QML data logger stores the measured and calculated data in the internal memory. The internal memory is a Flash chip with a data storage capacity of 3.3 MB. The internal memory is used as a temporary non-volatile storage for reports that are scheduled to be transmitted to an external server.

QML data logger generates a daily log file and saves it on the external CompactFlash memory card in the QML data logger, in the /Ext/<station name> subfolder, at midnight. The default time is 00:05:00. The logger deletes the log files automatically after 366 days.

Always use an external memory card in the logger, or the internal log memory may fill up.

The daily log file is a binary DAT file that can be converted to CSV with AWS Client. The filename is L0YYMMDD.dat.

  • L0 = Log group name for daily log files
  • YY = Year in 2 digits
  • MM = Month in 2 digits
  • DD = Day in 2 digits
The QML data logger uses UTC time in data logging and managing log files.
