  • Changed dither cavity pressure set point to improve control loop.

Version 2.1.37 (released September 24, 2021)

  • Improved vibration-induced noise performance.
  • Removed A, B, C Pump Adjustment setting; no longer needed due to the improved vibration-induced noise performance.

Version 2.1.35 (released August 18, 2021)

  • Changed graph decimal precision from five places to three places.
  • Changed the way graph tool tips are displayed to ensure correct placement at all screen sizes, including unconventional or uncommon dimensions.
  • Improved detection of user browser/mobile device settings to improve experience across platforms.
  • Fixed bug where History graph would show incorrect end times at certain zoom levels.
  • Fixed bug where certain screen resolutions would render graph tool-tips unreadable.
  • Fixed bug where Android phones could enter a Remark of more than 15 characters.
  • Fixed bug where failing to include end time on a data export would crash the download.
  • Fixed bug where above bug fix would crash download specifically on Safari (all blank end times are now automatically changed to 00:00 of the following day).
  • Fixed bug where History graphs would fail to resize in Safari.
  • Fixed various responsive styling issues in Safari.
  • Fixed bug where Low Flow Config modal was no longer visible on Settings page.
  • Fixed bug where header information (serial number, connection status, etc.) was no longer visible in Spanish language mode.
  • Fixed bug where SD card logging errors in header would not change to reflect selected language mode.
  • Improve second ring-down logic to improve stability when there is a skipped mode.
  • Added functionality to improve handling of fast gas concentration transients.
  • Fix default phase setpoint for TG20.
  • Remove feature to try to keep timestamp at 0 fractional seconds which would break the averager.
  • Remove alternation in zero cal and when initializing start frequency.
  • Expand TG20 self cal laser temperature range.
  • Updated interface so it is compatible with a new browser update.
  • Remove N2O spectra weight from TG10 and TG15 log file.

Version 2.1.16 (released May 14, 2021)

  • Support for comments to be recorded with measurements.
  • Support for automatic power on. When power is supplied through the main power connector, the instrument will power on automatically. Hardware upgrades are required to enable this option in older instruments.

  • Added warmup status, battery charge status, and Wi-Fi status to the header.
  • Added dedicated calibration section.

Other changes:

  • Reorganized sections of the interface.
  • Rearranged icon order.
  • Removed flow rate diagnostic.

Version 2.0.17 (released August 14, 2019)

Bugs fixed:

  • Fixed start-up timing issue that prevented measurements in rare instances.

Version 2.0.13

New features:

  • LI-8100A integration. You can connect the instrument to an LI-8100A and synchronize the clocks of both instruments.
