WARNING

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

standard accessory (for 100-120V or for 200-

240V ) with the CA-Series, and connect it to

an AC outlet . Failure to do so may damage the

CA-Series, causing a fire or electric shock.

Securely insert the power plug as far as it will go.

If the plug is not fully inserted, fire or electric

shock may result.

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 out-

let. 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 Konica Minolta authorized service

facility.

(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 Konica Minolta

authorized 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

Konica Minolta authorized service facility.

Take care not to drop or overturn the CA-Series.

About Installation

The operating environmental requirements are given in the “Specifications” of this manual. The instrument must be installed in a place that completely meets these requirements. (Page 110-113)

● Using the instrument in direct sunshine in midsummer or near a heater will cause a rapid rise in its temperature

resulting in breakdown. Special care must be taken when handling the instrument in such an environment. In addition, take care not to allow the vents to become blocked. Do not use the instrument in poorly ventilated areas.

● Do not use the instrument in a place where the temperature changes rapidly, since measured values will be

incorrect.

● 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 must not be used if foreign matter such as water and metal objects enter it, doing so is very

dangerous.

● 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.

● If any irregularity or abnormality is found, turn OFF(●●) the power immediately, disconnect the AC power

cord, and refer to “Troubleshooting Guide” on page 107.

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 luminance of the display to be measured is 1.0 cd/m2 or less (if LED Universal Measuring ø10 Probe(CA-

PSU32/35) or LED Flicker Measuring ø10 Probe(CA-PS32/35), 3.0 cd/m after elapse of 30 minutes or more after the POWER switch is set to ON. When measuring such a low-luminance 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 with illuminance exceeding the measurement range

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-Probe Expansion Board CA-B15 is used

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

or less), perform zero calibration

[Operating Procedure]

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



Pinting ring

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

2. Set the pointing 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 with illuminance exceeding the measurment range.

When the optional 4-Probe Expansion Board CA-B15 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.

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.

Selecting, Measurement Speed, SYNC Mode, Display Mode and the Number of Display Digits

1. 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 several times and displays the average. This mode is used when you want to perform accurate measurement.

AUTO mode

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

(LED Universal Measuring ø27 Probe) FAST → SLOW :When Lv drops below 4.0cd/m (CA-PU32/35) SLOW → FAST :When Lv exceeds 6.0cd/m

(LED Universal Measuring ø10 Probe) FAST → SLOW :When Lv drops below 12.0cd/m (CA-PSU32/35) SLOW → FAST : When Lv exceeds 18.0cd/m

(LED Flicker Measuring ø27 Probe) FAST → SLOW : When Lv drops below 2.0cd/m (CA-P32/35) SLOW → FAST : When Lv exceeds 3.0cd/m

(LED Flicker Measuring ø10 Probe) FAST → SLOW : When Lv drops below 6.0cd/m (CA-PS32/35) SLOW → FAST : When Lv exceeds 9.0cd/m

(In the case of Flicker Mode**, the measurement speed is always FAST mode.)

When the optional 4-Probe Expansion Board CA-B15 is used

(LED Universal Measuring ø27 Probe) FAST → SLOW : When Lv for any of probes drops below 4.0 cd/m2. (CA-PU32/35) SLOW → FAST : When Lv for all the probes exceed 6.0 cd/m

With this method, the measured colors are expressed in emission intensity of each R, B and G monochromatic light based on the display’s analyzer mode RGB emission 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.

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 emission 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, T∆uvLv, u'v'Lv or XYZ measurement mode is selected, the Konica Minolta’s calibration standard will be used for measurement.)

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

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

If the 4-Probe Expansion Board is installed, each probe ([P1] to [P5]) has a total of 100 channels (CH00 to CH99). The correction factor for user calibration (1), RGB emission 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 51) ......................... 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 62) • 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 Konica Minolta’s

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

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

characteristic for analyzer mode emission characteristic for analyzer mode, also set the target color (page 59) (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

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

Settings Section

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. In one memory channel and one probe, a correction factor of User Calibration is common to xyLv mode, T∆uvLv mode, u'v'Lv mode and XYZ mode. Target color is common to all measuring modes.

3. Selecting the Calibration Standard (data)

This section explains how to select the instrument’s calibration standard (6500K, 9300K). Selecting the instrument’s calibration standard will set the calibration standard for CH00 as well as for all the memory channels which have not been user-calibrated.

[Selecting Method]

1. Press the key.

The LCD display section will switch to the menu selection screen.

2. Press the key to open the

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-Probe Expansion Board CA-B15 is used

User calibration is performed independently for probe ([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 Konica 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-Probe Expansion Board CA-B15 is used

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

Settings Section

● 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 49)

● When User Calibration is implemented, the same Measuring Probe to be used for the measurement is necessary.

If measurement is carried out by connecting the different Measuring Probe, error message E1 will be displayed. In this case, it is necessary to replace it with the Measuring Probe that received User Calibration or you have to execute User Calibration once again using the Measuring Probe to be used for the measurement.

When two or more instruments are used or when the optional 4-Probe Expansion Board CA-B15 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 40), 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).

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

(CH00 memory channel is provided for measurement that uses the Konica 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.

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 emission characteristic (input to the instrument) and the target color (W). Thus, adjusting the emission 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 emission intensity of R, B and G to match the target color (W). The following measured values will be displayed when the display’s emission intensity (emission intensity of R, B and G monochrome lights) and the target color (W) are set and measurement is performed in analyzer mode.

Inputting the RGB Emission Characteristic for Analyzer Mode

The RGB emission 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 terget color (W). If the RGB emission 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 emission characteristic for the display 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 emission characteristic for analyzer mode.

key.

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

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

● The target color is also set when the RGB emission 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 1.0 cd/m

or less (3.0 cd/m2 or less when a LED Universal Measuring ø10 Probe(CA-PSU32/35) or LED Flicker Measuring ø10 Probe(CA-PS32/35) is connected.) or if the ambient temperature has changed, zero calibration must be performed before inputting the RGB emission 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 emission 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 emission characteristic and activate the mode corresponding to the pressed key. ( 0-CAL , MODE , MR , MEMORY CH , , )

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

calibrated, the correction factor for matrix calibration will be deleted. (Konica 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 emission characteristic for analyzer mode is

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

Setting/Changing the Target Color

If you have input the RGB emission 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 emission 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 Konica 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-Probe Expansion Board CA-B15 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 emission 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.

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 value

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 value.

● 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.

● When measurement is implemented, the same Measuring Probe to be used for the User Calibration is necessary.

● For measurement of flicker(only when LED Flicker Measuring ø27 Probe(CA-P32/35) or LED Flicker Mea-

suring ø10 Probe(CA-PS32/35) is connected.), make sure that the correct vertical synchronizing frequency is recognized by the instrument. If an incorrect vertical synchronizing frequency is set in the INT mode or instru-

ment is used in the UNIV mode, correct measured values will not be obtained in flicker measurement.

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 emission intensity of each R, B and G monochromatic light based on the RGB emission characteristic for analyzer mode (page 59) and the target color (W) which are set to the instrument. Thus, adjusting the emission 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 emission intensity of R, B and G to match the target color (W).

First, set the RGB emission characteristic for analyzer mode and the target color (W) to the instrument. For the target color (W), the values of the white-balanced white must be entered. (Page 59)

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 each display of R, B, G of the digital display part are a same value except for 100, that means the chromaticity coordinate is same as the standard color (W) although Lv (Luminance) is different. 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.

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

• G-Standard: Must be used for displays whose G output cannot be adjusted

independently.

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

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

7. Adjust the white balance.

Normally, white balance is adjusted by adjusting the cutoff and drive voltages. However, in the procedure below, the display is adjusted so that the white generated on the display matches the target color (W) stored in memory.

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

• emission intensity of R: Higher by 20%

• emission intensity of B: Lower by 10%

• emission intensity of G: Higher by 10%

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

lected

1 Adjust the luminance (or emission intensity of G)

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

The other value (R and B) may change somewhat if the intensity is adjust.

2 Adjust the out put of R so that the displayed value

for R changes from “109.0” to “100.0”, and adjust the out put 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-standard) is se-

Measuring Principle

1. Measuring Principle

This instrument uses sensors of a spectral sensitivity similar to the CIE 1931 color-matching function (––xλ, –yλ, –zλ) to measure RGB emission energy of a color display, and displays the results in xyLv, T∆uvLv, u’v’Lv or XYZ values. Measurement is performed in the following sequence.

1 RGB emission 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, Y, Z)

2 The temperature of the probe is detected by the temperature detection section. (Output: T) 3 The outputs (X, 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 xyLv (CIE 1931 color space) are obtained by the following formula.

X, Y and Z in the formula are tristimulus values

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 : Luminance

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

About Correlated Color Temperature T and Color Difference from Blackbody Locus

The temperature of a blackbody (an ideal 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. 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. (When two or more instruments are used or when the optional 4-Probe Expansion Board CA-B15 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. This instrument allows one of the user calibration methods; white calibration (single-color calibration) or matrix calibration (RGB+W calibration). 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 emission 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 displays that provide colors through additive color mixing of three monochrome colors (R, G and B). Since the matrix correction factor obtained from Konica 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.

Page 95

4. Principle of Analyzer Mode

In analyzer mode, the emission 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 emission of each monochromatic light and displayed. For instance, if emission 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).

Each sensor (spectral sensitivity: ––xλ, –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 (–xλ, –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 ––xλ, –yλ, and ––zλ when only the monochrome light R is emitted are the values equivalent to the hatched areas X

, YR and ZR, respectively. Although the outputs of these sensors change according to the output of the monochrome color R, the output ratio will be constant because of the spectral characteristic of the display and sensors.

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 emission 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 emission characteristic and target color (W) as those for the display to be measured were set must be used.

5. Optical System of Measuring 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 (LED Universal Measuring ø10 Probe(CA-PSU32/35) and LED Flicker Measuring ø10 Probe(CA-PS32/35) : ±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).

Optical fiber Sensor

Objective lens

IEC 61747-6 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.

Measuring probe 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). (LED Universal Measuring ø10 Probe(CA-PSU32/35) and LED Flicker Measuring ø10 Probe(CA-PS32/35), within ±5 degrees from a small measuring area(φ10).)

6. Principle of Flicker Mode

“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.

Two kinds of quantifying measurement methods are available: contrast method and JEITA method. With the CA-310 with LED Flicker Measuring ø27 Probe(CA-P32/35) or LED Flicker Measuring ø10 Probe(CA-PS32/

35) 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

Fig. 1

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 [%]

Page 99

(2) JEITA Method

With the contrast method, the amount of flicker does not depend on its frequency, and is calculated based on the AC and DC components of the measured luminance. 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.

Frequency HzFig. 2

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.

Integrator

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).

Page 100

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]
