4. Acqui Menu
The Acquisition mode is accessible only when there is an SD card
present (controllers with the Data Logging, or DLC function). It is used
to enable or disable the logging of system Events or transmitter
information. The information is logged (or recorded) on an SD card.
Intervals or conditions must be defined before using this option.
The first line of the Acquisition screen offers either:
Delay mode: Allows for delay intervals of 10 to 59 seconds
or 1 to 60 minutes.
Threshold mode: Allows log values to be set according to set
variation thresholds (based on last reading) of
3% or more, 5% or more or 10% or more of
last detected concentration.
If a 3% threshold is selected, the system will not log a value at 3% but
will log a value of 3.1%. Remember that the sampling rate (system
refresh rate) may have an impact on logging.
Here is an example of threshold logging. The logs a semi-colon
delineated text files.
