Notes on Use

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 CF-300 at an ambient temperature between 15°C and 30°C and relative humidity 80% or less (at 30°C,
with no condensation.) Be sure to use the instrument within this range. Do not use it in areas of rapid tempera-
ture changes.
• Do not leave the CF-300 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 CF-300 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 CF-300 near equipment which produces a strong magnetic field (such as speakers, etc.).
• The CF-300 belongs to installation category I products (equipment which is powered by an AC adapterconnected
to commercially available power).
• The CF-300 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 CF-300 at altitudes higher than 2,000 m.
• The CF-300 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 measure-
ment should be performed at 23°C.
• Do not allow the White Calibration Plate to get scratched or stained with such as fingerprints.
• 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.
• Do not damage or smudge the White Calibration Plate with fingerprints or otherwise.
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 (CF-A25) so that they will not be exposed to
ambient light.
