Notes on Use<Operating Environment>• The CM-2300d should be used at ambient temperatures between 5°C and 40°C, and at a relative hu-

midity of 80% or less (35°C), without condensation. Do not use it in areas of rapid temperature change.

• Do not leave the CM-2300d in direct sunlight or near sources of heat, such as stoves etc. The internal temperature of the instrument may become much higher than the ambient temperature in such cases.

• Do not use the CM-2300d in areas where dust, cigarette smoke or chemical gases are present. Doing so may cause deterioration in performance or breakdown.

• Do not use the CM-2300d near equipment which produces a strong magnetic field (such as speakers etc.).

• The CM-2300d belongs to installation category II products (equipment which is powered by an AC adapter connected to a commercially available power).

• The CM-2300d belongs to pollution level 2 products (equipment which may cause temporary electrical hazards due to contamination or condensation or products which are used in such an environment).

• Do not use the CM-2300d at altitudes of higher than 2000 m.• This CM-2300d and the AC adaptor supplied as the standard accessory have been designed exclusively

for indoor use. Do not use this instrument outdoors. If this instrument is used outdoors, it may be dam-aged by rain or other environmental conditions.

<Measurement>• 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.

<White Calibration Plate>• The calibration data for the White Calibration Plate was measured at 23°C. To achieve the highest ac-

curacy 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.

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

<Measuring Base>• When removing the “Measuring Base”, make sure that the screws used to attach the base to the instru-

ment 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 14.)

• 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.

<Power Source>• Make sure that the power switch is set to OFF (“O”) when the CM-2300d 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%).

3

<System>• Do not subject the CM-2300d to strong impact or vibration. Doing so may cause deterioration in per-

formance 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-2300d, put it on the White Calibration Plate (CM-A145).

• The CM-2300d may cause interference if used near a television, radio, etc.• Since the CM-2300d uses a microcomputer, the LCD may go blank if it is exposed to strong static elec-

tricity. 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.

<Backup Battery>• Measured data and various settings are stored in the memory backed up by batteries. The backup bat-

teries 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.

• It is recommended to keep a backup of your important data in another recording medium using optional color data software (sold separately).

Note• The backup batteries’ model number is VL2020 (3 V).• Do not try to replace the backup batteries by yourself. Contact a KONICA MINOLTA SENSING-authorised

service facility.

Notes on Storage• The CM-2300d should be stored at temperatures of between 0 and 45°C and maximum relative humid-

ity of 80%. Do not store it in areas subject to high temperatures, high humidity, or rapid changes of temperature, or where condensation may occur. For added safety, it is recommended that it be stored with a drying agent (such as silica gel) at near room temperature.

• Do not leave the CM-2300d inside a car or in the trunk of a car. Under direct sunlight in summer, the increase in temperature can be extreme and may result in malfunction.

• Do not store the CM-2300d in areas where dust, cigarette smoke or chemical gases are present. Doing so may cause deterioration in performance or breakdown.

• Accumulation of dust inside the integrating sphere will hinder accurate measurement. Block the meas-uring port to prevent entry of the dust.

• The White Calibration Plate may become discolored if left exposed to light. Therefore, make sure that the lid is closed to prevent entry of ambient light when it is not in use.

• The Target Masks may discolor if they are left exposed to light. When they are not in use, keep them in a safe place to prevent exposure to light and to protect them from scratches and dust.

• Be sure to keep all packing materials (cardboard box, cushioning material, plastic bags, etc.). They can be used to protect the instrument during transportation to service facility for maintenance (re-calibra-tion etc.).

• If you are not going to use the CM-2300d for more than two weeks, the batteries must be removed. If the batteries are left in the instrument, leakage may occur resulting in damage to the instrument.

Zero Calibration

Zero CalibrationWhen you use this instrument for the first time or when you have initialized it, zero calibration must be performed.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.

If neither zero calibration nor white cali-bration is required, you can immediately go to the sample data screen by selecting “SKIP”.

Note• Once you skip zero calibration and go to the sample data screen, you cannot perform zero calibration unless

you turn OFF the power and turn it ON again. • 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.

Memo• 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 with the zero calibration data. • The amount of stray light may change because of dust or dirt accumulated on the optical system, temperature, re-

peated operation, or the vibration and shock exerted on the instrument. In such cases, periodic zero calibration is recommended.

[Setting Procedure]Start the procedure from the <CALIBRATION> screen.

Memo• The use of the optional Zero Calibration Box ensures more reliable zero calibration.

To use the Zero Calibration Box, remove the Measuring Base attached to the instrument. • If does not appear due to the auto power save function, it may take some time to start 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 if white calibration was performed after power ON, if zero calibration was performed after that,

white calibration must be performed again.

39

White Calibration

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

Memo• 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. In

such a case, select “SKIP”, and you can immediately go to the sample data screen.

NoteThe instrument's memory contains the calibration data for the White Calibration Plate supplied with the instrument. Thus, the White Calibration Plate bearing the same serial number as that displayed in the <CALIBRATION> screen must be used for white calibration.

Memo• Although it is not necessary to perform white calibration each time the power is turned ON, to obtain more

accurate data, it is recommended to perform white calibration immediately before measurement. • If does not appear due to the auto power save function, it may take some time to start calibration after C is pressed.

Setting a Color Difference Target Data

Setting a Color Difference Target DataTo measure the color difference between two specimens, the color of one of the specimens must be set as target data. Sample data are linked to this target data and saved. Consequently, you need to select one target color as the target data to be linked before starting color difference measurement. This target datum is called the active target. The current active target can be confirmed on the target data screen (See page 51.). Once measurement is performed, you cannot change the target data to which sample data are linked into another target data. (The active target can be changed for each measurement.) Up to 1,700 target data can be set for color difference measurement. To set target data, follow the procedure given below.

Memo• One set of tolerances data can be set for pass/fail judgment with this instrument. (The initial tolerance value is 1.00

for all cases. For the tolerance setting procedure, refer to page 44.)

Note• You cannot change target data to sample data. • When the active target data are set to temporary data (TEMP data), the color difference changes every time the

temporary data are overwritten.• Before setting target data, you need to select measurement environment and perform white calibration. • For accurate measurement, make sure to keep measurement atomosphere such as ambient temperature constant.

Measuring a Color Difference Target DataAfter the calibration is complete, the <SAMPLE> screen (sample data screen) appears automatically. When the <TARGET> screen (target data screen) already appears, start from step 2.

MemoAs long as the target data screen has been displayed, the data displayed on the screen does not affect the procedure. The target data cannot be overwritten. It is always registered as new data.

[Setting Procedure]Start the procedure from the <TARGET> screen.

1 Turn B to select “TGT”, then press A.

T GT G T

2 Place the specimen measuring port to the specimen.

3 Make sure that is displayed, then press C (MEAS. button). The lamp will flash, the measure-ment will be taken, and the result will appear on the LCD.

Memo• Even temporary data (TEMP data) can be active target data. • If does not appear due to the auto power save function, it may take some time to start measurement after C is pressed.

4 To set the next target data, repeat steps 2 and 3.

Memo• Measurement will no longer be possible once the total number of target data and sample data reaches

1,700. In this case, delete some target data or sample data. • Measurement may not be possible even when the total number of target data and sample data is less than

1,700. For details, refer to “Deleting Data” on page 58.

Selecting a Color Difference Target DataTo measure the color difference between two specimens, the target data to be used for measurement must be selected from those set in the procedure “Setting a Color Difference Target Data”. To select target data, follow the procedure given below.

[Setting Procedure]Start the procedure from the <TARGET> screen.

1 Turn B to select a target data number, then press A. D will appear to allow you to change the number.

2 Turn B to select the desired target data number, then press A. The setting is determined and the <TARGET> screen will reappear. Rotating the navigation wheel changes the display and allows you to select the desired data number by browsing the list of data.

NoteTo make pass/fail judgment during measurement, it is necessary to set tolerances for the target data to be used. For details, refer to “Setting Color Difference Tolerances” on page 44.

43


Deleting a Color Difference Target DataFor the instructions on how to delete target data, refer to “Deleting Data” on page 58. You can do it by deleting the target data one by one, or by deleting all the target data set in the instrument at once.

Note• When target data is deleted, the tolerance setting will not be deleted. • You will not be able to view the color difference for the sample data that used the deleted target data.

44

Setting Color Difference Tolerances

Setting Color Difference TolerancesThis instrument allows you to set tolerances to the color difference target data for the sample data, in or-der to make pass/fail judgment.Only one set of tolerances can be set with this instrument. The tolerances can be set within the range of 0.01 to 19.99 with increments of 0.01.

NoteNote that changing the tolerance setting will automatically affect the results of all judgment. For example, the sample data which has been judged as passed is now judged as failed, and vice versa.

Deleting DataThere are two methods of deleting sample data or target data. One is to delete the data items displayed on the LCD one by one. The other is to delete all the data items at once.

Deleting Data One by One

On either of the sample data screen or target data screen, data currently displayed can be deleted.

MemoAfter sample data or target data was deleted, the sample data screen or target data screen displays data which has the number smaller than that of the deleted data by one. For example, when data No. 50 is deleted, the sample data screen or target data screen displays data No. 49. If data No. 49 does not exist, data No. 48 is displayed instead.

Note• Once data are deleted, they cannot be recovered. • When either sample data or target data are deleted, the data Nos. do not change.

For example, when three data, No. 1, No. 2 and No. 3, exist and data No. 2 is deleted, data No. 1 remains as No. 1, and data No. 3 remains as No. 3. No. 2 has no data and regarded as an unassigned number. During the next measurement, the sample data are assigned to No. 2. (The data are not assigned to No. 4. Data are always registered with the smallest available data No.)

• You can store only sample data to an unassigned number resulting from the deletion of sample data. Similarly, you can store only target data to an unassigned number resulting from the deletion of target data. Consequent-ly, when 1,700 data, the maximum, are saved, and No. 2 becomes unassigned because target data No. 2 was deleted, only target data measurement is possible and sample data measurement is impossible.

• When target data are deleted, the sample data linked to the target data will become absolute value data. (The link to the target data is deleted.) As a result, its color difference is no longer displayed. The target data linked to sample data will be changed only when the target data are deleted. In such a case, sample will automatically become absolute value data. In other cases, target data linked to sample data cannot be changed.



2 Turn B to select “DELETE”, then press A. “Are you sure to delete this data?” is displayed.

59



The data are deleted and preceding data are displayed.

Deleting All Data at Once

You can delete all the data at once on either the sample data screen or target data screen.



2 Turn B to select “ALL DELETE”, then press A. “Are you sure to delete All data?” is displayed.


All the data are deleted and a screen without data will appear.

Other Functions

62

Connecting to an External DeviceConnecting a PC or printer to the external output terminal on the instrument allows the transfer of data between the instrument and PC or printing of the measurement results.

Connecting a Personal ComputerConnecting a PC (PC-AT compatible) to the instrument with a RS-232C cable will allow uploading the data stored in the instrument’s memory to the PC or downloading data from the PC to the instrument. When connecting this instrument to a PC, use of the optional Color Data Software “SpectraMagic NX CM-S100w” is recommended.

MemoWhen the instrument is connected to a PC, make sure that the instrument is set in remote mode. Remote mode allows the following operations: 1. Outputting sample data and target data to the PC 2. Downloading target data from the PC For details, refer to “Switching to Remote Mode” on page 63.

Note• TEMP data (of both target and sample data) will not be output to a PC.

Consequently, when sample data linked to TEMP data of target data is output to a PC, the sample data turns into absolute value data. To use a PC to check the color difference between the absolute-value sample data and the TEMP data of target data, follow the procedure below:1)Save the TEMP data of target data on the CM-2300d (For details, refer to “Saving Temporary Data” on

page 55.), and output the saved target data to the PC.2)Use the software to link the target data output to the PC and the sample data (absolute value data) output

earlier. Then check the color difference.• The CM-2300d saves both SCI and SCE data for simultaneous SCI/SCE measurement.

When using SpectraMagic NX (CM-S100w) or other PC software to download target data to the CM-2300d, you can download the SCI or SCE data together or separately. When downloading only one type of data, dum-my data is automatically created for the data that is not downloaded. The dummy reflectance data is set to 0.01% over the entire wavelength range. When dummy data is used, the chromaticity, color difference and relative gloss values are also calculated and displayed using the dummy data.

Note• When connecting, make sure that the connectors are correctly oriented and fastened securely with screws. • Before connecting, make sure that the power to both the instrument and PC is turned OFF. • When disconnecting the cable, be sure to grip the plug or connector and pull it. Do not pull on or forcibly bend the cable.• Do not touch the connector terminals with your hand. Keep the terminals clean and do not apply excessive force to them.• Make sure that the cable has sufficient length. Tensioning the cable may cause connection failure or wire breakage.• When using a cable other than the one supplied as the standard accessory (I F-A16), make sure that the cable

conforms to “RS-232C Pin Assignment and Cable Wiring Diagram” on page 63. If it does not conform, a mal-function may occur or incorrect data may be transferred between the instrument and PC.

Principles of Measurement

Illuminating/Viewing SystemThe 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 simul-taneous SCI (specular component included) and SCE (specular component excluded) measurements.

1 IlluminationLight from xenon lamps diffuses in the in-tegrating sphere and il-luminates the specimen uniformly.

2 Receivinga: Light reflected by the

specimen is received.b:Light diffused in the

integrating sphere is received.

3 SensingLight is transmitted to the specimen-measur-ing and illumination-monitoring optical sys-tem, where the light in the wavelength range of 360 to 740 nm is di-vided into 10 nm-pitch components and signal proportional to the light intensity of each com-ponent are output to the analog processing cir-cuit.

1 Light from xenon lamps diffuses on the inner surface of the integrating sphere and illuminates the specimen uniformly.

2 a. The light reflected by the specimen surface at an angle of 8 degrees to the normal of the surface is received by the specimen-measuring optical system.

b.The diffused light in the integrating sphere is received by the illumination-monitoring optical sys-tem and guided to the sensor.

3 The light reflected by the specimen surface and the diffused light are divided into each wavelength component by the specimen-measuring optical system and illumination-monitoring optical sensor, respectively, and then signal proportional to the light intensity of each component are output to the analog processing circuit.

By using the outputs from the specimen-measuring optical system and the illumination-monitoring sen-sor for calculation, compensation for slight fluctuation in spectral characteristic and the intensity of the illumination light is performed. (Double-beam system)

75

Principles of Measurement

Simultaneous SCI/SCE MeasurementThe CM-2300d employs simultaneous SCI/SCE measurement method.With the conventional models, SCI (Specular Component Included) and SCE (Specular Component Ex-cluded) need to be switched mechanically by opening/closing the optical trap provided inside the inte-grating sphere.This means mechanical switching has to be made each time the mode is switched from SCI to SCE or vice versa, and it is not possible to start measurement in the new mode until switching is complete.With the CM-2300d, both SCI and SCE data can be obtained simultaneously by calculating the data ob-tained by two illuminantions.

Simultaneous SCI/SCE Measurement MethodTo illuminating/viewing system

specimen

Two light sources 1 and 2 are located as shown in the figure, and light source 1 flashes first.

Light source 1 is the diffused illumination type, and SCI measured data can be obtained as it flashes.

Then, light source 2 flashes next.

Light source 2 is provided for numeric control of the specular component. The data (i.e. amount of light reflected specularly from the surface of the specimen) obtained when this light source flashes and that obtained when light source 1flashed are used to calculate SCE data.

By carrying out the above measurement and calculation during a single measurement, both SCI and SCE data can be obtained simultaneously without mechanical switching that is required in the case of the con-ventional models.
