File Structure
A data log file is a collection of readings recorded in a single day. They
are ordered in time, from top to bottom, and grouped into sessions. A
session begins when data logging is started, and ends when it is stopped. A
sensor information header always precedes the gas readings. Since the
header includes the “Range” of the sensor, changing this setting while
logging will create a new sensor information header.
