7.1.5. EDITING DAS TRIGGERING EVENTS

06864B DCN6314
Triggering events define when and how the DAS records a measurement of any given
data channel. Triggering events are firmware-specific and are listed in Appendix A-5.
The most commonly used triggering events are:
•
ATIMER: Sampling at regular intervals specified by an automatic timer. Most
trending information is usually stored at such regular intervals, which can be
instantaneous or averaged.
•
EXITZR, EXITSP, and SLPCHG (exit zero, exit span, slope change): Sampling at
the end of (irregularly occurring) calibrations or when the response slope changes.
These triggering events create instantaneous data points, e.g., for the new slope
and offset (concentration response) values at the end of a calibration. Zero and
slope values are valuable to monitor response drift and to document when the
instrument was calibrated.
•
WARNINGS: Some data may be useful when stored if one of several warning
messages appears such as WTEMPW (GFC Wheel temperature warning). This is
helpful for troubleshooting by monitoring when a particular warning occurrs.
To edit the list of data parameters associated with a specific data channel, follow the
instruction shown in Section 7.1.4 then press:
