JETI LiVal Changelog

Version history of JETI LiVal (Last updated on April 17, 2020)

V6.16.3

[CHANGED]
- company address

[BUGFIX]
- the spectral weighting function could be shifted if the wavelength ranges do not match the measured spectrum -> fixed

V6.16.2

[CHANGED]
- Mode designator in saved (or user created) reference files is not case-sensitive anymore. The same for "MODEL". (For lamp files, the mode was already not case-sensitive).

[BUGFIX]
- "Choose Standard Illuminant"-utility showed false settings if called before an RGB-Widget has been displayed somewhere. -> fixed

V6.16.0

[NEW]
- Export as PDF report
- Museum Lighting Damage - widget
- Color Difference Widget (CIE76, CIEDE2000)
- Save as .CSV and .SPC: information about hazard calculation and museum lighting damage modes can be saved (to make calculations correctly if loading). Checkboxes in the "Save" window.
- TM-30-18 standard (replaced TM-30-15); Color Vector Graphic (CVG) widget correspondingly updated
- Hazard: measuring mode and viewing angle are saved for every measurement. This information is exported into the table and in Excel.
- and + shortcuts to switch presets
- Basic device parameters are logged in an individual file named by device number.

[CHANGED]
- Maximum number of points for xy-polygons supported by Pass/Fail and Rank View increased to 15.
- New custom made message boxes with icons.
- Behaviour of transferring of measurements to table, saving them as reference and building a PDF-report from them is unified. Three buttons below the legend instead of menu items.
- "Measuring mode"-drop-down-list appears only in offline mode. With device connected, the mode is displayed inside the "Measurement" button.
- 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.

[BUGFIX]
- 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
- Calibrations which have zeroes could cause crash -> fixed
- Laser intensity has not been changed if applying focusing optics to a spectraval device. -> fixed

V6.14.3

[BUGFIX]
- The spectral weighting function could be shifted if the wavelength ranges do not match the measured spectrum. -> fixed

V6.14.2

[BUGFIX]
- Setup and Program where not digitally signed -> fixed

V6.14.1

[NEW]
- Import from SD-card - files are deselected in the list during operation.
- Import from SD-card - It is possible to cancel operation by closing of the progress bar.

[BUGFIX]
- Import from SD-card - opening of other windows or applications during import caused LiVal to look like a crash ("no response" etc.). -> fixed

V6.14.0

[NEW]
- 2 custom presets added
- Preset-Backward and Preset-Forward arrow buttons
- Functions Ssc, Slc, Smc, Smel, Srh (circadian norm 2018), CIE1931 and CIE1964 x,y,z in distribution
- "ipRGC-Influenced Responses to Light" widget (5 curves; 5 corresponding values)
- History widget: view of total time
- Menu/Options/TM-30-15. Show Rf&Rg in the angled chart on/off, precision and font size
- Treating of adaption failure error in case of continuous mode. Creating of empty measurements marked red in the legend

[CHANGED]
- Minimum value of sync.-frequency numeric control is now 0.1 Hz. If setting to a frequency < 16 Hz fails because of hardware restrictions, it is set to 16 Hz
- Integration time < 1 ms for specbos1211 devices equipped with corresponding hard- and firmware is supported

[BUGFIX]
- Saving of a calibration to device didn't always work with boudrate=3000000. -> fixed
- If sensor mode is switched to "Sensor disabled" and then back to "Sensor active", a message box came that the measuring mode has been changed anyway. -> 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

V6.12.0

[NEW]
- Two widgets for L*u*v* color space: L*u*v* and sC*h.
- "Spectral Calculation" widget: Lv, x, y values of the calcualtion result spectrum.
- Continuous mode - schedule: possibility to set start and end time, a break and periodicity of continuous measurement.
- Capture: streaming of continuously measured spectra into a file for security with very long continuous measurement series.
- History-chart: possibility to click on some data point to jump to corresponding measurements in the legend.
- History-chart: x-axis can have sense of absolute time or of measurement number (switch).
- Offline mode: if there are no measurements and the user tries to open a reference file in another measuring mode than the current, the current measuring mode is automatically switched.
- 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.

[CHANGED]
- 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.

[BUGFIX]
- Blue cursor in xy- and u'v'-charts was invisible if zoomed in to blue -> fixed (cursors are black now)
- Offline mode: table was not reinitialized if measuring mode has been changed. -> fixed
- Raw spectrum: wavelength and a value on it stood dimmed even after a successful measurement. -> fixed
- Table: memory errors have not been treated. -> fixed

- Load SPC with many measurements - memory error due to unnecessary amounts of allocated memory. -> fixed

V6.8.2

[BUGFIX]

- Loading of SPC - time localizing made timestamp false. -> fixed
- Tab-order in "Select Measurements to Be Saved"-window was wrong. -> fixed
