Be sure to use this instrument properly. Use of this instrument in ways other than those speciﬁed in

this manual may result in risk of injury, electric shock, instrument damage, or other problems.

Operating Environment

• Use the CM-3700A at an ambient temperature between 13°C and 33°C and relative humidity 80% or less (at

33°C) with no condensation. Be sure to use the instrument within this range. Do not use it in areas of rapid

temperature changes.

• Do not leave the CM-3700A 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-3700A in areas where dust, cigarette smoke or chemical gases are present. Doing so

may cause deterioration in performance or a breakdown.

• Do not use the CM-3700A near equipment which produces a strong magnetic ﬁeld (such as speakers, etc.).

• The CM-3700A belongs to installation category I products (equipment which is powered by an AC adapter-

connected to commercially available power).

• The CM-3700A belongs to pollution degree 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-3700A at altitudes higher than 2,000 m.

• 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.

Power Source

• Make sure that the power switch is set to OFF (“ I “) when the CM-3700A 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

adapter with cloth or other material while in use. Doing so may cause an electric shock or ﬁre.

System

• Do not subject the CM-3700A to strong impact or vibration. Doing so may cause deterioration of perfor-

mance or breakdown.

• The specimen measuring port and integrating sphere are extremely precise components, and great care

should be taken to prevent them getting dirty or exposing them to impacts. When the CM-3700A is not in

use, be sure to attach a target mask to the measuring port to prevent entry of foreign matter.

• The CM-3700A may cause interference if used near a television, radio, etc.

• Since the CM-3700A uses a microcomputer, external magnetic noise may cause malfunction. In this case,

turn the power OFF, and wait 30 minutes, and then turn it ON again.

About Transmittance Measurement

• Do not spill a specimen or other liquid on the instrument. If any liquid is spilled on the instrument, wipe it off

immediately with a soft, dry cloth.

Notes on Storage

• The CM-3700A should be stored at temperatures between 0°C and 40°C, and at a relative humidity 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 a breakdown. It is recommended to store the CM-3700A with a drying

agent at a temperature around 20°C.

• Do not leave the CM-3700A 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-3700A. This protects the

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

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

• If the CM-3700A becomes dirty, wipe it with a soft, clean dry cloth. Never use solvents such as thinner or

benzene.

• If the White Calibration Plate becomes dirty, wipe it with a soft, clean dry cloth. If dirt is difﬁcult

to remove, wipe it off with a cloth dampened with commercially-available lens cleaning solution.

Then remove the solution with a cloth dampened with water, and leave the plate to dry.

• If the inner surface (white-coated surface) of the Target Masks, or the inside of the integrating sphere, get-

dirty, contact a Konica Minolta-authorized service facility.

• Should the CM-3700A break down, do not try to disassemble and repair it by yourself. Contact a Konica

Minolta-authorized service facility.
