*1 Operating temperature/humidity range of products for North America: between 5 and 40°C and relative humid-

ity 80% or less (at 31°C) with no condensation

• When using the instrument upside-down, make sure no dirt or dust get into the aperture.

• When using the instrument for long periods of time, the displayed value may change depending on changes in the environment. Therefore, in order to achieve accurate measurements, we recommend that white calibration be done regularly using the White Calibration Plate.

• The calibration data for the White Calibration Plate was measured at 23°C. To achieve the highest accuracy when measuring absolute values (colorimetric values), calibration and measurement should be performed at 23°C.

• Do not allow the White Calibration Plate to get scratched or stained.

• If you are not going to use the White Calibration Plate, attach the cap to the White Calibration Plate to prevent entry of ambient light.

• Do not touch the Target Mask’s inner surface by hand, scratch it or make it dirty.

• When the Target Mask is not in use, install it on the White Calibration Plate (CM-A145) to prevent exposure to external light.

• When removing the “Measuring Base”, make sure that the screws used to attach the base to the instrument are stored properly and are not mislaid. If the screws do become mislaid, use M3 cross-headed screws that are 4 to 5 mm long as replacements. (For details, see page E-16.)

• Do not tighten the screws too tightly when attaching the “Measuring Base”. This could damage the “Measuring Base” or the instrument itself.

• Remove the “Measuring Base” before using the optional Zero Calibration Box or Dust Cover Set.

• Make sure that the power switch is set to OFF (“O”) when the CM-2600d/2500d is not in use.

• Always use the AC adaptor (AC-A17) supplied as a standard accessory and connect it to an AC outlet of the rated voltage and frequency. Use the AC power supply voltage of the rated supply voltage (with in ± 10%).

• Do not subject the CM-2600d/2500d to strong impact or vibration. Doing so may cause deterioration in performance or breakdown.

• Since the specimen measuring port and integrating sphere are extremely precise optical components, great care should be taken to prevent them getting dirty or exposing them to impact. If you are not go ing to use the CM-2600d/2500d, put it on the White Calibration Plate (CM-A145).

• The CM-2600d/2500d may cause interference if used near a television, radio, etc.

• Since the CM-2600d/2500d uses a microcomputer, the LCD may go blank if it is exposed to strong static electricity. In this case, turn the power OFF, then turn it ON again. If black smudges appear on the LCD, wait until they disappear naturally.

• When turning the power OFF and then ON again, wait several seconds after turning the power OFF.

• Measured data and various settings are stored in the memory backed up by batteries. The backup batteries are automatically charged during operation of this instrument, and can retain the contents of the memory for 4.5 months if they have been fully charged. At the time of purchase, the backup battery may not be fully charged. To charge the backup battery, set the power switch to ON. Charging of the backup battery is performed continuously while the instrument is switched on, even while the instru ment is being used. Full charging is completed in 25 hours, and there is no danger of overcharging.

This section explains how to clean the White Calibration Plate, Target Mask and inside of the integrating sphere.

White Calibration Plate

Gently wipe off dirt with a soft dry cloth. If dirt is difficult to remove, dampen a cloth with commercially available lens cleaning liquid and wipe. Then remove the liquid with a cloth dampened with water, and leave it to dry.

Note

Take care not to scratch the White Calibration Plate.

Target Mask

Use a blower to remove dirt and dust from the Target Masks.

Note

Do not touch the inner surface of the Target Masks with your fingers or wipe them with a cloth. If the Target Masks are so dirty that dirt cannot be removed with a blower, contact the nearest KONICA MINOLTA SENSINGauthorized service facility.

Inside the Integrating Sphere

emo

For attaching/removing a Target Mask, refer to “Attaching/Removing a Target Mask” (page E-14).

1. To prevent dust and dirt entering the optics sec-

tion from the integrating sphere, slide the viewfinder lever to open the viewfinder.

2. Remove the Target Mask.

3. Use a blower to remove dirt and dust from the in-

tegrating sphere.

Note

Do not touch the white-coated inner surface of the integrating sphere, wipe it with a cloth or put any object inside it. If the surface is so dirty that dirt cannot be removed with a blower, contact the nearest KONICA MINOLTA SENSING-authorized service facility.

Preparation

Inserting the Batteries

To supply power to the instrument, the AC adapter (AC-A17) or four AA-size batteries (Alkaline or NiMH battery is recommended for better service life) must be used. Use either the AC adapter or batteries, according to which suits your application.

Note

• If you are not going to use the instrument for more than two weeks, make sure that the batteries are removed. If the batteries are left in the instrument for long periods of time, battery electrolyte may leak and damage the instrument.

• Do not use batteries of different types or mix new batteries with old ones. Doing so may result in battery explosion or reduction of battery life.

• Do not touch or short-circuit the terminals inside the battery chamber. Doing so may result in breakdown of the instrument.

[Operating Procedure]

Make sure that power is OFF (i.e. the POWER

switch is set to “ ”).

Slide the battery cover on the rear of the instru-

ment to open it.

Place four AA-size batteries in the battery

chamber. Make sure that the batteries are placed in the correct direction.

Align the marker on the battery cover with that

on the instrument, and slide the battery cover to close it.

Preparation

Connecting the AC Adapter

emo

Use of the AC adapter (AC-A17) rather than batteries is recommended, since more power will be required when the external output terminal is used to output data to an external device or print it.

Note

• To supply AC power to the instrument, always use the AC adapter (AC-A17) supplied with the instrument.(Rated: 5 V, 2.8 A)

• Before connecting or removing the AC adapter, make sure that power is turned OFF.

[Operating Procedure]

Make sure that power is OFF (i.e. the power

switch is set to “ ”).

Connect the AC adapter’s connector plug to

the AC adapter terminal on the rear of the instrument.

Insert the AC adapter’s power plug to an AC

outlet (100-240 VAC, 50-60 Hz).

Items You Must Know

Language Mode

Contents on the LCD screen can be displayed in English, Japanese, German, French, Spanish or Italian. In this manual, explanation of operating methods and display is given for English mode.

Measurement Mode

Two measurement modes (COND and TASK) are available with this instrument, and can be switched from one to another.

Measurement Mode Application

Normal measurement mode. Measurement can be performed while the con-

COND mode

TASK mode

ditions are changed. In this mode, up to six sets of conditions (illuminant, observer angle, color space etc.) can be registered.

Special measurement mode. For continuous inspection, this mode allows you to perform measurement while messages indicating the measurement procedure are displayed on the LCD. The messages can be created by use of the previously used software SpectraMagic (Ver.3.2 or higher; except for Ver. 3.5) with your PC. In this mode, color differences can be calculated one by one against up to 10 color difference target data.

Note

• Before starting measurement, tasks (measurement procedure) must be downloaded from the PC using SpectraMagic (Ver.3.2 or higher; except for Ver.3.5). TASK mode cannot be selected if no tasks have been downloaded.

• During TASK mode, only the data measured last is displayed. Use of SpectraMagic (Ver.3.2 or higher; except for Ver.3.5) allow you to access to previous data in the memory.

Up to six sets of conditions can be registered either in COND or TASK mode.

In the case of COND mode:

E-22

Items You Must Know

Target Modes

• The CM-2600d/2500d supports two Target Modes, “defined in COND.” mode and “linked to each data.” mode, to analyze both measurement data and color difference. As with Language Mode and Measurement Mode, you can select the desired mode when you turn the power ON.

• The default setting is “linked to each data.” mode. To switch to “defined in COND.” mode or switch between the target modes, you need to follow the procedure to select target mode.

• Depending on the target mode selected, the display and the procedure for some operation for the instrument are different. Below are some examples of these differences. (For details, see Target Mode in the Appendix.)

Note

Once the target mode is changed, previous data will be cleared. It is recommended that you save previous data into other storage media in advance by using the Color Data Software that is optionally available.

• In “linked to each data.” mode, the next color difference data number is displayed next to the currently selected color difference data number in the initial settings screen. When “defined in COND.” mode is selected, it is not displayed.

• In “linked with each data” mode, to display the color difference for measurement data, you can only select the color difference for the currently selected measurement data. When “defined in COND.” mode is se lected, you can freely select the color difference data number after making measurements. You can also display the results of the selection.

• Data storage capacity for the “linked to each data.” mode is 1700 pieces, and that for the “defined in COND.” mode is 700 pieces.

Zero Calibration

When you use this instrument for the first time or when you have initialized it, zero calibration must be performed. Zero calibration is also sometimes required when measurement conditions are changed. Once zero calibration is completed, the zero calibration data will be kept even if the power is turned OFF. Thus, it is not necessary to perform zero calibration each time the power is turned ON.

emo

• The effects of stray light inside the measuring part (i.e. light generated due to the flare characteristics of the optical system) will be compensated automatically by the zero calibration data.

• The amount of stray light may change because of dust or dirt which has collected in the optical system, temperature, repeated operation, vibration and shock exerted on the instrument. In this case, performing zero calibration periodically is recommended.

Note

• If the instrument is not used for long periods of time, the zero calibration data stored in the instrument may be lost. If the data is lost, zero calibration must be performed again.

• Before starting zero calibration, select the desired MASK/GLOSS setting from M/I+E, M/SCI, M/SCE, S/I+E, S/SCI and S/SCE in the <FILE> screen. If M/ ed, set SAV to the instrument. For MAV, set the lens position selector switch and Target Mask to MAV. For SAV, set them to SAV.

• Use of the optional Zero Calibration Box ensures proper zero calibration. If Zero Calibration Box is used, remove “Measuring Base”.

• If does not appear due to the auto power save function, this may be due the fact that it can take time to start zero calibration after C is pressed.

Note

• When zero calibration is complete, perform white calibration. Measurement cannot be performed if white calibration has not been completed.

• Even though white calibration has been performed after the power is turned ON, if zero calibration has also been performed after that, white calibration must be performed again.

White Calibration

White calibration must be performed prior to start of measurement after the power is turned ON.

emo

• Own calibration data has been registered to the White Calibration Plate supplied with the instrument.

• Although white calibration data is retained in internal memory even after power is turned off, it is still necessary to repeat white calibration each time you switch the power back on.

• The reading may fluctuate slightly due to changes in the ambient temperature or due to heat generation caused by repeated operation of the instrument. In this case, make sure to perform white calibration regularly.

• White calibration is not required if you just want to see the measured data without performing measurement.

Note

• White calibration must be performed at the same temperature as the one at which measurement will be performed.

• Before starting white calibration, make sure that the instrument is sufficiently acclimatized to the ambient temperature.

• Before starting white calibration, select the desired MASK/GLOSS setting from M/I+E, M/SCI, M/SCE, S/I+E, S/SCI and S/SCE in the <FILE> screen. If M/ ed, set SAV to the instrument. For MAV, set the measurement area selector switch and Target Mask to MAV. For SAV, set them to SAV.

Setting a Color Difference Target Data

To measure the color difference between two specimens, the color of one of the specimens must be set as the target color. Up to 1700 target colors can be set for color difference measurement. (700 can be set in the “defined in COND” mode.) To set a target color, follow the procedure given below.

emo

• Since tolerances for pass/fail judgment need to be set for each target color, target color data must be set before setting tolerances.

• The memory of this instrument can store up to 1700 pieces of data in total, (700 in the “defined in COND” mode). This amount includes the sample data for the COND and TASK modes as well as color difference target data. When some sample data have already been stored, the number of target colors which can be set will be reduced by the number of the sample data.

Note

• Before setting target colors, a measurement condition (COND1 to COND6) must be selected and white calibration performed.

• For accurate measurement, make sure to keep measurement conditions (ambient temperature etc.) constant.

To make pass/fail judgment during measurement, it is necessary to set tolerances for the target color to be used. For details, refer to “Setting Color Difference Tolerances” (page E-52).

Deleting a Color Difference Target Data

There are two methods for deleting target color data. One is to delete the target color data set in “T*” of the measurement conditions (COND 1 to COND 6) one by one. The other is to delete all the target color data set in the instrument.

Note

• When target color data is deleted, its tolerances will also be deleted.

• You will not be able to view the color difference for measurement data that used the deleted target color data.

[Setting Procedure]

Display the target color data to be deleted, as explained in “Setting a Color Difference Target Data”.

Turn B to select “DEL”, then press A.

Turn B to select the desired deletion method, then press A.

Deletion Method

• T* DELETE:

Setting Color Difference Tolerances

This instrument allows you to set tolerances for the measured color difference, to make pass/fail judgment. Pass/fail judgment is made based on two types of tolerances: box tolerances and elliptical tolerances. Prior to start of measurement, tolerances must be set.

emo

• Two types of tolerances are available (box tolerances and elliptical tolerances). With this instrument, either box or elliptical tolerances can be set for each target color. However, the following restrictions apply to the tolerance type that can be set, depending on the selected color space.

• In the case of “MUNSELL” and “DENSITY” as the Color Space, neither box nor elliptical tolerances can be set.

• In the case of “WI”, “YI”, “ISO BRIGHTNESS” and “WI/Tint” as the Color Space, only box tolerances can be set.

• In the case of “Spect. Graph” as the Display Mode, neither box nor elliptical tolerance can be set.

Note

Once tolerances are set, the tolerance type cannot be changed. To change the tolerance type, the currently set tolerances must be cleared.

Box Tolerance

If the measured color difference is outside the specified tolerances set for the target color, it will be highlighted to indicate that the pass/fail judgment result is FAIL. Both + and - box tolerances can be set for each target color.

Note

Target colors must be set before setting tolerances.

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. However, the pass/fail judgment is based on a standard color difference setting for the selected target color data number and the color difference. The differences between the target color data and the color difference is not always standard. The other target mode supported by this instrument, “linked to each data.”, can store the target color data number with the selected measurement data and display the results using the associated target color data number. In addition to absolute values, it can also be used for general color differences.

This section describes how the results are affected when using “linked to each data.” target mode and the specified target color data has been changed or deleted. It also compares the difference to the results dis played for “defined in COND.” target mode.

When the Color Difference Target Data No. has Been Changed

When “T” is selected in the measurement results screen, the target color screen will be changed to the currently selected number to be used for next measurement. The navigation wheel can also be used in this screen to recall a target color number that has been stored in the instrument’s memory. If “BREAK” is selected in the target color data screen, you can revert to the originally selected target color number. For details, see “Switching between the Measured Data screen and the <TARGET> screen” on page E-

49.

Select and then press A, the <TARGET> screen is displayed. It shows the target color data which number is currently selected and is used for next measurement.

Select D, press A and then turn B to the left or right, it can be switched the target color data number.

In “linked to each data.” mode, the measured data is calculated with the target data which is selected at the time of measurement and the results are displayed.

Select “BREAK” and then press A, the display return to the measurement screen. In “defined in COND.” mode, the measured data is recalculated with the new selected target color number’s data and the results are displayed.

E-75

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. If the number for the target color that was set at the time of measurement is deleted, the link between the data and target color data number is cut when the number is deleted. The measurement data is saved with information that states that there is no target color for that data, “T---” is displayed for the target color, and “-----” for the color difference and pass/fail judgment. In addition, no points appear on the graph. With “defined in COND.” the color difference and pass/fail judgments for the reset target color data and its data are recalculated based on the associated color difference.

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 reflect ance data is calculated. This gives the average data of the entire specimen.

• Auto Averaging: Specified number of measurement are repeated at the same position on the speci-

men and then the average of the measured spectral reflectance data is calculated. This will improve the accuracy of the measured data.

These two functions can be used in combination. In this case, it is necessary to make settings for both auto and manual averaging. For details, refer to “Setting a Measurement Condition” (from page E-34).

Note

For average measurement, the average of the measured spectral reflectance data is calculated first, then colorimetric data is calculated based on that calculated average. Thus, the result may not match the average of colorimetric data.

Manual Averaging

This method is used 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, to obtain the average data of the entire specimen. Set the number of measurements to be performed and the standard deviation, and then start measurement.

Note

Before starting manual averaging, make sure that the number of measurements to be performed and standard deviation are set. For details, refer to “Setting an Measurement Condition” (from page E-34).

[Setting Procedure]

This operation can be started from a screen in which “BREAK” is displayed.

Make sure that “BREAK” is highlighted, then press A.

Turn B to select “BREAK”,

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. If the target color data has been deleted, the color difference displayed for that color target and based on the tolerances for the color target cannot be performed. In addition, if other target color data is selected, recalculations and pass/fail judgments cannot take place.

Pass/Fail Judgment Based on Box Tolerances

If the measured color difference is outside the specified tolerances, it will be highlighted to indicate that the pass/fail judgment result is FAIL. Both + and - tolerances can be set for each target color. To perform pass/fail judgment based on the specified box tolerances, follow the procedure given below:

Note

To use this function, make sure that the target color to be used is set.
