• Do not use the CM-3600A at altitudes higher than 2,000 m.
• The CM-3600A and the AC adapter supplied as a standard accessory have been designed exclusively for
indoor use. They should never be used outdoors because rain or other factors may damage the instrument.
Measurement
• Make sure no dirt or dust get into the specimen measuring port.
• When using the instrument for long periods of time, the measurement 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 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 with such as fingerprints.
• Do not move the White Calibration Plate while it has been caught by the sample holder. Doing so may
damage the White Calibration Plate.
• When the White Calibration Plate is not in use, be sure to close the cover so that the White Calibration
Plate is not exposed to ambient light.
Target Mask
• Do not touch the Target Mask's inner surface (black-coated surface) by hand, scratch it or make it dirty.
• When not in use, Target Masks should be stored in the accessory case (CM-A215) so that they will not be
exposed to ambient light.
Power Source
• Make sure that the power switch is set to OFF (" I ") when the CM-3600A is not in use.
• Always use the AC adapter supplied as a standard accessory (AC-A308) and connect it to an AC outlet of
the rated voltage and frequency.
• Use an AC power supply of the rated supply voltage (within ±10%).
• Do not connect the AC adapter to an overloaded electrical circuit. In addition, do not wrap or cover the AC

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 a breakdown. It is recommended to store the CM-3600A with a drying
agent at a temperature around 20°C.
• Do not leave the CM-3600A inside a car such as in the trunk. Otherwise, the temperature and/or humidity
may exceed the allowable range for storage during midsummer or midwinter, resulting in a breakdown.
• Keep the packing materials used for shipment and use them to transport the CM-3600A. This protects the
instrument from sudden changes in temperature, vibration, and shock.
• Do not store the CM-3600A in areas where dust, cigarette smoke or chemical gases are present. Doing so
may cause deterioration in performance or a breakdown.
• Entry of dust into the specimen measuring port will hinder accurate measurement. When the instrument
is not in use, you must close the transmittance chamber cover and cover the instrument with the supplied
Dust Cover to prevent the entry of dust into the integrating sphere.
• The White Calibration Plate may become discolored if left exposed to light. Therefore, make sure to close
the cover when it is not in use so that the White Calibration Plate is not exposed to ambient light during
storage.
• 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. And store them in the
accessory case (CM-A215).
• Take care not to leave the CM-3600A for a long period of time with a target mask attached. The sample
holder may stick to the target mask.
• 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 the service facility for maintenance (re-calibration
etc.).
Notes on Cleaning
⿎
• If the CM-3600A becomes dirty, wipe it with a soft, clean dry cloth. Never use solvents such as thinner or

Performing 100% calibration
Two methods for performing 100% calibration for
transmittance measurements are possible:
• 100% calibration to air:
When the specimen to be measured is in sheet or solid
form, 100% calibration should be performed with the
transmittance chamber empty.
• 100% calibration to water:
When the specimen to be measured is in liquid form
and will be measured using a cell (optional accessory),
100% calibration should be performed using distilled (or
pure) water in the same size and type cell as will be used for measurements.
○
Before starting transmittance calibration and measurements, attach the LAV (ø25.4 mm) target mask and
○
position the white calibration plate at the reflectance measuring port.
○
Before starting transmittance calibration and measurements, set the measurement area to LAV and the
○
specular component to SCI using the software.
○
Before starting transmittance calibration and measurements, set the same UV light quantity as when
○
performing measurements using the software.
In the fluorescent measurement that does not require rigorous accuracy (that does not perform fluorescent calibration),
perform measurement under the condition that the UV cut-off filter does not cover the xenon lamp (UV light quantity is 99.9).
After setting up the instrument as described below for your selected 100% calibration method, perform 100%
calibration from your software.

Setting a Specimen
WARNING
Do not use the CM-3600A in places where flammable or combustible gases (gasoline fumes, etc.)
are present. Doing so may cause a fire.
Do not disassemble or modify the CM-3600A. Doing so may cause a fire or electric shock.
The CM-3600A should not be operated if it is damaged, or smoke or strange odors occur. Doing so
may result in a fire.
In such situations, turn the power OFF immediately, disconnect the AC adapter from
the AC outlet, and contact the nearest Konica Minolta-authorized service facility.
CAUTION
Do not perform measurement with the specimen measuring port directed
towards your face. Doing so may cause damage to your eyes.
Be careful around openings in the CM-3600A. Failure to do so
may result in fingers being trapped causing injury.
Reflectance measurement P. 22
To measure the reflectance of a film - or
plate-like specimen, the specimen needs
to be secured with the sample holder. If the
specimen cannot be secured in this way,
remove the sample holder and hold the
specimen against the measurement aperture.

Memo
• When checking the measuring point while you are
seated, position the viewfinder cover at the desired
angle so that the image reflected in the mirror
inside the viewfinder cover can be observed .
• When the viewfinder cover is opened, the
specimen will be illuminated for 60 seconds by a
lamp to enable you to check the measuring point.
○Do not exert excessive force on the
viewfinder cover while it is open.
○It is not possible to perform measurement
if the viewfinder cover is open.
Adjust the position of the specimen
4.
so that the area to be measured is
centered in the measurement aperture
and then close the viewfinder cover.
○When adjusting the position of the specimen, the
sample holder must be pulled and kept open. This
will prevent the sample holder from scratching
the surface of the specimen during adjustment.

window tightly. (When measuring a liquid
specimen, the specimen container must be
placed against the illumination window.)
○The specimen must be placed so that
the area to be measured entirely covers
the entire illumination window.
Memo
• Although the specimen can be plaied in front of either the
illumination or receiving window, it is reccommended
that it is placed in front of the illumination window.
In this posit ion, the il lumi nati on/obse rvat ion
geometry is diffuse illumination/0° viewing angle.
In the position in front of the receiving window, the
illumination/observation geometry is approximately 0°
:0° . It does not strictly satisfy the difinition of sush as
CIE No.15. However, this presents no problem if the values are used as relative values.
• It is recommended that the optional Transmittance Specimen Holder CM-A96 be used to hold the specimen in place.
• In the case of a liquid specimen, use of an optional cell (CM-A97 to 99, A130 to 132) is recommended.
○If you are going to use a container other than the above cells, it must be transparent and constructed in such
a way that it can be positioned with opposing surfaces parallel to both illumination and receiving windows.
○Take care not to spill the liquid specimen on the CM-3600A. Should there be any spillage, immediately wipe
it with a soft, dry cloth.
○Never measure flammable liquids.
○No measurements must be performed if the specimen or inside and outside of the specimen container is
scratched or dirty. If you hold the measuring surface of the specimen with your fingers, it will be marked with
fingerprints, so always hold another part of the specimen when setting it in place.
○Air bubbles on the inner surface of the specimen's container will hinder correct measurements, so make
sure that all air bubbles are removed before measurement. (Air bubbles sometimes develop even if the
container is just left standing still.)
○Correct measurements will be hindered if water drops develop on the specimen or its container due to
condensation.
○Liquids containing particles may cause unstable measurements due to precipitation of the particles.

About haze measurements
⿎
When the White Calibration Plate is positioned over the
reflectance measuring aperture, the measurement geometry
for transmittance measurements becomes di:0°. When the
Zero Calibration Box is positioned over the reflectance
measuring aper tu r e , the measure m e n t geometr y for
transmittance measurements becomes de:0°.
The illumination/observation system does not strictly satisfy the definition of haze (ASTM D 1003).
However, this presents no problem if the values are used as relative values.
When using the optional Color Management Software SpectraMagic™ NX, these two types of transmittance
measurements (di:0°, de:0°) with and without specimen can be taken and haze can be calculated.

Illumination and Measurement Areas
The CM-3600A allows you to select a target mask from three types: LAV (for ø25.4mm measurements),
MAV (for ø8mm measurements) and SAV (for ø4mm measurements), according to the specimen and your
application. Select and attach a suitable target mask (illumination area) for each measurement area.
Target Mask
⿎
Since the CM-3600A has no target mask detection function, it is not possible for the instrument to
determine which target mask has been attached. Thus, when switching from one target mask to another,
be sure that the intended target mask is attached and the instrument is properly set from the software.
Furthermore, since the target masks are coated in black and measurement is influenced by the
condition of this coated surface, do not touch this surface with your hands, scratch it or make it dirty.
Measurement Area
⿎
When the measurement area is switched from one to another, the condensing lens of the receiving optical
system is moved by the motor according to the commands from the software running on a personal computer.

Overview of Simultaneous Measurement of SCI/SCE
The CM-3600A offers simultaneous measurement of SCI (specular
component included)/SCE (specular component excluded).
With conventional models, SCI and SCE are switched mechanically by opening and closing an optical trap
provided on the integrating sphere. This conventional method requires mechanical switching whenever SCI
and SCE need to be switched. In addition, it is not possible to start measurement until switching is completed.
The CM-3600A has eliminated mechanical switching and enables acquisition of SCI and SCE
data by performing calculations with the measured data obtained using two light sources.

Fluorescent Measurement
The CM-3600A incorporates two types of xenon lamps as light sources for fluorescent measurements
(UV full light source and UV cut light source) and performs numeric calculation of the reflectance
when the specimen is illuminated by these two light sources to obtain fluorescent reflectance.
WHEN FLUORESCENT CALIBRATION IS PERFORMED:
⿎
When SpectraMagic™NX is used, the following four fluorescent calibration methods
are available to enable accurate measurement of fluorescent reflectance.
1. Profite mode
Correction coefficients for fluorescent measurement are obtained based on the calibrated reflectance profile of
the fluorescent standard plate (the reflectance profile is created by entering reflectance for each wavelength).
2. Tint mode
Correction coefficients for fluorescent measurement are obtained so that the measured
CIE Tint value for the fluorescent standard plate is within the specified range (Tint value
for the fluorescent standard plate calibrated with a D65 light source is entered) .
3. Whiteness (WI) mode
Correction coefficients for fluorescent measurement are obtained so that the measured CIE
WI (whiteness index) value for the fluorescent standard plate is within the specified range (WI
value for the fluorescent standard plate calibrated with a D65 light source is entered).
4. Tint and WI mode
Correction coefficients for fluorescent measurement are obtained so that the measured CIE Tint
and WI values for the fluorescent standard plate are both within the specified range (Tint and
WI values for the fluorescent standard plate calibrated with a D65 light source are entered).
CALCULATING FLUORESCENT REFLECTANCE
⿎
Based on the measured reflectances for the fluorescent standard plate obtained under the UV full light
source and under the UV cut light source, the amount of fluorescence is obtained. The correction coefficients
for fluorescent measurement are then determined so that the given reference values are satisfied.
(Calibration example: Profile mode)
Under UV full light
source
Under D65 light source
(entered reference value)
Under UV cut light
source
These correction coefficients are then used to obtain the fluorescent reflectance by performing numeric
calculations using the measured reflectances under the UV full light source and under the UV cut light source.
(The reflectances at cut wavelengths under UV cut light source are set to 0%.)
As a result, the CM-3600A can keep the fluorescent output quantity as close
to the standard as possible, without the need for adjusting the quantity of
ultraviolet light, which is required in the case of conventional models.

The UV full xenon lamp of the CM-3600A has a spectral distribution similar to that of the D65
light source. Therefore, when high-accuracy fluorescent measurements are not required,
normal measurement of reflectance can be used to measure fluorescent reflectance.
UV CUT LIGHT SOURCES
⿎
With the CM-3600A, UV400 cut light source (with radiation at wavelengths of 390 nm or lower eliminated)
and UV420 cut light source (with radiation at wavelengths of 410 nm or lower eliminated) are provided.
