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 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.
