Light Measurement Data Management Software
This light measurement data management software downloads measurements from a
multimedia display tester (3298/3298F) to a PC and displays data tables,
chromaticity diagrams, deviation charts, and trend graphs. The program can also read
data stored in the display tester's memory.
• The program can be used to display data for each measurement parameter in table format
and save the data to text files.
• A graphing function provides easy-to-understand graphical displays of luminance and
chromaticity measurements according to the particular management application.
• Diagrams such as chromaticity diagrams can be copied and pasted to other Windows
programs using the Windows clipboard.
• Diagrams such as chromaticity diagrams can be printed out as hard copies.
• Setting parameters can be saved to files.
• Memory data can be loaded into tables.
Functions
• Data table (measurement data)
Displays data for each measurement parameter in table format.
Any of the available parameters can be selected for display.
• Trend graph
Displays trends for luminance, flicker, and chromaticity.
The number of measurements is shown on the horizontal axis.
• Chromaticity diagram
Displays chromaticity measurements (x, y/u’, v’ table color system) in graph format. The
screen size of the chromaticity diagram can be switched between two different
sizes.Three different plot modes are available: refresh, trace, and scatter.
• Deviation chart
Up to six reference colors can be set for chromaticity measurements.
Reference colors can be input numerically or through measurements.
Three different plot modes are available: refresh, trace, and scatter.
• Surface distribution graph
Displays deviations for luminance and chromaticity according to position
(color irregularity).
• The graphical part of any graph or chart can be copied to the clipboard as a bitmap.
• The graphical part of any graph or chart can be printed.
• File saving
Information shown in a data table can be saved in text format.
• Settings
Various coefficients can be set (color correction coefficient, etc.).
• Memory data
Specified parameters in memory can be displayed in data tables.
