F.3 SD Card Status Menu Item
Whenever the concentration detected exceeds the preset alarm level in the CL1/CL2, the system starts a log
file on the SD card (if available).
The log file will update approximately every 2 seconds until the gas is no longer detected. A sample alarm file
is shown in figure F.2
The columns show: Date, Time, Gas Concentration, Alarm Level 1, Alarm Level 2, and the selected gas range.
