7.1.5.2. Editing iDAS Triggering Events 

Triggering events define when and how the iDAS records a measurement of any given data channel.  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.
