Using the eosAnalyze with LGR UGGA and eosMX

Tom Bishop

Configuration of the UGGA

The UGGA is relaively simple to configure – simply turning the instrument on will begin measurement and recording. The status of the instrument can be checked using a laptop or tablet computer. Download a copy of a VNC terminal program, connect to the WiFi network broadcast by the instrument (SSID and password printed inside the instrument), and connect using the IP address, username and password in the manual. This will give access to the diagnostic screens.

At this point I recommend making a record of any offset between the UGGA clock and local time.

Configuration of the eosMX

Click on the top menu bar to minimise the LGR UGGA monitoring software, and open the Eosense multiplexer control software. Use the dialogue to test the chambers mechanical operation and program the required cycle, and start the process. The cycle events and data from any connected sensors will be recorded.

Importing Data into eosAnalyze

  1. Place the UGGA recording file (gga_YYYY-MM-DD_fnnnn.txt) and the eosMX logfile (FRMonitor_nnnn.log) in the same folder as the software (eosAnalyze-AC_v3.6.2.exe).
  2. Open the software and in the menu Data > Analyzer Data Path set the location to the location of the software (eosAnalyze-AC_v3.6.2.exe).
  3. Toggle the Options > Toggle European Timestamp options so it is set to American timestamp format.
  4. Ensure that the LGR UGGA is selected in Options > Equipment > Select Analyzer Type.
  5. Ensure that Eosense eosAC (Multiplexed) is selected in Options > Equipment > Select Chamber Type.
  6. The default values in Options > Equipment > Chamber/Analyzer Settings are usually acceptable, but if you have modified the system, you may need to change them.
  7. If you have connected the auxiliary sensors, you must configure them in Options > Equipment > Configure Auxiliary Sensors. We have Decagon MAS-1 and RT-1 instruments available.
  8. Now click on Collect Data and set the time range for your required measurements. I recommend setting a time range larger than the experiment duration so no data is truncated.
  9. If the process has been successful, you will see measurement records appear in the Measurements window. Double click on one of the measurement records to bring up the Measurement Settings dialogue.
  10. Modify the lower and upper deadbands (shown on the graph in green and red respectively) by changing the Data Domain values. Try to exclude the obviously bad data at the beginning and end of the measurement duration. Select Apply Deadband Range To All and OK to apply these parameters to all of the measurements.
  11. To export the processed data, select Data > Export Data Table and select a location for the data file.
