The Acquisition mode is only accessible 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% threshhold 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.
