Chapter 2 Vertical System Setting

To Turn Waveform Invert On/Off

Press CH1 and its backlight is illuminated; then, press Invert to turn on or off
waveform invert (the default is off). When waveform invert is turned off, the
waveform display is normal; when waveform invert is turned on, the waveform
voltage values are inverted (as shown in the figures below).
Note: Turning waveform invert on will change the results of math operations and
waveform measurements.

To Specify the Vertical Reference

The vertical reference refers to the reference position according to which the
waveform of the corresponding channel is expanded or compressed vertically when
using VERTICAL
Press Utility  System and press VerticalExp to switch the current vertical
reference (the default is Ground).

SCALE to modify the vertical scale of the analog channel.
Center: when the vertical scale is modified, the waveform of the corresponding
channel will be expanded or compressed relative to the center of the screen.
Ground: when the vertical scale is modified, the waveform of the corresponding
channel will be expanded or compressed relative to the ground level.
