1.2.2.2 Logger Memory
The Memory subsection indicates how the data is stored in memory and what the start and
end times (or capacity) are for the data logging. In the FIFO (First In, First Out) mode, the
logger continually stores data and when the memory limit is reached, the new readings start to
overwrite the oldest readings. Using this method, the logger is always collecting data, but only
saves the most recent data in its memory. In the Stop When Full mode, when the memory
limit is reached, the logger stops recording.
The length of time for data capture of the logger is determined by the sampling rate. To find
out more about how the capacity is affected by the sample rate, see Appendix B Sample
Rates .
Usage
To set how the logger stores its data, click on the Usage field and select FIFO or Stop When
Full.
Start Time
To set when the logger will start recording click on the Start Time field. Next, click on the
small button that appears at the right. This will pop up a form allowing you to set the date and
