The Listing Menu
Trig to X/Trig to 0 Fields
Statistics are based on the time between the X and 0. Both markers
must be found before valid statistical information is displayed.
In repetitive run mode, the display is updated each time a valid run
occurs until you select Stop. If you select Run after Stop, the
statistics continue to update without loss of information.
In single run mode, each time you select Run an additional valid run
will
be added to the data and the statistics will be updated. This
process continues unless you change the placement of the X and 0
Pattern markers between runs.
