresponding channel will
be displayed in the screen.
You can also set the vertical system through touchscreen, see "Set the Vertical System
