Application of VERTICAL POSITION and VOLTS/DIV
Knobs
1. The .VERTIVAL POSITION knob is used to adjust the vertical positions of the
wave forms of all Channels (including those resulted from the mathematical
operation).
The analytic resolution of this control knob changes with the vertical division.
2. The VOLTS/DIV knob is used to regulate the vertical resolution of the wave
forms of all channels (including those obtained from the mathematical
manipulation), which can determine the sensitivity of the vertical division with
the sequence of 1-2-5. The vertical sensitivity goes up when the knob is rotated
clockwise and goes down when the knob is rotated anticlockwise.
3. When the vertical position of the channel wave form is adjusted, the screen shows
the information concerning the vertical position at the lower left corner (see
Fig.5-13).

How to Set the Horizontal system
The HORIZONTAL CONTROLS includes the HORIZONTAL MENU button and
such knobs as HORIZONTAL POSITION and SEC/DIV.
1. HORIZONTAL POSITION knob: this knob is used to adjust the horizontal
positions of all channels (include those obtained from the mathematical
manipulation), the analytic resolution of which changes with the time base.
2. SEC/DIV knob: it is used to set the horizontal scale factor for setting the main
time base or the window.
3. HORIZONTAL MENU button: Press this button to active TIME MODE shown
as below with description of each function (see Fig. 5-14).
