This is normal for this instrument. ● As this instrument is typically used for noncontact measurements, typically at a distance of one or more feet, it is critically important that all measurements be made in a completely darkened environment. ● Contact measurements can be made using one of the flexible probe options, but care must be taken to properly mount the probe so that it is perpendicular to the display surface. ● For best results, be sure to follow the recommended instrument recalibration schedule. Konica Minolta CA-310 colorimeter The Konica Minolta CA-310 is high-speed colorimeter. Designed for both independent measurement and to be driven externally, the instrument comes in two parts: the main body, containing the core logic hardware, and a lightweight measurement probe. The instrument should be connected to the monitor using a USB A to USB B cable. Configuration The instrument must be set to xyLv measurement mode. Most critically, as this device is a colorimeter, a user calibration (both white point and matrix) must be performed prior to any display measurements being made. The user calibration can be stored in any memory channel, but that channel must be selected prior to connecting the instrument to the display. Usage guidelines Please note the following tips and guidelines when using the Konica Minolta CA-310 with the display: ● The display may take up to ten seconds after instrument connection to display the first calibration menu. This is normal for this instrument. ● Black level (zero) calibration must be performed each time after the instrument is powered on. If calibrating multiple displays, Konica Minolta recommends that zero calibration be performed every hour, especially if calibrating to a low luminance target, such as 48 cd/m2. ● Confirm that the instrument has been properly calibrated and the memory channel you calibrated is active. ● Direct contact measurement is recommended using the standard hood. This allows you to calibrate the display under typical room lighting (though dimmed lighting is still recommended for best black measurements). If using noncontact measurement, the instrument distance can be no more than 30 mm from the display surface. It is also strongly recommended that you use a completely darkened environment for noncontact measurement. Using external measurement instruments 69
