Trigger Level Indicator
The trigger level indicator is a color-coded triangle
that is positioned vertically on the grid.
In Stop trigger mode, the solid triangle also appears
with a hollow triangle of the same color if the level
is changed at that time. The hollow triangle
indicates what the trigger level is for the next valid
trigger.
NOTE: The Trigger Level indicator is not shown if the
triggered channel is not displayed.
Change trigger level using the front panel knob in
the Trigger Control area. Rotate the knob to adjust,
or push to set to 50% of the signal level.
Trigger level is specified in volts and remains unchanged when you change
the vertical gain settings or offset.
The amplitude and range of the trigger level are limited as follows:

± 4.1 screen divisions with a channel as the trigger source

± 0.5 V with EXT as the trigger source

± 5 V with EXT/10 as the trigger source

None with LINE as the trigger source (zero crossing is used).
