Notes on Use
<Operating Environment>
• This instrument and the AC adapter supplied as a standard accessory have been designed exclusively
for indoor use.
• Do not leave the CM-2600d/2500d 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-2600d/2500d 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-2600d/2500d near equipment which produces a strong magnetic field (such as
speakers etc.)
• The CM-2600d/2500d belongs to installation category II products (equipment which is powered by an
AC adapter connected to a commercially available power).
• The CM-2600d/2500d 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 envi
-
ronment).
• Do not use the CM-2600d/2500d at altitudes of higher than 2000m.
• Use this instrument at ambient temperature between 5 and 40°C and relative humidity 80% or less (at
35°C) with no condensation
(*1)
. Operating this instrument outside specified temperature and humidity
range may unsatisfy its original performance.
*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
<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.
• When the Target Mask is not in use, install it on the White Calibration Plate (CM-A145) to prevent
exposure to external light.
<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 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.
<Power Source>
• 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%).
E-3
<System>
• 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.
<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 (3V).
• Do not try to replace the backup batteries by yourself. Contact a KONICA MINOLTA SENSING-authorised
service facility.
Notes on Storage
• The CM-2600d/2500d should be stored at temperatures between 0°C and 45°C, and at a relative hu-
midity of 80% or less (35°C), without condensation. Do not store the instrument in areas subject to
high temperatures, high humidity, sudden changes in temperature, or where freezing or condensation
may occur, because these circumstances may cause breakdown. It is more reliable to store the CM-
2600d/2500d with a drying agent (such as silica gel) at a temperature around 20°C.
• Do not leave the CM-2600d/2500d inside a car such as in the cab or trunk. Otherwise, the temperature
and/or humidity may go leave the allowable range for storage during midsummer or midwinter, result
-
ing in breakdown.
• Keep the packing materials used for shipment and use it to transport the CM-2600d/2500d. This pro-
tects the instrument from sudden changes in temperature, vibration, and shock.
• Do not store the CM-2600d/2500d in areas where dust, cigarette smoke or chemical gases are present.
Doing so may cause deterioration in performance or breakdown.
• Entry of dust into the measuring aperture will hinder accurate measurement. Block the measuring 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-2600d/2500d for more than two weeks, the batteries must be re-
moved. If the batteries are left in the instrument, leakage may occur resulting in damage to the instru-
ment.
E-4
Notes on Cleaning
• If the CM-2600d/2500d becomes dirty, wipe it with a soft, clean dry cloth. Never use solvents such as
thinner and benzene.
• If the White Calibration Plate becomes dirty, wipe it gently with a soft, clean dry cloth. If dirt is diffi-
cult to remove, contact the nearest service facility listed on the attached sheet.
• If the inner surface of the Target Masks or the inside of the integrating sphere get dirty, contact a
KONICA MINOLTA SENSING-authorized service facility.
• Should the CM-2600d/2500d break down, do not try to disassemble and repair it by yourself. Contact

Preparation
Inserting the Batteries
To supply power to the instrument, the AC adapter (AC-A17) or four AA-size batteries (Alkaline or Ni-
MH 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 explo-
sion 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.

ment to open it.
3
Place four AA-size batteries in the battery
chamber. Make sure that the batteries are
placed in the correct direction.
4
Align the marker on the battery cover with that
on the instrument, and slide the battery cover
to close it.
E-19
Preparation
Connecting the AC Adapter
M
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.(Rat-
ed: 5 V, 2.8 A)
• Before connecting or removing the AC adapter, make sure that power is turned OFF.
[Operating Procedure]
1
Make sure that power is OFF (i.e. the power
switch is set to “ ”).
2
Connect the AC adapter’s connector plug to
the AC adapter terminal on the rear of the in-
strument.
3
AC outlet
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
COND mode
Normal measurement mode. Measurement can be performed while the con-
ditions are changed. In this mode, up to six sets of conditions (illuminant,
observer angle, color space etc.) can be registered.
TASK mode
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.
• Before starting measurement, tasks (measurement procedure) must be down-
loaded 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 SpectraM-
agic (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:

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.)
• 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.
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.
