Adjusting the Vertical Setup
TLS 216 User Manual

NOTE . Vertical positioning is a display function. Changing position simply
moves the ground reference level of a group above or below the zero position
level (center screen). You also can adjust the group position by adjusting the
offset using the Vertical Controls menu (discussed later in this article). See
NOTE on page 3–10.
To Check Vertical Settings
To quickly determine the vertical scale for the selected group, check the Vertical
Readout at the bottom of the display. It lists each group by number and lists the
last and first channel of each group.
If the group display mode is Analog, the readout also shows the group volts/
division setting. If the group display mode is Off, BusForm, or Timing Diagram,
OFF, Bus, or Timing replaces its volts/division readout. (See Figure 3-4.)
NOTE
. The Vertical Readout varies its display based on the logic scope setup.
See To Check Group Settings on page 3–56 for a complete description of the
Vertical Readout.
