be generated.
2. If the datalogger is being used for the rst time, a new le LXA01001.
XLS will be generated under the route LXA01\. After exiting the
datalogger and executing the function again, the data is saved to the
LXA01001.XLS le until the data reach 30,000 data columns. A new
le will then be generated (i.e., LXA01002.XLS).
3. The folder LXA01\ will hold 99 les. A new route (i.e., LXA02\) will be
generated when exceeding 99 les.
