OPERATION
The first display is:
1. Indication of maximum (furthest from zero)
pressure included in the sequence which is about
to run.
This screen is offered as a means for the user to check, prior to execution, that
the correct sequence is selected and that it does not exceed the range of the
device or system being tested. Pressing [ESCAPE] returns to the main run
screen without sequence execution. Pressing [ENTER] causes sequence
execution to proceed.
Pressure control will begin to set the first target value of the sequence (or vent will
execute if the first increment is zero gauge pressure or a vent command).
The display is the Main Run Screen (see Section 3.1.1) with indication of the
sequence progress:
1. Indication of sequence increment that is currently
being controlled/total increments in sequence.
Changes to ENTER or countdown time remaining
once Ready (<*>) condition has been reached at
target value.
Except for the bottom right hand corner, the sequence run display is identical to
the normal main run screen (see Section 3.1.1). The bottom right corner provides
information on sequence execution. This information updates as each sequence
increment is executed.
If the sequence was set up with <Next increment on timed delay>, execution
will proceed automatically from increment to increment after a Ready <*>
condition has occurred at the increment and the countdown timer has expired.
If the sequence was set up with <Next increment on ENTER>. Press [ENTER]
to continue to the next increment.
