Version History

Version Changes
2.0.3.0
  • Changed the 'Experiment Name' field to 'Sample Name'.
  • Updated how data is saved in the backend, as well as the naming convention used.
    • Files are now saved in the chosen directory instead of a new folder.
    • File names now start with the chosen sample name.
    • File names no longer include the date and time.
    • If a file with the chosen name already exists in the specified directory a number will be added to the end of the file name.
  • Fixed a bug that limited the long edge field to 140 mm, and the short edge field to 70 mm.
    • Both fields (and diameter) now have a maximum of 600 mm.
2.0.2.2
  • Fixed a bug that prevented negative voltages from being used in the maximum voltage field.
  • Moved the directory selection button to the directory field.
2.0.2.1
  • Updated the colour scheme of the UI to lighter theme.
2.0.2.0
  • The save directory is now included in settings profiles.
2.0.1.4
  • Fixed a bug that prevented the user creating settings profiles.
2.0.1.3
  • Fixed a bug that caused the program to crash when measuring sheet resistances of 0 Ω/square.
2.0.1.2
  • Warnings now clear after 10 seconds.
  • The measurement now cancels if:
    • The current limit is reached for the select range.
    • There are less than 3 data points in the initial IV measurement.
2.0.1.0
  • Major update to the user interface to improve consistency with other software.
  • Settings profile options are now with the "Measure" and "Cancel" buttons.
  • "Range" and "Samples per Point" options are now with the system connection options.

    • Range 4: increased from 100 μA to 200 μA.
    • Range 5: increased from 10 μA to 20 μA.
  • An option to set probe spacing has been added to allow different probe heads to be used.
  • Added the ability to perform measurements with negative target currents.
  • Increased the maximum sample thickness from 5000 μm to 10000 μm.
1.1.2.0
