  • Page 49: Outline Of The Settings Section

    Available measurement methods and the settings that must be made are explained below. <Measurement by Minolta’s Calibration Standard> 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 ex- plained below.
  • Page 50 <Measurement by Analyzer Mode> 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.

  • Page 51: Before Making Each Setting

    (If xylv, T∆uvLv, u'v'Lv or XYZ mea- surement 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 emission characteristic for analyzer mode is stored in their common memory irrespective of measurement mode.

  • Page 54: User Calibration

    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 chan- nels. Once user calibration is performed, the following correction will be made when measurement is per- formed using the obtained correction factor.

  • Page 55: Performing White Calibration

    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.
  • Page 56 * 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 63). The currently set correction factor for white calibration will remain unchanged even if the target color is changed.

    3. Performing Matrix Calibration Matrix calibration cannot be performed with the memory channel CH00. (CH00 memory channel is provided for measurement that uses the Minolta’s calibration standard.) Matrix calibration must be performed for each display type (model).

  • Page 61: Analyzer Mode

    Analyzer Mode 1. About Analyzer Mode <What is 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).

  • Page 62: Inputting The Rgb Emission Characteristic For Analyzer Mode

    2. 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 white 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.

  • Page 103: Measuring Principle

    Measuring Principle 1. Measuring Principle This instrument uses sensors of a spectral sensitivity similar to the CIE 1931 color-matching function ( – – x λ, – yλ, – zλ) to measure RGB emission energy of a color display, and displays the results in xyLv, T, ∆uvLv, u’v’Lv, flicker or XYZ values.

  • Page 104: About T∆Uvlv

    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 black- body locus (∆uv), and the intensity is expressed in Lv.

    (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.

  • Page 106: Principle Of Analyzer Mode

    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 luminous intensity of each monochromatic light and displayed.
  • Page 107 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. y - λ z - λ λ Fig. 3 Outputs of Sensors – x λ, –...

  • Page 108: Maintenance

    If the instrument gets dirty, wipe it with a soft dry cloth. Never use solvents such as thinner and benzene. If the measuring probe receptor’s objective lens gets dirty, wipe it with a soft dry cloth or lens cleaning paper. Should the instrument break down, do not try to disassemble it by yourself. Contact a Minolta-authorized service facility.

    If any of the following symptoms occur with the instrument, take the corrective actions given in the table below. If the instrument still does not operate correctly even if the necessary corrective actions are taken, the instrument might have broken down. Contact a Minolta-authorized service facility. When doing so, please inform them of the breakdown No.
