/DIV control will expand or compress the waveform. In dual-window mode, push button F1 to
select major or minor window. When the major window is selected, the F1 button provides the
same functions as it provides in single-mode window. When the minor window is selected, press
TIME/DIV button to scale the waveform whose magnification is up to 1000.
5.2.1 Scan Mode Display (Roll Mode)
With the TIME/DIV control set to 80ms/div or slower and the trigger mode set to Auto, the
oscilloscope works in the scan acquisition mode. In this mode, the waveform display is updated
from left to right without any trigger or horizontal position control.
5.3 Vertical Controls
Vertical controls can be used to display and remove waveforms, adjust vertical scale and position,
set input parameters and perform math calculations. Each channel has a separate vertical menu
to set. See below for menu description.
1. VERTICAL POSITION Bar: Move the channel waveform up and down on the screen. In
dual-window mode, move the waveforms in both windows at the same time in a same direction.
Two channels correspond to two bars.
2. Menu (CH1, CH2): Display vertical menu options; turn on or off the display of channel
waveforms.
