Bugs Fixed
- Set limit for pre-purge to 5 seconds and post-purge for 0 seconds.
- Resolved issued with manifold valve state when loading configuration page in the interface.
- Improved reporting of chamber status.
- Added 15 second delay after a measurement is aborted due to a flow restriction.
- Improved system performance following multiplexer reboot scenarios.
- Truncated significant digits after a decimal to 2 characters in the interface.
- Improved communication between the LI-870 and multiplexer (changes to the LI-870 firmware).
- Improved detection and display of trace gas analyzer nodes.
- Improved performance of connection when a computer is reconnected to the device network after being connected to a different network.
- Improved alignment of Stevens Probe SDI-12 measurements with other chamber measurements to avoid missing soil water content and temperature data.
- Additional refinements.
Version 2.0.0 (released December 3, 2021)
- Added support for extension manifolds.
Version 1.2.5 (released March 17, 2021)
Embedded firmware
- Now continues to track chamber status beyond end of measurement
Interface changes
- Shows correct number of files found
- Fix chambers expanded state in diagnostics page
- Fix some color inconsistencies
- Refactor tool-tips
- Add files error dialog to deletion and copy on USB operations
Chamber changes
- More gracefully handle a close limit or open limit sensor failure
- Cache measurement set configuration info while SDI-12 device is performing measurement
- Report -9999 for SDI-12 fields that are not reported by device due to a misconfiguration
- Does a full SDI-12 measurement reinitialization on start command even if already in measurement mode
