Introduction
Thank you for buying a Minolta product. This instrument is a high-precision, light-weight Chroma
Meter developed for Absolute Measurement and Difference Measurement in a wide range of fields.
Measurement can be made in conjunction with a multi-functional data processor or with the Measur-
ing Head alone.
Layout of This Manual
• This manual describes the CR-400 and CR-410. The CR-400 is used for illustrations, and any
differences have been pointed out clearly so the manual may be used equally for both models.
• The manual is divided into two sections covering the Measuring Head and one section on the data
processor. See following chapters for your use.

Notes on Use
<Operating Environment>
• The CR-400/410 should be used at ambient temperature between 0 and 40 ˚C .
Do not use the instrument in areas of rapid temperature change.
• Do not leave the CR-400/410 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 CR-400/410 in areas where dust, cigarette smoke, or chemical gases are present.
Doing so may cause deterioration in performance or breakdown.
• Do not use the CR-400/410 near equipment which produces a strong magnetic field (such as speak-
ers, etc.
• The CR-400/410 is classified as an Installation Category II (equipment which is powered by an AC
adapter connected to a commercially available power source .
• The CR-400/410 is classified as a Pollution Degree 2 (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 CR-400/410 at altitudes of higher than 2000m.
• The CR-400/410 is designed for indoor use only, and should never be used outside as there is a
danger that rain and other environmental factors may damage the instrument.
<The Instrument>
• Do not subject the CR-400/410 to strong impact or vibration.
Doing so may cause deterioration in performance or breakdown.
• The measurement aperture should be protected from dirt and strong impacts. Always attach the
protective cap when not in use.
• The CR-400/410 may cause interference if used near a television, radio, etc.
• Due to the effect of electrostatic discharge on or in the vicinity of CR-400, erroneous can occur. In
this cace please repeat the last mesurement. If strong static electricity is received at the moment
measurement is made, the measurement values may be adversely affected, but the following mea-
surement will be ok.
<Measurement>
• When using the Measuring Head 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. Doing this will automati-
cally correct other calibration channels, so there is no need to calibrate them.
• Changes in the temperature will cause the color of the specimen to change, resulting in changes in
the measurement data even if white calibration has been done. Therefore, calibration, setting of
color difference target colors, and measurement should all be done at the same temperature.
• When performing continuous measurements, remove the batteries and use the AC adapter.
<Displayed Data>
• Although this instrument is designed for increased accuracy in operations by internally calculating
more digits than are actually displayed, the minimum number of digits displayed may differ by one
digit during rounding off, color space conversion, and in other situations.
<White Calibration Plate>
• The white calibration plate is placed near the middle. When doing a calibration, use the area near the
middle.
• Do not allow the white calibration plate to get scratched or stained.
• If you are not going to use the white calibration plate, close the cover to the white calibration plate
to prevent entry of ambient light, as any areas exposed to such light will discolor.

5
<Roll Paper>
• This roll paper is special paper (thermal paper which displays color as the result of a heat-induced
chemical reaction.
• Do not store in hot and/or humid places.
• Do not expose to direct sunlight, fluorescent light, or other outside light for long periods of time.
• Using roll paper which has become discolored because of the way it was stored will result in print-
ing which is difficult to read. Use new roll paper whenever possible.
• Printed data may become difficult to read because of the way the paper has been stored. We recom-
mend you copy any data for long-term storage.
<Printing>
• Since the printer uses a thermal mechanism, the ambient temperature may affect the speed and/or
consistency of print.
<Power Source>
• Make sure that the power switch is set to OFF when the CR-400/410 is not in use.
• Always use the AC adapter (AC-A17 supplied as a standard accessory and connect it to an AC
outlet of the rated voltage and frequency.
• Use an AC power source which is within 10% of the rated voltage and frequency.
<Recommended Batteries>
• A low ambient temperature will cause a drop in battery performance, with similar results for perfor-
mance in terms of number of measurements and printing speed and consistency. We therefore rec-
ommend you use lithium or nickel metal-hydride batteries which can withstand changes in tem-
perature.
<Backup Batteries>
•Measurement data and settings are stored in memory which is backed up by the internal backup
batteries. The backup batteries are charged during operation of the instrument, and can retain the
contents of memory for 10 months if they have been fully charged. At time of purchase, the batter-
ies may have already been partially discharged, so turn the power on to charge them. The batteries
can be fully charged about 20 hours.
• Do not replace the internal backup batteries (type: ML2020 3V yourself. Contact the nearest Minolta-
authorized service facility to replace the backup batteries.
• We recommend that you backup all important data and store it separately.

6
Notes on Storage
• The CR-400/410 should be stored at temperatures between -20 and 40 ˚C and a maximum relative
humidity of 85%. Do not store it in areas subject to high temperatures, high humidity, or rapid
changes of temperature, or where condensation may occur. For added safety, we recommend that it
is stored with a drying agent (such as silica gel at room temperature.
• Do not leave the CR-400/410 inside a car or in the trunk of a car. Under direct sunlight in summer,
the increase in temperature can be extreme and may result in malfunction.
• Do not store the CR-400/410 in areas where dust, cigarette smoke, or chemical gases are present.
Doing so may cause deterioration in performance or breakdown.
• When not using the white calibration plate, close the cover and store it.
• Do not throw away the packing materials (cardboard box, cushioning material, plastic bags, etc. .
They can be used to protect the instrument during transportation to a service facility for mainte-
nance (re-calibration etc. .
• If you are not going to be using the CR-400/410 for more than two weeks, the batteries must be
removed. If the batteries are left in the instrument, leakage may occur resulting in damage to the
instrument.
Notes on Cleaning
• If the CR-400/410 becomes dirty, wipe it with a soft, clean dry cloth. Never use solvents such as
thinner and benzene.
• If the white calibration plate becomes dirty, wipe it gently with a soft, clean dry cloth. If dirt is
difficult to remove, wipe it with lens cleaner and cloth, then dry.
• If the CR-400/410 break down, do not try to disassemble and repair it by yourself. Contact a Minolta-
authorized service facility.
