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.

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:
x
=

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.

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.
