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/m

or 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 secure 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-intensity light source.

POINTER: A red circle marker will be emitted from the LED. It may

be difficult to see the marker depending on the surrounding 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.

Zero Calibration

Zero calibration performs zero point adjustment while blocking entry of light into the measuring probe’s receptor. Zero calibration must be performed whenever the POWER switch is set to ON.

1. Performing Zero Calibration

● If the intensity of the display to be measured is 0.1 cd/m

or less, perform zero calibration after elapse of 30 minutes or more after the POWER switch is set to ON. When measuring such a low-intensity display for a long period of time, perform zero calibration approximately every hour.

● Perform zero calibration if the ambient temperature has changed.

● Zero calibration can be performed anytime even if “PUSH 0-CAL KEY” is not displayed.

● Never direct the measuring probe toward the illuminant during zero calibration.

● Never press any keys during zero calibration. Doing so will cause completion of zero calibration to take more

time.

● When the optional 4-point expansion board CA-B14 is used

Zero calibration will be performed simultaneously with all the connected measuring probes.

[Operating Procedure]

Before starting zero calibration, check that a measuring probe is connected to the probe connector [P1] on the instrument.

1. Check that the POWER switch is set to ON.

2. Set the Switching ring to the 0-CAL position.

Be careful because zero calibration can't be done properly.

・Don't turn the tip of Probe to the high illuminant. ・Don't carry out zero calibration under the condition that the switching-ring is set in "POINTER".

When the optional 4-point expansion board CA-B14 is used

Set the switching ring of every measuring probe to the 0-CAL position. Zero calibration will not be performed correctly if the switching ring of any of the measuring probes is not set to the 0CAL position.

3. Press the 0-CAL key.

Measurement will start automatically at the end of zero calibration.

“E1” is always displayed if the instrument is used for the first time since shipment from the factory.

● “TOO BRIGHT” (During zero calibration)

• Cause : Light is entering the measuring probe’s recep-

tor.

• Action : Block the light completely, and when “PUSH 0-

CAL KEY” appears press the 0-CAL key again to start zero calibration.

● “E1” (After completion of zero calibration)

• Cause : “E1” is displayed if the instrument is used for

the first time since shipment from the factory, because no target color has been set.

• For other cases, refer to page 101.

2. Zero Calibration Check Method

If you want to check whether zero calibration has been performed correctly, block entry of light into the measuring probe’s receptor using a blackout curtain etc.

• If the message shown on the right appears in the LCD

display section, perform zero calibration again.

• Zero calibration has been completed correctly if “000”

blinks for “Lv” in the digital display section. If a value other than “000” is displayed, perform zero calibration again.

Outline of the Settings Section

This section explains settings that must be made according to measurement method. Available measurement methods and the settings that must be made are explained below.

With this method, measurement is performed using Minolta’s calibration standard without calibration. Even if you are setting the target color to the memory channel CH00, measurement must be performed as explained below.

It is not necessary to set/change the target color if you are not going to use the analog display function.

[Operating Procedure]

• To set an ID name : “Setting an ID Name” (Page 65) *2

• To use the analog display function : “Setting an Analog Display Range” (Page 67) *3

With this method, user calibration is performed and the obtained correction factor is used for measurement. Since the target color is also set, the analog display section can show the deviation of the measured values from the target color. User calibration must be performed in the following cases. (However, it is not possible to perform user calibration using the memory channel CH00.)

• To correct variation of readings that occur due to the deviation of spectral sensitivity from the CIE 1931 color-

matching function

• To correct difference of readings between instruments when two or more instruments are used

With this method, the measured colors are expressed in luminous intensity of each R, B and G monochromatic light based on the display’s analyzer mode RGB luminescence characteristic (which is input to the instrument’s memory channel) and the target color (W). Since the target color is also set, the analog display section can show the deviation of the measured values from the target color. If this method is used when adjusting display’s white balance, the adjustment can be performed more easily than xyLv mode.

1. About Memory Channels

This instrument has a total of 100 channels (CH00 to CH99). The following items can be set for each of these channels.

1 Correction factor for user calibration ...........................

.................................... (For details, refer to page 49.)

2 RGB luminescence characteristic for analyzer mode ......

.................................... (For details, refer to page 57.)

3 Target color .................... (For details, refer to page 47.)

4 ID name .......................... (For details, refer to page 65.)

CH00 is provided for calibration that uses Minolta’s calibration standard. For this channel, only the target color, RGB luminescence characteristic for display’s analyzer mode and ID name can be set. The desired memory channel can be selected by switching from one to another by pressing the MEMORY CH

and keys.

It is also possible to assign an ID name to each memory channel by entering it directly using keys. The ID name is displayed together with the memory channel no. in the LCD display section.

● If the RGB luminescence characteristic for analyzer mode is input using a memory channel that has been

matrix-calibrated, the correction factor for matrix calibration will be deleted. (If xylv, TÉ¢uvLv, u'v'Lv or XYZ measurement mode is selected, the Minolta’s calibration standard will be used for measurement.)

● In the case of the same memory channels and probes, the RGB luminescence characteristic for analyzer mode

is stored in their common memory irrespective of measurement mode. Therefore, when matrix calibration is performed, the RGB luminescence characteristic for analyzer mode is also input at the same time.

The correction factor for user calibration (1), RGB luminescence characteristic for analyzer mode (2) and target color (3) can be set for each probe. However, ID name (4) is common to all the probes of the same memory channels. For instance, if the ID name “CRT-001” is assigned to CH01 when the measured values for probe [P1] are displayed, “CRT-001” will be displayed for CH01 of all the probes [P1] to [P5].

2. About the Target Color

The target color is the reference used to measure how much the measured values are deviated from a certain color. The target color can be set for each probe of each memory channel. The target color is set when the following is performed.

1 User calibration (page 49) ....................... Performing user calibration sets the calibration values as the target

color.

2 Setting/changing the target color ............. Set or change the target color in the following cases.

(page 60) • When you want to set the target color for memory channel CH00

• When you want to set a color that differs from the color used for user

calibration as the target color to a user-calibrated memory channel

• When you want to perform measurement using Minolta’s calibra-

tion standard without user calibration and want to use the analog display function

3 Inputting the RGB luminescence ............ When you select analyzer measurement mode and input the RGB

characteristic for analyzer mode luminescence characteristic for analyzer mode, also set the target color (page 57) (W).

● Since when calibration factor is input for user calibration/analyzer mode the target color is also set at the same

time, the previously set target color will be deleted.

● To change the currently set target color, change it as explained in “Setting/Changing the Target Color” (page

60). Even if the target color is changed, the currently set correction factor for user calibration and the RGB luminescence characteristic for display’s analyzer mode will remain unchanged.

In the case of the same memory channels, the target color is stored in their common memory irrespective of measurement mode. As a result, the target color set last will be stored irrespective of how it was set.

Values that can be set to one memory channel

* The target color is common irrespective of color space mode.

User Calibration

1. About User Calibration

● User calibration is provided to set the user’s own correction factor to the instrument’s memory channels by

measuring the color of a display and setting the calibration values (x, y, Lv) to the instrument. Once this factor is set, the values corrected by this factor will be displayed and output each time measurement is taken.

● This instrument allows two kinds of user calibration; white calibration and matrix calibration.

By default (factory setting), matrix calibration is selected.

● User calibration can be performed for each memory channel. (Except for CH00)

● When the optional 4-point expansion board CA-B14 is used

User calibration is performed independently for probe connectors ([P1] to [P5]) for each memory channel. (Except for CH00)

● When this instrument is used for the first time since shipment from the factory, measurement will be performed

based on the calibration carried out by the Minolta’s calibration standard. This applies to all the memory channels. Once user calibration is performed, the following correction will be made when measurement is performed using the obtained correction factor. 1 Correction of variation of readings that occur due to the deviation of spectral sensitivity from the CIE 1931

color-matching function

2 Correction of difference of readings between instruments when two or more instruments are used

3 When the optional 4-point expansion board CA-B14 is used

Correction of difference of readings between measuring probes when two or more probes are used

● At the same time as user calibration is performed for a memory channel, the obtained color will be set as the

target color to that memory channel. The target color is the color used as the reference when displaying how much the measured values are deviated from a certain color. (Page 47)

When two or more instruments are used or when the optional 4-point expansion board CA-B14 is used to perform measurement with two or more measuring probes, the difference between readings can be corrected if user calibration is performed as explained below.

When the values of the color to be used as the target are known:

The color set to the reference display is displayed and user calibration is performed for all the bodies (or measuring probes).

When the values of the color to be used as the target are unknown:

1 Select one master body (or select one master probe). 2 Select “xyLV” measurement mode (page 38), and place the master body’s measuring probe (or the master

probe) against the display on which the target color is displayed.

While the probe is placed against the display, press the HOLD key.

4 By using the display on which the target color is displayed and the values displayed at step 3, perform user

calibration for the other bodies (or measuring probes).

2. Performing White Calibration

● User calibration cannot be performed with the memory channel CH00.

(CH00 memory channel is provided for measurement that uses the Minolta’s calibration standard.)

● White calibration must be performed for each display type (model).

Characters of displays vary with the display type (model). Because of this, measured values differ even if the same color is measured. Thus, a different memory channel must be used for each display type (model) to perform white calibration.

● If white calibration is performed with a memory channel to which the target color has already been set, that

target color will be deleted.

● If white calibration is performed with a memory channel which has already been matrix-calibrated, the correc-

tion factor of the previous matrix calibration will be deleted and the correction factor obtained from the white calibration will be set.

[Operating Procedure]

When the optional 4-point expansion board CA-B14 is used

Select the probe no. to be white-calibrated. White calibration can be performed independently for each probe connector ([P1] to [P5]) for each memory channel.

* To view the white-calibrated values (target color values), press

the MR key. However, if the target color is set after white calibration is performed with the same memory channel, the values for that target color will be displayed. (For details, refer to page

71.)

* If measurement is performed with non-user-calibrated memory

channel for the first time since shipment from the factory, the Minolta’s calibration standard will be used for the measurement.

* To change the target color you set, change it as explained in “1. Setting/Changing the Target Color by Measurement” (page 61). The

Analyzer Mode

1. About Analyzer Mode

Analyzer measurement mode is provided for adjustment of the display’s white balance. The measured colors are expressed in output of each R, B and G monochromatic light based on the display’s analyzer mode RGB luminescence characteristic (input to the instrument) and the target color (W). Thus, adjusting the luminous intensity of R causes the measured value of R only to change, and measured values for B and G remain unchanged This mode is useful when you adjust the luminous intensity of R, B and G to match the target color (W). The following measured values will be displayed when the display’s luminous intensity (luminous intensity of R, B and G monochrome lights) and the target color (W) are set and measurement is performed in analyzer mode.

• Digital display section ............................... R, B, G : Outputs of the currently measured monochrome lights R,

B and G in ratio (%) to those of the specified target color (W)

• Analog display section............................... When analyzer mode (G-reference) is selected

Inputting the RGB Luminescence Characteristic for Analyzer Mode

The RGB luminescence characteristic for analyzer mode must be input to each memory channel. When it is input, the target color (W) must also be set. To adjust white balance, the values of the white-balanced white must be entered as the white color (W). If the RGB luminescence characteristic for the display’s analyzer mode is input to a memory channel for which the target color has already been set, the previously set target color will be deleted. The target color to be used is the same as that for xyLv, T∆uvLv, u'v'Lv and XYZ measurement modes. The RGB luminescence characteristic for the display’s analyzer mode must be input for each display type (model). Characters of displays vary with the display type (model). Because of this, measured values differ even if the same color is measured. Thus, a different memory channel must be used for each display type (model) to input the RGB luminescence characteristic for analyzer mode.

Notes on When Inputting the RGB Luminescence Characteristic for Analyzer Mode

● By default (factory setting), the RGB luminescence characteristic for the display’s analyzer mode has not been

input. Thus, before performing measurement in analyzer mode, the RGB luminescence characteristic must be input.

● The target color is also set when the RGB luminescence characteristic is input. Note that the target color is common to all measurement modes (xyLv, T∆uvLv, analyzer, u'v'Lv, XYZ).

● If the intensity of the display to be measured is 0.1 cd/m

or less or if the ambient temperature has changed, zero

calibration must be performed before inputting the RGB luminescence characteristic.

● Static electricity on the display’s screen surface must be removed as much as possible.

● Make sure that the measuring probe is placed against the display. If it is tilted or moved, it is not possible to

input accurate luminescence characteristic.

● Take care not to let the measuring probe be exposed to excessive impact. In addition, do not pull or bend the cord excessively or exert excessive force on it. Failure to observe this may result in breakdown or wire-breakage.

●

keys may not be operable if “OVER” is displayed on the LCD display section.

● Never press the following keys during setting. Doing so will cancel setting of the luminescence characteristic and activate the mode corresponding to the pressed key. ( 0-CAL , MODE , MR , MEMORY CH , , )

● If the RGB luminescence characteristic for analyzer mode is input using a memory channel that has been matrix-calibrated, the correction factor for matrix calibration will be deleted. (Minolta’s calibration standard will be used for measurement if xyLv, T∆uvLv, u'v'Lv or XYZ measurement mode is selected.)

● In the case of the same memory channels and probes, the RGB luminescence characteristic for analyzer mode is stored in their common memory irrespective of measurement mode. Therefore, when matrix calibration is performed, the RGB luminescence characteristic for analyzer mode is also input at the same time.

Setting/Changing the Target Color

If you have input the RGB luminescence characteristic for user calibration/analyzer mode:

It is not necessary to set the target color in the following cases.

1 When you want to set the user-calibrated color as the target color for a memory channel 2 When you want to set the target color (W) which was set when the RGB luminescence characteristic for the

display’s analyzer mode was set as the target color

The target color set here is the same as those set by 1 and 2. Only when you want to change the currently set target color, should it be changed it as explained below.

By setting the target color, the difference between the measured value and the target color can be displayed in the analog display section. The target color can be set for each probe of each memory channel. The target color must be set in the following cases.

• When you want to set the target color for memory channel CH00

• When you want to perform measurement using Minolta’s calibration standard without user calibration and

want to use the analog display function

• When you want to set a color that differs from the color used for user calibration as the target color to a user-

calibrated memory channel

• When the optional 4-point expansion board CA-B14 is used

When you want to set the target color (W) that has already been set and another color as the target color to a memory channel for which the RGB luminescence characteristic for analyzer mode has been input

There are the following two methods of setting/changing the target color. Some memory channels do not allow you to set the target color.

1. Setting/changing the target ...................... The display’s measured value is set as the target color.

2. Setting the Analog Display Range

The analog display section displays the difference (%) between the measured value and the target color as well as the difference (%) between measured values in the case of a measurement mode other than flicker mode. In the case of flicker mode, the measured values will be displayed as they are. The range for each dot can be set as follows.

1 xyLv, T∆uvLv, u'v'Lv or XYZ measurement mode ..... ∆x, ∆y and ∆Lv

2 Analyzer Mode

For G-reference .............. R/G, B/G and ∆G

For R-reference............... ∆R, B/R and G/R

3 Flicker mode ................................................................ Flicker

The range must be set independently of 1, 2 and 3. In the case of 1, the range set here will be used commonly by all the modes. Thus, for instance, if ∆x and ∆y are set to 2% and ∆Lv is set to 10% for xyLv mode, ∆x and ∆y will be displayed in 2% and ∆Lv in 10% irrespective of the measurement mode (xyLv, T∆uvLv, u'v'Lv or XYZ). In the case of 2, the value set for G (G-reference), the value set for R (R-reference), the values set for R/G and B/G (G-reference) and those set for B/R and G/R (R-reference) will be common. Thus, for instance, if ∆G is set to 5% and both R/G and B/G are set to 3% in the case of G-reference, ∆R will be displayed in 5% and both B/R and G/R in 3% in the case of R-reference. In the case of 3, the analog display range for each dot can be set for flicker.

Settings Checking Method

1. Checking the Set Values

By pressing the MR key for less than two seconds in xyLv, T∆uvLv, u'v'Lv or XYZ mode, the values of the target color for the currently selected memory channel is displayed in the LCD display section as shown on the right.

When the optional 4-point expansion board CA-B14 is used

The values of the target color for the currently selected memory channel probe no. will be displayed.

● When white calibration is performed as user calibration

1 If only user calibration has been performed, the calibration values can be checked by checking the target

values. Since when user calibration is performed the color at the time of user calibration will be set as the target color automatically, the target color values match the calibration values. However, if a different color is set as the target color after user calibration, it is not possible to check the calibration values with this method.

2 It is possible to check the calibration value for W by performing steps 5 and 6 (

key→ key) of the

white calibration operating procedure (page 51). The value that appears first when the

key is pressed is the calibration value that was entered when the previous user calibration was performed. The values for the target color will be displayed if user calibration has not been performed.

● When matrix calibration is performed as user calibration 1 If only user calibration has been performed, the W calibration values can be checked by checking the

target values. Since when user calibration is performed the color at the time of W calibration will be set as the target color automatically, the target color values match the W calibration values. However, if a different color is set as the target color after user calibration, it is not possible to check the calibration values with this method.

Measurement

Before starting measurement, perform the following.

1. Performing Measurement

[Measuring Method]

1. Press the MEMORY CH and keys. keys to select

the memory channel for which user calibration has been performed (page 49), the RGB luminescence characteristic for analyzer mode that has been input (page 57) and the target color that has been set/changed (page 60).

2. Place the measuring probe against the display and per-

form measurement.

The measurement results will be displayed in the digital and analog display sections in the selected measurement mode.

● The digital and analog display sections are blinking.

• The measured Lv (intensity) is below 0.1 cd/m

for white calibration with Minolta’s calibration standard

or equivalent.

● Since the intensity of the display will be unstable for a while immediately after the display is turned ON, the

measured values must be read after they have stabilized.

● Static electricity on the display’s screen surface must be removed as much as possible.

● Perform zero calibration if the ambient temperature has changed.

● When measuring a display of intensity of 0.1cd/m

or less for a long period of time, perform zero calibration

approximately every hour.

● Make sure that the measuring probe is placed straight against the display. If it is tilted or moved, accurate

measurement cannot be performed.

● Take care not to let the measuring probe be exposed to excessive impact. In addition, do not pull or bend the

cord excessively or exert excessive force on it. Failure to observe these cautions may result in breakdown or wire-breakage.

Measurement Section

<Error Messages in LCD Display Section>......... For other error messages, refer to page 101.

● “OVER”

• Measurement is not possible since the instrument’s measurement range

is exceeded by the measured value. In the case of analyzer mode, the instrument’s measurement range or display range (100,000%) is exceeded by the measured value.

● “E1”

• Cause : In the case of xyLv, T∆uvLv, u'v'Lv or XYZ measurement mode,

the currently used measuring probe is different from the one used to perform user calibration and set the target color. In the case of analyzer mode, the currently used measuring probe is different from the one used to input RGB luminescence characteristic for analyzer mode and set the target color (W).

• Action: Use the same probe as the one used to input the RGB lumines-

cence characteristic and set the target color. Alternatively, input the RGB luminescence characteristic and set the target color using the currently used measuring probe.

● “E2”

• Cause : An error has occurred due to shift of the zero point because the

ambient temperature has changed since zero calibration.

• Action: Perform zero calibration.

* Measurement can still be performed even if “E2” is currently displayed. * “E2” will not appear if “E1” is currently displayed.

When the optional 4-point expansion board CA-B14 is used

● If two or more measuring probes are connected, measurement will be performed with all the probes simulta-

Measurement Section

White Balance Adjustment in Analyzer Mode

Analyzer measurement mode is provided for adjustment of the display’s white balance. The measured colors are expressed in luminous intensity of each R, B and G monochromatic light based on the RGB luminescence characteristic for analyzer mode (page 57) and the target color (W) which are set to the instrument. Thus, adjusting the luminous intensity of R causes the measured value of R only to change, and measured values for B and G remain unchanged. This mode is useful when you adjust the luminous intensity of R, B and G to match the target color (W).

First, set the RGB luminescence characteristic for analyzer mode and target color (W) to the instrument. For the target color (W), the values of the white-balanced white must be entered. (Page 57)

If “100” is displayed for R, B and G in the digital display section when measurement is performed in analyzer mode, this indicates that the color of the display measured is the same as the target color (W) (i.e. the xyLv values are the same) for the selected memory channel. In the analog display section, only the center green segments light up.

When only the center green segments light up in the analog display section and all the values for R, B and G in the digital display section are the same (but not “100”), this indicates that the chromaticity coordinates (x, y) are the same as those of the target color (W), though Lv (intensity) differs. Even if the intensity of the display changes, the chromaticity coordinates (x, y) are the same as those of the target color (W) as long as the values for R, B and G are the same. In this case, in the analog display section, only the center green segments for R/G and B/G (G reference) or G/R and B/R (R reference) light up.

G-reference or R-reference must be chosen according to the display whose white balance is to be adjusted.

• G-reference: Must be used for displays whose G output cannot be adjusted independently.

• R-reference: Must be used for displays whose R output cannot be adjusted independently.

* Any of G-reference and R-reference can be used for displays whose R, G and B outputs can be adjusted independently.

7. Adjust the white balance.

Normally, white balance can be adjusted by performing cutoff and drive adjustment for the display. In this section, the method of adjusting the display’s color to the target color (W) is explained.

The method is explained by taking the following cases where the measured values are as follows compared to the target color (W).

• luminous intensity of R: Higher by 20%

• luminous intensity of B: Lower by 10%

• luminous intensity of G: Higher by 10%

7-1. When analyzer mode (G-reference) is se-

lected

1 Adjust the intensity (or luminous intensity of G)

so that the displayed value for G changes from “110” to “100.0”.

2 Adjust the output of R so that the displayed value

for R changes from “109.0” to “100.0”, and adjust the output of B so that the displayed value for B changes from “81.80” to “100.0”.

When all the values for R, B and G are changed to “100.0”, adjustment of the white color of the display to the target color (W) (i.e. the xyLv values are the same) is complete.

7-2. When analyzer mode (R-reference) is selected

1 Adjust the intensity (or luminous intensity of R)

so that the displayed value for R changes from “120.0” to “100.0”.

2 Adjust the output of B so that the displayed value

for B changes from “75.00” to “100.0”, and adjust the output of G so that the displayed value for G changes from “91.70” to “100.0”.

When all the values for R, B and G are changed to “100.0”, adjustment of the white color of the display to the target color (W) (i.e. the xyLv values are the same) is complete.

* The RGB values given in the above example are based on calculations, and may not correspond to the actual display.

Selecting the Measurement Speed

Select the measurement speed according to your application. If the measurement speed is changed, display frequency of the measurement results will change accordingly. The measurement results are displayed at the following frequency.

FAST mode

Requires short measurement time, but measurement accuracy is not sufficient in the case of measurement of a lowintensity display.

SLOW mode

Repeats measurement in FAST mode five times, and displays the average of the five measured values. This mode is used when you want to perform accurate measurement.

AUTO mode

Switches measurement speed to FAST or SLOW automatically according to the intensity of the display measures. Normally, this measurement speed is recommended. The measurement speed switches from FAST to SLOW or vice versa at the following intensity.

FAST → SLOW: When Lv drops below 2.0 cd/m

SLOW → FAST: When Lv exceeds 3.0 cd/m

* In the case of flicker mode, FAST measurement speed is always selected irrespective of the measurement speed setting.

When the optional 4-point expansion board CA-B14 is used

FAST → SLOW: When Lv for any of probes drops below 2.0 cd/m

SLOW → FAST: When Lv for all the probes exceed 3.0 cd/m

Measuring Principle

1. Measuring Principle

This instrument uses sensors of a spectral sensitivity similar to the CIE 1931 color-matching function (

––

x2λ, –yλ, –zλ)

to measure RGB luminescence energy of a color display, and displays the results in xyLv, T, ∆uvLv, u’v’Lv, flicker or XYZ values. Measurement is performed in the following sequence.

1 RGB luminescence energy of the color display is acquired through the measuring probe’s receptor, and

then converted to a voltage by the photoelectric conversion section. (Outputs: X

2, Y, Z)

2 The temperature of the probe is detected by the temperature detection section. (Output: T) 3 The outputs (X

2, Y and Z of 1) from the photoelectric conversion section and the output (T of 2) from the

temperature detection section are digitized in the A/D conversion section. A/D conversion is performed simultaneously within the measurement time according to SYNC mode.

4 The digitized values (counts) are sent to the instrument’s CPU, where they are calculated according to the

measurement mode, SYNC mode and correction factor (user calibration), which have been set using keys and switches.

5 The processing results are then displayed in the display sections, and output to a PC via RS-232C or USB.

Chromaticity coordinates (x, y) for Yxy (CIE 1931 color space) are obtained by the following formula.

X, Y and Z in the formula are tristimulus values (X = X

+ X2 = 0.16727Z + X2).

2. About T∆uvLv

If the instrument’s measurement mode is set to T∆uvLv, the following values can be displayed in the digital display section.

• T : Correlated color temperature

•∆uv : Color difference from the blackbody locus

• Lv : Intensity

In T∆uvLv mode, colors are expressed in the correlated color temperature (T) and color difference from the blackbody locus (∆uv), and the intensity is expressed in Lv.

About Correlated Color T emperatur e T and Color Difference fr om Blackbody Locus ∆uv

The temperature of a blackbody (full radiator) that has the same chromaticity coordinates as that of a light is called the color temperature of that light. However, only the colors that are present along the blackbody locus can be expressed in color temperatures. Thus, with a widened concept of color temperature, correlated color temperatures are used to express colors that are slightly off the blackbody locus. When a color is on the isotemperature line, the color temperature at the point where that line crosses the blackbody locus is assumed to be the correlated color temperature of that color. The isotemperature line is the line that is drawn along the chromaticity coordinates of a collection of colors that you feel visually similar to color temperatures along the blackbody locus. However, since all the colors on the same isotemperature line are expressed by the same correlated color temperature, it is not possible to express colors using correlated color temperatures only. Thus, to express colors, ∆uv, that indicates positional relationship with the correlated color temperature T, is also used. ∆uv is signed with “+” if the color is located above the blackbody locus, and is signed with “–” if it is below the blackbody locus.

3. Principle of User Calibration

This instrument uses three detectors provided in the measuring probe’s receptor to measure the colors of the display. The spectral sensitivity of these detectors does not match that of CIE 1931 color-matching function perfectly. Because of this, some colors of the display are affected by slightly shifted spectral sensitivity, resulting in the situation that absolute values of the measured values differ from the values (true values) obtained when the CIE 1931 color-matching function is used. This instrument allows one of the user calibration methods; white calibration (single-color calibration) or matrix calibration (RGB+W calibration). By performing user calibration, the influences that occur due to slight differences between the spectral sensitivity of the detectors used in the instrument and that of CIE 1931 color-matching function can be corrected when measurement is performed. These user calibration methods have the following features, so the user calibration that best suits your application must be selected.

White Calibration

User’s own correction factor is set to the memory channels by measuring the white color of known values and setting the obtained calibration values (xyLv) to the instrument. Once this factor is set, the measured values will be displayed after correction by this factor and output each time measurement is taken. Performing user calibration provides higher accuracy for measurement of colors that are close to the white color.

Matrix Calibration

User’s own matrix correction factor is set to the memory channels by measuring three monochrome colors (R, G and B) of known values and setting the obtained calibration values (xyLv) and luminescence characteristic to the instrument. Once this factor is set, the measured values will be displayed after correction by this factor and output each time measurement is taken. Performing matrix calibration enables high-accuracy measurements of LCD displays that provide colors through additive color mixing of three monochrome colors (R, G and B). Since the matrix correction factor obtained from Minolta’s calibration standard has been set, measured values calculated based on this factor will be acquired when this instrument is used for the first time since shipment from the factory.

Correction of Reading Differences between Instruments using User Calibration

(When two or more instruments are used or when the optional 4-point expansion board CA-B14 is used to use two or more measuring probes) Some measuring probes may have a slightly different spectral sensitivity. As a result, even if you are measuring the same display, measured values may differ from one instrument to another (difference of readings between instruments). Such influences can be corrected by performing user calibration using the same display and the same calibration values.

Explanation Section

4. Optical System of CA-210 Probe

The optical system consists of an objective lens and optical fiber. Among the lights emitted from the LCD under measurement, only the lights that are emitted at within ±2.5 degrees perpendicular to the LCD are guided by the objective lens to the fiber. After being input to the fiber, the lights are divided into three portions, and each portion is received by a sensor that has a spectral sensitivity similar to the CIE 1931 color-matching function. (Three sensors in total).

EIAJ ED-2522 stipulates the following measuring requirements for LCD evaluation methods.

• Light receiving angle must be within 5 degrees.

• The measuring area must consist of 500 pixels or more.

This instrument satisfies the above requirements since it employs an optical system that receives only the lights emitted within ±2.5 degrees from a relatively wide measuring area (φ27).

5. Principle of Analyzer Mode

In analyzer mode, the luminescence characteristics of the display’s three monochrome lights (R, G, B) and the target color are set to the instrument’s memory. Once they are set, display’s screen colors obtained by measurement can be converted to luminous intensity of each monochromatic light and displayed. For instance, if the luminous intensity of R among R, G and B is adjusted, only the output of R will change and the outputs of B and G will remain the same, making white balance adjustment easy (white balance measurement is performed by adjusting the output of a monochrome color).

By setting the luminescence characteristics of the display’s three monochrome lights (R, G, B) and the target color to the instrument’s memory, the display’s screen colors can be displayed in values that correspond to the outputs of those monochrome colors. Since the outputs of the monochrome colors change according to the screen voltage and drive voltage for R, G and B, respectively, use of analyzer mode facilitates adjustment of display’s white balance.

Each sensor (spectral sensitivity: ––x

λ, –yλ, –zλ) of the measuring probe has sensitivity towards the display’s R, G and

B. Thus, even if R monochrome light is emitted on the display’s screen, an output will be provided from each sensor (–x

λ, –yλ, –zλ). This is also true in the case of G and B monochrome colors.

Therefore, to measure each of R, G and B monochrome colors independently, a certain technique is required. In this instrument’s analyzer mode, measurement is performed based on the following concept.

Fig. 1 shows measuring probe sensor’s spectral sensitivity and display’s R, G and B spectral distributions.

The outputs of sensors ––x

the hatched areas X

output of the monochrome color R, the output ratio will be constant because of the spectral characteristic of the display and sensors.

Explanation Section

The above also applies when only monochrome light G is emitted as well as when only monochrome light B is emitted, and the outputs are shown in Figs. 3 and 4, respectively.

By emitting each monochrome light alone and setting the output ratio of each sensor as a constant (correction factor) to the memory, the output of each monochrome light (R, G, B) can be calculated based on the output of each sensor, even when three colors are emitted by the display at the same time. R, G and B are displayed in percentage (%) to each monochrome light of the target color (W), being 100.

Therefore, before performing measurement in analyzer mode, the display’s luminescence characteristic and target color (W) must always be set to the instrument’s memory. In addition, for measurement in analyzer mode, the memory channel to which the same luminescence characteristic and target color (W) as those for the display to be measured were set must be used.

6. Principle of Flicker Mode

What is Flicker?

“Blinking“ that appears on the display under certain conditions is called flicker. This symptom occurs when settings like refresh rate and resolution do not match those set on the display, and in the case of LCD, it may also occur depending on the displayed colors. Since flicker occurs periodically, it has an adverse effect on the user’s eyes. The relationship between the time axis (horizontal) and intensity level (vertical axis) is shown in Fig. 1. From this, it is obvious that the intensity level changes periodically and the larger its amplitude the more clearly the flicker is recognized. In addition, it is known that the frequency of intensity level change is twice as large as that of the display’s vertical synchronizing signal.

Flicker Measurement Method

Two kinds of quantifying measurement methods are available: contrast method and JEITA method. With the CA-210 alone, the contrast method is possible. Use of the software supplied with the instrument also allows JEITA method. This section gives an outline of both quantifying measurement methods.

(1)Contrast Method

If the intensity level of the display changes as Fig. 1, it is considered that AC component (b) overlaps on the DC component (a). With the contrast method, the ratio of AC component to DC component is defined as the flicker amount. AC component (a) is defined as Vmax – Vmin and DC component (b) as (Vmax + Vmin)/2, and the flicker amount is calculated by the following formula.

Flicker amount = AC component / DC component

= (Vmax – Vmin)/{(Vmax + Vmin)/2} ×100 [%]

Fig. 1

Explanation Section

(2)JEITA Method

With the JEITA method, the amount of flicker does not depend on its frequency, and is calculated based on the AC and DC components of the measured intensity. However, human sensitivity to flickering starts to drop gradually at about 30 Hz, and when the frequency exceeds 60 Hz, it is no longer possible for humans to sense it.

From this, it is possible that even if a flicker of a large amplitude and frequency of 60 Hz or higher exists the human eye cannot recognize it as a flicker. Thus, with the JEITA method of flicker measurement, it is very important to know the exact amplitude and frequency of flicker energy, in addition to the AC /DC component ratio, that is defined by the contrast method. With the JEITA method, the measuring devices shown below are required for measurement.

Fig. 3 shows that the output signal (Fig. 1) from the luminance meter (used to measure the LCD) is guided to the integrator. To reconstruct what is seen by the human eye, the integrator sends the signal through a filter that decreases the sensitivity because of frequency difference, and then outputs it to the FFT analyzer. The signal is processed by the FFT analyzer (Fast Fourier Transform Analyzer), and is displayed in a form of energy distribution of frequency components (Fig. 4).

As shown in Fig. 4, when two or more frequency components (P0, Px1, Px2) exist, the maximum value among all the frequency components (Px1, Px2 in the case of Fig. 4) except for P0, that is the component of frequency 0, will be set as Px. With the JEITA method, the flicker amount in this example is calculated by the following formula.

Flicker amount = 10 × log (Px/P0) [dB]
