Revision History

Ver. 1.05October 16, 2023

  • Some operations of the battery level warning have been revised.
    - Revised battery warning recovery criteria to avoid sending low battery warnings repeatedly.
    - Changed the state of battery warning sent when a low battery recovery has occurred from 1 (normal) to 81 (recovery to normal).
    - Changed the specifications for sending any untransmitted battery warnings when low battery recovery has occurred.
  • Added functionality to send the state of Warning Lifted (state:82) when the warning settings have been changed, the recording has been started, or the device has been reset while in a warning state.
  • Functionality was added whereby if upon recovery from a sensor error, an upper/lower limit warning is still active, the status (state:83) will be sent.
  • When sending data via a proxy server, the connection is now made using a host name instead of an IP address. (White list compatible)
  • Previously command processing was aborted when the response from an HTTP server was R=0 (command rejected). Processing has now been modified so that a request is issued for the command specified by the flag contained in the response.
  • Fixed a problem that occurred when the auto-upload interval was set to 24 hours, where recorded data was being sent every 5 hours and 50 minutes.
  • The measured values displayed in warning e-mails have been changed from the “instantaneous values” at the time of warning judgment to the “max/min values” during the specified judgment time.
  • Sensor error information was added to Bluetooth advertisement packets.
  • Fixed an issue that occurred when resending multiple warning data after transmission failures (due to low battery, etc.), where the battery status at the time of successful transmission was reported instead of the battery status at the time of the warning.

Ver. 1.04August 7, 2023

  • Fixed a problem in which the temperature measurement range before reporting an error was narrower than the specification.
    Thermocouple Type: Before/After Correction
    Type K: -199 to 1270 °C / -199 to 1370 °C
    Type J: -199 to 1100 °C / -199 to 1200 °C
    Type T: -199 to 300 °C / -199 to 400 °C
    Type E: -199 to 900 °C / -199 to 1000 °C
    Type S: -50 to 1660 °C / -50 to 1760 °C
    Type R: -50 to 1660 °C / -50 to 1760 °C

Ver. 1.03August 30, 2022

  • Fixed a problem where the time of the first data could be recorded incorrectly in the following situation: You start the recording after changing the recording interval with the buttons on the logger, and keep pressing the REC/STOP button after the REC icon appears on the LCD.

Ver. 1.02June 27, 2022

  • Fixed a problem that occurred when setting the device clock to "Synchronize with SNTP Server", where the synchronization failed in rare cases and caused incorrect timestamp calculations.
    See here for details.

Ver. 1.01 March 14, 2022

  • Changed the message to be displayed on the LCD when the battery voltage is low from [dEAd bAtt] to [Lo bAtt].
  • When passcode lock is enabled and you enter the wrong passcode three times in a row, the lock cannot be disabled for one minute now.
