Displaying the Measurement Results Measurement Results for “linked to each data.” This instrument can set multiple target color data numbers and select one of those for displaying the results for the color difference. It can also easily switch the selected target color number using the navigation wheel. The “defined in COND.” target mode can use these functions to calculate multiple color differences for measurement data, and make pass/fail judgments based on this.
Displaying the Measurement Results When the Target Color Data No. has Been Deleted If the target color data for a number is deleted, the target color for data to which that number was associated is set to that of the next highest number. The target color number is reset to that of the number for which there is a target color data number. With “linked to each data.” target-mode, the measured data is saved with target color number that was specified for it at the time of measurement.
Chapter 4 Other Functions E-77
Measuring the Average When taking measurements or setting target colors, more accurate data can be obtained if the averaging function is used. The following two averaging functions are available. • Manual Averaging: When the color of the specimen is not uniform, measurements are performed at different positions on the specimen and then the average of the measured reflectance data is calculated. This gives the average data of the entire specimen.
Measuring the Average 2 Place the specimen measuring port to the specimen to be measured, and then press C (MEAS. button). If 2 is set for “MANUAL AVG. TIMES” or if 3 or a higher value is set and the standard deviation is not below the specified one, place the specimen measuring port to the next place and then press C (MEAS. button). • The number of completed measurements including the one currently in progress and standard deviation will be displayed during measurement.
Measuring the Average Auto Averaging Measurement is repeated the specified number of times in the same position on the specimen and then the average of the measured reflectance data is calculated. This will improve the accuracy of the measured data. Set the number of measurements to be performed and the standard deviation, and then start measurement. Note Before starting auto averaging, make sure that the number of measurements to be performed is set.
Pass/Fail Judgment for Color Difference This instrument allows you to set tolerances for the measured color difference, to make pass/fail judgment. Two kinds of pass/fail judgment methods are available. One is based on the specified box tolerances, and the other is based on the specified elliptical tolerances. In “linked to each data.” mode, the number of the target color data selected at the time of measurement or the measured data are passed/failed based on the tolerances.

Principles of Measurement Illuminating/Viewing System The flow of measurement is shown below. This instrument utilizes the D/8 geometry conforming to CIE No.15, ISO 7724/1, ASTM E1164, DIN 5033 Tei17, and JIS Z8722-1982 (diffused illumination/8º viewing system) standards, and offers simultaneous SCI (specular component included) and SCE (specular component excluded) measurements. 1 Illumination Light from xenon lamps diffuses in the integrating sphere and illuminates the specimen uniformly.
Principles of Measurement Illumination Area and Measurement Area The CM-2600d allows selection of either SAV (ø3 mm) or MAV (ø8 mm) measurement area according to the specimen and applications. A Target Mask (illumination area) suitable for the selected measurement area must be installed. Note With the CM-2500d, only MAV (ø8 mm) is available. Target Mask Since this instrument does not have automatic Target Mask matched to the selected measurement area must be attached correctly.
Principles of Measurement Simultaneous SCI/SCE Measurement The CM-2600d/2500d employs simultaneous SCI/SCE measurement method. With the conventional models, SCI (Specular Component Included) and SCE (Specular Component Excluded) need to be switched mechanically by opening/closing the optical trap provided inside the integrating sphere.
Target Mode Relation Between Measured Data and Target Color • In “linked to each data.” mode, there is specific target color data associated with the selected number of the target color data at the time of measurement. • In “defined in COND.” mode, the target color data depends on the conditions.
