Calibration
Calibration Channels
This instrument has calibration channels numbered from CH00 to CH10 (11 channels in total). CH00 is a channel for performing measurement in accordance with the Konica Minolta calibration standard. It is preset with correction coefficients for Konica Minolta calibration which cannot be changed by the user. Users can set the following item to each of CH01 through CH10.
1. User calibration correction coefficient The user calibration correction coefficients are used in common in one calibration channel for each measurement mode of Lv x y, Lv uv, Lv Tcp duv, X Y Z, and dominant wavelength.
64

Measurement CAL Preparation

User Calibration
User calibration allows users to set their own correction coefficients to the calibration channel of the instrument by specifying calibration values (Lv, x, y; Lv, u, v; or X, Y, Z) on the instrument. After setting, the value corrected with the specified correction coefficients will be displayed/output for every measurement. You can use user calibration to apply the following correction to measurement based on the specified correction coefficients.
1. Correct the difference in the reading due to the inconsistency between the CIE 1931 color matching functions and spectral sensitivity.
2. Correct the difference in the readings between the instruments used simultaneously. The user calibration offered by the instrument is a single- color calibration. To perform an RGB or RGB+W matrix calibration, you need to use the data management software CSS20. It ensures accurate measurement of luminance and chromaticity near the calibration light source. When you obtain the calibration value by measuring the calibration light source with a
measurement reference device, be sure to set the reference device and this instrument at the same position and angle from the calibration light source and measure the same measuring area. The instrument may not be calibrated properly if the measurement conditions are different from those of the reference device. During the measurement, use a constant-voltage power supply for illuminating the calibration light source to ensure conditions are as stable as possible.
User calibration can be performed for every calibration channel except for CH00. There are two methods to perform user calibration:
1. By measurement …………………..(page 66 and 67) 2. By selecting stored data………..(page 68 and 69) The procedures are described below.
You cannot perform user calibration for calibration channel CH00. (CH00 is a calibration channel for performing measurement in accordance with the Konica Minolta calibration standard.) The user calibration correction coefficients are used in common for each color space of Lv x y, Lv uv, Lv Tcp duv, X Y Z and dominant wavelength.

Explanation and Information

Light-Receiving Element (Sensor)

The CS-150/160 is a high-accuracy tristimulus luminance color meter using three sensor outputs (XYZ = Red, green and blue) of the spectral responsivity corresponding to human eye sensitivity (CIE1931 color matching function).
It uses this spectral responsivity to measure an object, calculates the obtained tristimulus values (X, Y and Z) to convert them into Lv x y, Lv uv, Lv Tcp duv, dominant wavelength, and excitation purity, and display the result as a measured value.
The chromaticity coordinates (x, y) using LV x y (CIE 1931 color space) can be obtained by the following equations:

Standard spectral luminous efficiency and spectral response of LS-150/160

The LS-150/160 is a high-accuracy luminance meter using a sensor output of the standard
spectral luminous efficiency corresponding to human eye sensitivity. JIS C 1609-1:2006 specifies the evaluation of the spectral responsivity of a luminance meter as follows based on the deviation “f1′” from the standard spectral luminous efficiency V () when the instrument is calibrated with a standard light source with spectral distribution of 2856K black body radiation.

The relative spectral responsivity of the LS-150/160 is equivalent to General Class AA (JIS C 1609-1:2006) and conforms to Class B of DIN 5032-7. The value f1′ is obtained by the following equation:

Lv Tcp duv Color Space

When this instrument is set to display the color mode Lv Tcp duv, the following values can be measured.
Lv : Luminance Tcp : Correlated color temperature duv : Color difference from black body locus
The Lv Tcp duv color mode expresses luminance with Lv and color with Tcp and duv.
< Relation between correlated color temperature Tcp and color difference from black body locus duv > Color temperature refers to the temperature of a black body (perfect radiator) which has equal chromaticity coordinates to a certain light. Consequently, color temperature can be used to represent colors only on black body locus. Correlated color temperature, slightly wider interpretation of color temperature, is very useful to eliminate this problem. Here, correlated color temperature covers colors which are slightly outside the range of black body locus. If a certain color is positioned on an isotemperature line, the intersection point of the isotemperature line and black body locus is indicated as the correlated color temperature for the color. An isotemperature line means a line on the chromaticity coordinate system which is a set of colors visually close to the color temperature on the black body locus. However, since all colors on one isotemperature line are represented with the same correlated color temperature, it is not possible to describe colors only with correlated color temperature. To solve the problem, duv, or deviation of correlated color temperature Tcp from the black body locus, is used. If duv exists above the black body locus, it is represented with “+”, and below, with “-“.

Dominant Wavelength/Excitation Purity

In the x, y chromaticity diagram shown below, the curve VScSR is the spectrum locus, and point N is the white point.
Colors located in the region enclosed by the spectrum locus and the straight lines VN and NR are referred to as spectral colors; and colors located in the triangle NVR with the white point N at the apex and the purple boundary VR as the base are referred to as non-spectral colors.

< Dominant wavelength and excitation purity (spectral colors) >
When the chromaticity point obtained by measurement is C, the wavelength corresponding to the intersection point S of the extension of NC with the spectrum locus (curve VScSR) is referred to as a dominant wavelength and is indicated by the symbol d. The ratio of the lengths of the straight lines NC and NS is referred to as the excitation
purity of color excitation C and indicated by the symbol pe.

< Complementary wavelength (non-spectral colors) >
When the chromaticity point obtained by measurement is C’, the extension of NC’ toward C’ does not intersect with the spectrum locus but with the purple boundary. In this case, the wavelength corresponding to the intersection point Sc of the extension of NC’ toward N with the spectrum locus is referred to as a complementary wavelength and is indicated by the
symbol c. This instrument also indicates it with the symbol d with a minus sign. When the intersection point of the extension of the line NC’ with the line VR (purple boundary) is designated by S’, the ratio of the lengths of NC’ to NS’ is referred to as excitation purity of color excitation C’ and is indicated by the symbol p’v.

The following equations are formulated where (xn , yn) is the chromaticity coordinates of point N, (xc , yc) is the chromaticity coordinates of point C, (x , y) is the chromaticity coordinates of point S, (xc’, yc’) is the chromaticity coordinates of point C’, and (xp, yp) is the chromaticity coordinates of point P:

Object Color Measurement

This implement is capable of simplified object color measurement through the use of the user calibration function.

Ensure that the white calibration plate (optional accessory) and the object to be measured are set in the same position and angle. If the illumination settings and measurement conditions are different between the white calibration plate and object to be measured, the measurement data is affected, resulting in incorrect measurement data.
During the measurement, use a constant-voltage power supply for the illumination light source to ensure conditions are as stable as possible.

Setup for Object Color Measurement
1. Prepare one or more illumination
light sources such as tungsten lamps, and set the white calibration plate as shown in the figure on the right.
Set up the instrument so that it faces the white calibration plate perpendicularly.
Set up the illumination light sources at a 45° angle.

The measured

value flashes.

6

The measured

value is displayed

as “——“.

Cause Is the value out of the guaranteed performance range? Is the measured value converted to large due to the user calibration? Does any data exist?
Is the color space set to color temperature?
Has a target been set for color difference measurement?

Action
The measured value flashes when it goes out of the guaranteed performance range.
The value flashes when the luminance exceeds the possible display range of the instrument.
This display indicates that there is no data for the measured value, stored data, calibration value, or target.
This display indicates that the instrument cannot convert color temperature to display a value. The possible display range is as follows:
1563 Tcp 99990 (K) |duv| < 0.1
This display is shown as the color difference when a target has not set.

repeatedly.

Cause Is the measured object stable?
Is the luminosity of the measured object significantly different from the previous measurement?
Is the USB cable connected securely? Is remote mode active?
Is the program correct?
Is the battery charge low because the instrument was used immediately after purchase or was not used for a long time?
Check the action for the error message.

Action
When the amount of light from the measured object is not stable, the instrument may stop measurement and try it again to ensure the optimum range. Measure the object while it is stable.
When the luminosity of the measured object differs greatly from the previous measurement, the instrument may stop measurement and try it again to ensure the optimum range.
Ensure secure connection between the instrument and PC.
Send the connect command from the PC to the instrument to set the instrument to remote mode. Use the data management software CS-S20.
Check the program by referring to the sample program. Or, use the data management software CS-S20.
Leave the power supply connected to charge the backup battery. The battery is fully charged in about 20 hours. The service life of the backup battery is about ten years of normal use. If, however, the memory is cleared quickly even after full charging, the battery must be replaced. For replacement, contact a KONICA MINOLTA-authorized service facility.
If the problem persists, contact a KONICA MINOLTAauthorized service facility.
