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 di a grams, 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 fi les.
•A graphing function provides easy-to-understand graphical displays of luminance and
chro ma tic i ty 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 fi les.
• 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, fl icker, 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 po si tion
(color ir reg u lar i ty).
• The graphical part of any graph or chart can be copied to the clip board 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 coeffi cients can be set (color correction coeffi cient, etc.).
• Memory data
Specifi ed parameters in memory can be displayed in data tables.
