Revision History

Ver. 1.06 March 3, 2020

  • Revised battery warning criteria to avoid repeating “warning” and “recovery” state changes when the battery level is low.
  • After returning from Sleep Mode(*), auto-upload of previously recorded data is performed. After that, the logger automatically resumes recording and auto-upload of data.
    *Sleep Mode is a feature that stops recording when battery power is low and protects recorded data.
  • Fixed a problem that occurred when the auto-upload interval was set shorter than the recording interval, all recorded data could be sent instead of only new data since the last upload.
