7.1.4.2. EDITING DAS TRIGGERING EVENTS
Triggering events define when and how the DAS 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.
EXCO2Z, EXCO2S, EXCO2M, CO2SLC (exit CO

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.
