JETI LiVal Changelog

Version history of JETI LiVal (Last updated on November 12, 2021)


- Widged NDVI added
- EML (Equivalent Melanopic Lux) added to Circadian widget
- Show measurements selection extended by display option of selected spectra (not only active or all as before) - concerns Spectrum, Chromaticity xy and uv, Spectral calculations and L*a*b* (plane). The selection is now always applied to all these widgets.
- Row names of the table view can be displayed and hidden as table labels

- Export of the table added again as a menu item
- Changed "Xmel" to "Xe,mel" for Circadian
- When screenshotting graphs, only the graph is saved, not the entire graph panel.
- The selection of saving the measurement information for He/Hv, Hazard and Museum values when saving the reference is now only possible if corresponding measurement values also exists.
- After loading a reference file, the last loaded spectrum is marked as active and selected.

- In the PAR widget, selecting the Ephot values via wavelength ranges did not work for the current measurement -> fixed
- Line shift in table according to Circadian with measuring mode != Irradiance -> fixed
- Removed yellow marking for stray light correction for "Load reference"
- If the original settings for museum and/or hazard measurements were not saved, these values are no longer calculated after file import. Previously, these values were sometimes displayed with incorrect measurement settings after import.
- Auto-zoom in xy- and uv- diagram only worked when showing the active spectrum -> fixed
- Selection of measurements is now retained even after pressing the Normed button in the spectrum view
- Added check to system directory (e.g. "C:\" or "C:\Program Files") when saving files, as files are otherwise moved to the VirtualStore by the UAC virtualisation if LiVal was started without administrator rights.


- Support for devices with stray light correction
- Blue Measurement - Widget
- Optional screen darkening during the measuring process
- Hazard measurements:
  * Alternative method of hazard measurement for blue light, retina thermal and retina thermal weak in irradiance measurement mode
  * User guidance for blue light measurement according to IEC 62471
- Calculation of Luminous Exposure (Hv) and Radiant Exposure (He):
   * If using table view: only available for continuous measurement in Irradiance measurement mode
   * If using history view: available in irradiance measurement mode over all current measurements

- Table:
   * Table window redesigned
   * When changing the measurement mode or calibration file, the entries shown in the table are no longer always deleted and can still be exported. The actually measured values are deleted as before.
  * The table can now be copied to clipboard including row labels.
- Hazard measurement redesigned:
  * The calculation is now only available in Radiance and Irradiance measurement mode.
  * Settings for future measurements (left widget side) and the display of the measurement results (right side) are now independent
  * In Radiance mode, the set Fov must necessarily correspond to the Fov of the calibration file, otherwise measurement will not be carried out
  * The calculation and displayed values are based on the calibrated wavelength range of the selected measurement, no longer on the wavelength range of the currently connected device and also independent of the selected Calculation Range.
- Measurement mode Radiant Intensity:
  * Distance query removed from the menu items "Options/Photometric units/SI Units" and "Options/Photometric units/Imperial units"
  * When loading the saved measurements from SPC, CSV and Temp files, the distance is now read from the file.

- Hazard: settings in the widget have influence only on subsequent measurements (not on previous; nothing is recalculated if settings are changed)
- Hazard: Now, Hazard is not calculated if some Spectral Weighting Function is loaded (to avoid confusion with double-applied weighting functions). If that's a case, a notice about it is shown in the Hazard-widget.
- Hazard: Options->Table - if Hazard is checked, Calibration File is also checked and dimmed to make it impossible to unckeck it.

- Hazard: Maximum time in Retina Thermal Weak mode had no upper limit. -> fixed (now it is 28800 seconds = 8 hours, after what it gets the value of PositiveInfinity)
- PromptPopup (dialog to enter a string) had false behaviour: if input something and clicked with a mouse somewhere in the dialog, always the same event as after clicking on the "OK"-button has been fired. -> fixed
- Export of multiple measurements in .CSV could take long because of a bug in .CSV-exporting routine. -> fixed

- In case of fixed-tint-measurements value of "adapted averages" was 0, what led to improper values in the table. -> fixed
- Labelling of ranks was not nice on xy-chart. -> fixed


- Two widgets for L*u*v* color space: L*u*v* and sC*h.

- Export of Sync.-frequency into the table and into the Excel.
- After exporting an Excel table, option to open the target directory.
- "Target"-button in the calibration panel.

- Batch operations with large amounts of data and the table are optimized: instead of allocating small memory blocks many times, one large block is allocated etc.; instead of adding always 1 column to the table, many columns are added with one operation. This increases the speed much: for example, it is possible to transfer 65000 measurements to the table within a reasonable time.
- Calculations of CRI and CQS values were performed for spectra with 5 nm step which consisted of every 5th value of original measured spectra (because calculations are defined for 5 nm step via standards). Now the spectra for CRI and CQS calculation consist of averages of 5 values of original spectra. This improves stability of calculation results.
