Outline of the Calibration/Settings Section

This section explains settings that must be configured according to measurement method.
Available measurement methods and the settings that must be made are explained below.
1� Measurement using Konica Minolta's Calibration Standard
With this method, measurement is performed using Konica Minolta's calibration standard without calibration.
Even when setting the target value to calibration channel CH00, measurement must be performed as explained below.
It is not necessary to set/change the target value if the color difference display function will not be used.
Operating Procedure
When using only the absolute value display

2� Measurement using user calibration
With this method, user calibration is performed and the obtained correction coefficient is used for measurement.
Because the target value is also set, the color difference display section can show the deviation of the measured values from
the target value. User calibration must be performed in the following cases. (However, it is not possible to perform user
calibration using calibration channel CH00.)
• To correct variation of readings that occur due to the deviation of spectral sensitivity from the CIE 1931 color matching
function
• To correct differences in readings between probes when two or more probes are used

• User calibration details:
• To change the target after user calibration: Refer to page 82 "Setting/Changing the Target"*
• To set an ID:
*1 About "Setting/Changing the Target"
The following two methods can be used for setting/changing the target.
(1) Setting/changing the target by measurement
(2) Setting/changing the target by entering values
*2 About "Setting an ID"
An ID is useful when specifying that the user calibration and target value have been set for a specific type of display
with specific colors.
