Revision History

Ver. 1.07 April 24, 2023

  • Minor bug fix.

Ver. 1.06 March 29, 2022

  • Added a function to output the recording status of the device on the T&D WebStorage Service.
  • When the recording mode is set to One Time, the REC mark on the LCD now disappears automatically when the logger reaches full capacity.
    *It is no longer necessary to use the REC/STOP button to turn off the REC mark manually when FULL appears on the logger.
    Please note that pressing the REC/STOP button once the REC mark has disappeared will result in deletion of the recorded data and will start a new recording session.

Ver. 1.05 December 15, 2021

  • Fixed a problem that occurred when configuring wireless network settings (for auto-upload of recorded data) using WPS, where the proxy server configuration was overwritten by another network’s pre-existing configuration.

Ver. 1.04 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.

Ver. 1.03 March 15, 2019

  • Fixed a problem where Bluetooth communication was not possible after testing the network connection in a state where battery level was too low to perform WLAN communication.

Ver. 1.02 March 01, 2019

  • Fixed a problem where communication via proxy server failed.
  • Fixed a problem that caused the wireless LAN connection test to fail.
  • Fixed a problem where time of the data downloaded via USB was incorrect.
