Explanation Section
Safety Precautions
When using this hardware, the following points must be strictly observed to ensure correct and safe use.
After you have read this manual, keep it in a safe place so that it can be referred to easily whenever it is needed.
Do not use the CA-Series in places where flam-
mable or combustible gases (gasoline etc.) are
present. Doing so may cause a fire.
Always use the AC power cord supplied as a stan-
dard accessory with the CA-Series, and connect it
to an AC outlet (100V-240V , 50-60 Hz). Fail-
ure to do so may damage the CA-Series, causing
a fire or electric shock.
Do not bend, twist or pull the AC power cord ex-
cessively. In addition, do not place heavy items
on the AC power cord, or damage or modify it in
any way. Doing so may cause damage to the AC
power cord, resulting in fire or electric shock.
If the CA-Series will not be used for a long time,
disconnect the AC power cord from the AC outlet.
Accumulated dirt or water on the prongs of the
AC power cord’s plug may cause a fire. If there is
any dirt or water on the prongs of the AC power
cord’s plug, remove it.
The CA-Series should not be operated if dirt or
dust has entered through the vent holes. Doing so
may result in a fire. For periodic inspection, con-
tact the nearest Minolta-authorized service facil-
ity.
WARNING (Failure to adhere to the following points may result in death or
serious injury.)
When disconnecting the AC power cord’s plug,
always hold the plug and pull it to remove it. Never
pull the AC power cord itself. Doing so may dam-
age the AC power cord, causing a fire or electric
shock. In addition, do not insert or disconnect the
AC power cord’s plug with wet hands. Doing so
may cause electric shock.
Do not disassemble or modify the CA-Series. Do-
ing so may cause a fire or electric shock.
Take special care not to allow liquid or metal ob-
jects to enter the CA-Series. Doing so may cause a
fire or electric shock. Should liquid or metal ob-
jects enter the CA-Series, turn the power OFF im-
mediately, disconnect the AC power cord from the
AC outlet, and contact the nearest Minolta-autho-
rized service facility.
The CA-Series should not be operated if it is dam-
aged, or smoke or odd smells are detected. Doing
so may result in a fire. In such situations, turn the
power OFF immediately, disconnect the AC power
cord from the AC outlet, and contact the nearest
Minolta-authorized service facility.
Take care not to drop or overturn the CA-Series.
Failure to adhere to this precaution may result in
injury or your body being trapped.
Do not place the instrument on an unstable or slop-
ing surface. Doing so may result in its dropping
or overturning, causing injury. Take care not to
drop the instrument when carrying it.
CAUTION (Failure to adhere to the following points may result in injury or
damage to the instrument or other property.)
Be sure to connect the AC power cord’s plug to an
AC outlet that has a protective grounding termi-
nal. Also make sure that peripheral devices (e.g.
PC) are connected to AC outlets that have a pro-
tective grounding terminal. Failure to do so may
result in electric shocks.

Foreword
Thank you for purchasing the Display Color Analyzer CA-210. This instrument is designed for measurement of
color, intensity and flicker of various types of color displays including color LCD displays. Before using this
instrument, please read this manual thoroughly.
Notes on Use
●This instrument is designed for indoor use only, and should not be used outdoors.
●The instrument must never be disassembled as it is composed of precision electric components.
●Always use the rated power voltage (100-240V ). Connect the AC power cord to an AC outlet (100-240V ,
50-60 Hz). Make sure that the voltage is within ±10% of the rated power voltage.
●The operating environment for this instrument should conform to “Pollution Degree 2” (i.e. where there is no
possibility of metal dust and condensation), “Installation Category II” (i.e. the specified commercial power
voltage should be used) and altitude of below 2000 m.
●The instrument must not be used if foreign matter such as water and metal objects enter it, doing so is very
dangerous.
●The instrument should not be used in certain environments, such as near a heater which will cause an excessive
rise in its temperature resulting in breakdown. Therefore it should not be used in such an environment. It should
be used in well-ventilated areas, and care should be taken not to allow the vent holes to become blocked.
●The instrument must not be used in areas subject to rapid changes of temperature, to avoid condensation.
●The instrument must not be used in areas where there is an excessive amount of dust or where the humidity is
excessively high.
●The instrument should be used at ambient temperatures of between 0 and 40˚C and humidity of 85%RH or less.
●The instrument must not be exposed to excessive impact and vibrations.
●The AC power cord must not be pulled or bent excessively nor must excessive force be exerted on it. Doing so
may result in wire breakage.
●The AC power cord must not be connected to an AC line on which excessive noise is present.
●The instrument and personal computer must be grounded.
●If any irregularity or abnormality is found, turn OFF the power immediately, disconnect the AC power cord, and
refer to “Breakdown check” on page 105.
●Should the instrument break down, do not try to disassemble by yourself. Contact a Minolta-authorized service
facility.
●The LCD screen may sometimes be difficult to see if the instrument is used at near 0˚C. In this case, wait for one
to two minutes after the power is turned ON, and check the LCD.
●If the intensity of the display to be measured is 0.1 cd/m2or less, perform zero calibration after an elapse of 30
minutes or more after the POWER switch is set to ON.
Notes on Storage
●The instrument should be stored at temperatures of between -20 and 55˚C (humidity of 85%RH or less at 35˚C/
no condensation). Do not store it in areas subject to high temperatures and high humidity. For added safety, it is
recommended that it be stored with a drying agent (such as silica gel) at near room temperature.
●Take care not to allow condensation to form on the instrument during storage. In addition, pay attention to rapid
temperature changes during transportation to the storage area to prevent condensation.

Explanation Section
Cleaning
●If the instrument gets dirty, wipe it with a soft dry cloth. Never use solvents (e.g. benzene, thinner) or other
chemicals.
●If the optics of the probe gets dirty, wipe it with a soft dry cloth or lens cleaning paper.
●If it not possible to remove dirt from the instrument, contact a Minolta-authorized service facility.

About Measuring Probe
Setting a Measuring Probe
Two types of screws are provided to secure the measuring prove.
Tripod screw: Used to mount the prove to a tripod. The screw depth is 6 mm.
ISO screw: Used to mount the prove to a jig. An ISO screw (5 mm, depth: 6 mm) can be used.

Setting the Measuring Distance
1. Secure the display to be measured.
2. Set the switching ring to the POINTER posi-
tion.
A circle marker will be emitted.
3. Check the area to be measured, make sure
that the distance from the display surface
to the tip of the probe is 30 mm, and se-
cure the probe.
Make sure that the probe is placed perpendicular to
the display surface.
JEITA ED-2522 states that measurement must be taken for an area of 500 pixels or more with the light receiving
angle of 5 degrees less. This requirement can be met if the object is placed as explained above since this instrument
is designed to measure ø27 mm at ±2.5 degrees. Use of the hood (standard accessory) not only prevents entry of
environmental light but also makes it easy to place the instrument at the specified distance and perpendicular to the
object.
•Measurement can be performed with stable accuracy if r= 30 mm±10 mm.
•The optimum angle varies with the display’s light distribution characteristic.

Installation/Connection
Switching ring
About Switching Ring
When you turn the switching ring, it stops at three positions (MEAS, 0-CAL, POINTER). To turn the ring, the
stopper must be pulled toward you to unlock it.
MEAS : To perform measurement, the ring must be set in this posi-
tion.
0-CAL : To perform zero calibration, the ring must be set in this
position.
Take care not to direct the measuring probe to a high-in-
tensity light source.
POINTER: A red circle marker will be emitted from the LED. It may
be difficult to see the marker depending on the surround-
ing brightness and intensity or color of the object. In this
case, place a piece of white paper over the screen.
You must also take care not to stair into the prove while
the marker is emitted.
