DATALOGGER
SD Card Data Structure
1. The rst time a SD card is used in this meter, a folder
AMA01 will be generated.
2. If the datalogger is being used for the rst time, a new
le AMA01001.XLS will be generated under the route
AMA01\. After exiting the datalogger and executing the
function again, the data is saved to the AMA01001.XLS
le until the data reach 30,000 data columns. A new le
will then be generated (i.e., AMA01002.XLS).
3. The folder AMA01\ will hold 99 les. A new route (i.e.,
AMA02\) will be generated when exceeding 99 les.
