    Conventions <Illustrations for Operating Procedures> The section within this manual. Numbered order for operating pro- cedure. Key panel used for operation and po- sition of instrument. Screen display. Differs according to user settings. The Measuring Head has the and the data processor has the key.

  • Page 6: Notes On Use

    • The CR-400/410 may cause interference if used near a television, radio, etc. • Due to the effect of electrostatic discharge on or in the vicinity of CR-400, erroneous can occur. In this cace please repeat the last mesurement. If strong static electricity is received at the moment measurement is made, the measurement values may be adversely affected, but the following mea- surement will be ok.

  • Page 7: Roll Paper

    This may require the user to take suitable countermeasures. • Make sure that the power switch is set to OFF when the CR-400/410 is not in use. Use only the AC adapter (AC-A305) included with the product and connect it to a 100V AC (50/60 Hz) electrical outlet.

  • Page 8: Notes On Storage

    • Do not leave the CR-400/410 inside a car or in the trunk of a car. Under direct sunlight in summer, the increase in temperature can be extreme and may result in malfunction.

  • Page 144: Principles Of Measuring

    Principles of Measuring Principles of Measuring The measuring head measures a specimen, gets the color information from the specimen, converts it to one of the various display modes in the measuring head, and displays it. Also the data processor converts data to one of the various color space modes, displays it, and prints it. The measuring head is divided into the specimen measuring part which measures the reflected light from the specimen and the monitoring illumination part which directly measures the light from the illumination light source.

  • Page 145: Illumination Optics

    Illumination Optics Illumination Optics of the CR-400 The CR-400 is designed in diffusion illumination 0º viewing angle geometry (specular component included). This illumination method illuminates the specimen from all directions using illuminants with almost completely equal brightness, and receives the reflected light vertically from the specimen surface.

  • Page 147: Multi-Calibration Function

    <Multi-Calibration Function> The multi-calibration function is used to correct the assigned value using the calibration data in all the set calibration channels. It is therefore effective in providing an appropriate correction not only for the vicinity of the calibration target point but also for the value around it. However, since the correction effect becomes smaller for colors further from the calibration target point, more effective correction can be achieved by selecting a calibration target color which envelops the color to be measured.
