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%).
