1. About Calibration Channels

A probe has calibration channels from CH00 to CH99 (100 channels in total).
The following can be set for each of CH00 to CH99:
(1) Correction coefficient for user calibration
(2) Target
(3) ID
CH00 is a channel for calibration in accordance with the Konica Minolta calibration standard. It can only be used for setting
targets or IDs.
Users can use CH01 to CH99 for calibration or saving targets.
Under the initial settings, CH01 to CH99 are also provided with the same Konica Minolta calibration value as with CH00.
Each channel can also be assigned with an ID.

2. About Targets

Targets become the base color for measuring how different another measurable color is, which is required for color
difference display. Targets can be set for each probe of each calibration channel.
Targets are set after the following operations:
(1) User calibration: After user calibration, the calibration value is set as a target at the same time.
(2) Setting/changing a target: To be performed in the following cases:
• If a correction coefficient for user calibration is input, a target is set at the same time, which erases the previously set
target.
• To change a set target, set/change a target. Changing a target does not change the correction coefficient set for user
calibration.
In a same calibration channel, the target is saved to common channel, irrespective of measurement mode.
As a result, the target set last is saved, irrespective of measurement mode.
For one calibration channel and one probe number:
• The correction coefficient for user calibration is common to xyLv mode, TduvLv mode, u'v'Lv mode, and XYZ mode.
• The target is common to all measurement modes.

• To set a target in calibration channel CH00
• To set a different color from user calibration as a target in a user-calibrated calibration
channel
• To perform measurement without performing user calibration but in accordance with the
Konica Minolta calibration standard and to use color difference display
