• The CM-3700A 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 (white-coated surface) by hand, scratch it or make it dirty.
• When not in use, Target Masks should be stored in the accessory case (CM-A156) so that they will not be
exposed to ambient light.

instrument from sudden changes in temperature, vibration, and shock.
• Do not store the CM-3700A 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-A156).
• Take care not to leave the CM-3700A for a long period of time with a target mask attached. The sample

Calibration of Reflectance and transmittance measurements
Calibration for Reflectance Measurements
After the Spectrophotometer has been switched on, zero calibration and white calibration must
be performed before spectral reflectance measurements are taken. Zero calibration is performed
using the Zero Calibration Box (which has a reflectance of 0%) to set the zero reference point for
reflectance measurements; white calibration is performed using a white calibration plate (which
has a reflectance of approximately 100% and for which spectral reflectance data are provided as
white calibration data) to set a high-reflectance reference point for reflectance measurements.
White calibration data
The white calibration data of the White Calibration Plate are provided under the following six kinds of
measurement conditions. When the CM-3700A is purchased, these data are already set within the instrument.
• Measurement area : SAV (3 x 5 mm) / Specular component : SCI
• Measurement area : MAV (ø 8 mm) / Specular component : SCI
• Measurement area : LAV (ø 25.4 mm) / Specular component : SCI
• Measurement area : SAV (3 x 5 mm) / Specular component : SCE
• Measurement area : MAV (ø 8 mm) / Specular component : SCE
• Measurement area : LAV (ø 25.4 mm) / Specular component : SCE
Calibration for Transmittance Measurements
After the Spectrophotometer has been switched on, 0% calibration and 100% calibration must be performed
before spectral transmittance measurements are taken. 0% calibration is performed by blocking the light
path with an opaque material (a material which has a transmittance of 0%) to set the 0% reference point
for transmittance measurements. 100% calibration is performed using either air (when measuring solid
specimens) or distilled water (when measuring liquid specimens) to set a high-transmittance reference point
for transmittance measurements; in both cases (air and water) the transmittance is assumed to be 100% for
all wavelengths.
{
Since using the LAV target mask and setting the measurement area to LAV and the SCI/SCE setting
to SCI provides the most stable data for transmittance measurements, it is recommended that
transmittance measurements and calibration (both 0% calibration and 100% calibration) for transmittance
measurements be performed under these conditions.
{
The EEPROM of the Spectrophotometer has space for one set of calibration data for transmittance
measurements.
100% calibration data
Because it is necessary to set the 100% transmittance data to the CM-3700A for all wavelengths, 100%
calibration data are normally set to all wavelengths at shipment.
17
Page 20
Performing calibration
Calibration (both zero calibration and white calibration or both 0% calibration and 100% calibration) is effective only
while the Spectrophotometer remains switched on. If it is switched off and then switched on again, both zero calibration
and white calibration (or both 0% calibration and 100% calibration) must be performed before measurements are taken.
c
The calibration becomes ef fective only when being per formed under six kinds of measurement
conditions. Therefore, for example, when performing the measurement of SCI and SCE alternately,
performing the measurement by switching the measurement area in a sequential order, or by switching
the UV light quantity, if you perform zero calibration and white calibration (0% calibration and 100% of
calibration) in advance as to up to six kinds of necessary measurement conditions, you do not have to
perform calibration every time the measurement conditions are changed. However, to more accurately
perform measurement, it is recommended to perform zero calibration and white calibration (0%
calibration and 100% calibration) every time measurement conditions are changed.
c
When the calibration has been performed under the seventh kind of measurement conditions, the oldest
calibration becomes ineffective and the calibration performed under the seventh kind of measurement
conditions becomes effective as the latest. Moreover, when the calibration is re-performed under
the same measurement conditions as one calibration that was already performed, not that the oldest
calibration becomes ineffective, but the calibration already performed under the same measurement
conditions becomes ineffective and the re-performed calibration becomes effective as the latest.
Example) First, zero calibration and white calibration are performed under the following six kinds of
measurement conditions in numerical order.
① Measurement area
② Measurement area
③ Measurement area
④ Measurement area
⑤ Measurement area
⑥ Measurement area

:
MAV / UV light quantity 99.9
:

In this case, the calibration can be performed under all the six kinds of measurement conditions. Moreover, the
calibration can be performed when UV light quantity is set except 99.9. However, in this case, the measured
value is calculated and output based on the nearest UV light quantity (in this example 99.9).
Next, if the calibration under the conditions
⑦ Measurement area : SAV / Specular component : SCE / Target mask : SAV / UV light quantity 99.9
is re-performed, not that the oldest calibration under the conditions ① becomes ineffective, but the
calibration under the conditions ④ , which was performed under the same measurement conditions,
becomes ineffective and the calibration under the conditions ⑦ becomes effective as the latest.
Next, if the calibration under the seventh kind of conditions
⑧ Measurement area : MAV / Specular component : SCI / Target mask : MAV / UV light quantity 90.0
is performed, the oldest calibration under the conditions ① becomes ineffective and the calibration under
the conditions ⑧ becomes effective as the latest. As a result, effective calibrations can be arranged in the
following chronological order.
② Measurement area : MAV / Specular component : SCI / Target mask : MAV / UV light quantity 99.9
③ Measurement area : LAV / Specular component : SCI / Target mask : LAV / UV light quantity 99.9
⑤ Measurement area : MAV / Specular component :
⑥ Measurement area : LAV / Specular component :
⑦ Measurement area : SAV / Specular component :
⑧ Measurement area : MAV / Specular component : SCI / Target mask : MAV / UV light quantity 90.0
{
The measured values are affected by UV light quantity to some extent. If you want to perform rigorous
measurement, after changing the UV light quantity, zero calibration and white calibration (0% calibration
and 100% calibration) should be performed. When performing the fluorescent measurement that does
not require rigorous measured values, the measurement should be performed with the UV light quantity
of 99.9.

{
Due to temperature changes in the surrounding environment and heat generation caused by repeated
applications, the indicated values may subtly deviate, but if the calibration is regularly performed, the
measurement accuracy will improve.

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%

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 UV light quantity using the
software.
Procedure
Open the cover of the transmittance chamber.
1.
Place the specimen against the illumination
2.
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 position, the illumination/observation geometry is
diffuse illumination/0° vowing 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.
c
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-3700A. 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 its 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.

How to remove / attach the Light Trap
{
Before removing or attaching the Light Trap, be sure to set the specular component to SCI using the
software.
Removing Light Trap
If the specimen for transmittance

measurements cannot be positioned because
the light trap is in the way, the light trap
can be removed by turning the screw of the
light trap counterclockwise, removing the
screw, and then removing the light trap.
Replacing Light Trap
To replace the light trap, hook the flange of
1.
the light trap into the Spectrophotometer as
shown, inset the screw, and turn the screw
clockwise until snug.
About haze measurements
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 aperture, the measurement geometry 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-3700A allows you to select a target mask from three types: LAV (for ø25.4mm measurements),
MAV (for ø8mm measurements) and SAV (for 3×5mm measurements), according to the specimen and your
application. Select and attach a suitable target mask (illumination area) for each measurement area.
Target Mask
Each target mask is equipped with pins at the bottom of the target mask plate; the number and position of
these pins indicate to the Spectrophotometer which target mask is attached (and thus which illumination
area is being used). However, changing the target mask does not automatically change the measurement
area of the Spectrophotometer. Therefore, when changing the target mask, follow the direction of the color
conditioning software CM-S100w.
The target mask for SAV measurements is essentially the same as the one for MAV measurements, but
with a 0.3 mm-thick diffusion plate attached to increase the illumination area and reduce the edge-loss error
which occurs with semitransparent specimens.
The target mask surface which faces into the integrating sphere has a high-reflectance white coating. Since
the reflectance of this coating affects measurements, be careful to protect the white surface from scratches
and never touch the white surface.
Measurement Area
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.

Fluorescent Measurement
The Spectrophotometer is equipped with a UV cutoff filter positioned in front of the pulsed xenon arc lamp.
The position of this filter is controlled by a motor and allows the amount of UV included in the illumination
to be controlled. When the pulsed xenon arc lamp is completely blocked by the UV cutoff filter, all light at
wavelengths below 390 nm is eliminated from the illumination. The position of the filter can also be adjusted
to provide illumination which closely matches CIE illuminant D65.
UV Adjustment
The position of the filter (and thus the amount of UV included in the illumination)
can be adjusted in 1000 steps, from 0.0 to 99.9% by software.
For the highest possible accuracy when measuring fluorescent specimens, fluorescent
calibration using a standard specimen for which standard values should be performed by
measuring the standard specimen repeatedly and the position of the UV filter adjusted so that
the measured values closely match the standard values. In addition, since the xenon lamp will
age and the light output by the lamp will change over time, it is recommended that fluorescent
calibration be performed periodically if fluorescent specimens will be measured.
WHEN FLUORESCENT CALIBRATION IS PERFORMED
When SpectraMagic™NX is used, the following four fluorescent calibration methods
are available to enable accurate measurement of fluorescent reflectance.
1. 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).
2. Whiteness (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).
WHEN FLUORESCENT CALIBRATION IS NOT PERFORMED
If extremely high accuracy is not required and fluorescent calibration will not be performed, it is
recommended that fluorescent specimens be measured with the UV filter completely removed
from in front of the xenon lamp, allowing 99.9% of UV to be included in the illumination.
