The group reference indicator shows the vertical position of any channels that
Group 1 contains when the channels have no input signal. For the current group
display mode (Analog), this indicator points to the ground level for all channels
in the group when vertical offset is set to 0 V in the group menu; when vertical
offset is not set to 0 V, it points to the vertical offset level.
The trigger readout shows that the logic scope triggers using the edge of a signal
(rising or falling signal transitions that pass through the trigger threshold).
The time base readout shows that the main time base is set to a horizontal scale
of 500
m
s/div.
The vertical readout indicates that Group 1 is displayed and that it includes
Channel 1 as the first and also the last channel in the group. The logic scope uses
this format for each group readout in the vertical readout: group number [last
channel:first channel] group volts/division setting.

Right now, the channel, time base, and trigger readouts appear in the graticule
area to make room for display of the menu. You can press the CLEAR MENU
button any time to remove any menus and to move the readouts below the
graticule.
