Once the pressure rises above the clutch level, the RE Qualifier
assumes that the clutch has turned the tool off.
The vertical lines on top of the graph represent timers. The line
labeled Ts represents the point at which minimum run timer and
the maximum run timer start. This line will always be located at
the point which the pressure signature crosses the run start level.
T- indicates the point at which the minimum run timer was satis-
fied. T+ indicates the point at which the maximum run timer
would be violated. CL1 and CL2 are the beginning and end of
the clutch timer. The clutch timer will always begin at the point
where the pneumatic signature crosses the clutch level.
Using the ZOOM IN and ZOOM OUT soft-keys, the user can
compress and expand the graph along the time scale. This feature
may be useful in seeing items that may have occurred after the
pneumatic level dropped back below the cycle start level. The
maximum run timer is often off screen for the initial plotting of
the pneumatic curve.
Pressing the RETURN soft-key will return the software to the
main screen without locking the unit. Pressing the LOCK AND
RETURN will lock the unit and return the software to the main
screen.
