Acquisition Menu
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.
You must define intervals, or conditions 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 you to set log values 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 you select a 3% threshhold, 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.
