OPERATING PROCEDURE FOR USING C OR C + I MODE
Setting sensitivity
Calibration indicator
■ 1-point calibration (Detection of one specified color)
Place a target that is the reference color in the detection area of the
fiber unit. Press the SET button and then release it.
The calibration indicator illuminates momentarily and the reference
color is saved.
MODE
SET
N.O N.C OFF DLY.
OUT TIM SET
Press this
button once.
● To ignore certain color differences
There are two methods for ignoring color differences.
• Perform the sensitivity adjustment after calibration. ( ➞ See the lower
right part of page 4.)
• Use the quick color difference cancellation function.
In 1-point calibration, hold down the SET button and continue the
calibration with targets of different colors. The CZ-K1(P) Series
ignores the color vibration and saves them as the reference color.

Hold down the
SET button.
■ 2-point calibration (Differentiation of two colors)
1. Place a target that is the reference color in the detection area of the
fiber unit. Press the SET button and then release it.
The calibration indicator illuminates and the reference color is
saved.
2. Place a target that is the color to be differentiated in the detection
area. Press the SET button and then release it.
The calibration indicator goes off. The CZ-K1(P) Series sets the
optimal sensitivity to differentiate the two colors.

● When “- - -” is displayed:
When the sensitivity difference is insufficient for proper detection, the
LCD display monitor shows “- - -” for 3 seconds after calibration.
In this case, see “When calibration/differentiation fails” on the upper
right part of this page and try the calibration again.
● When calibration/differentiation fails
Check the following points.
• Check whether the fiber unit is mounted properly (detection
distance and detection angle). (See page 7.)
• Perform the sensitivity adjustment. (See below.)
• Select the other differentiation mode and then perform calibration
again. (See page 3.)
LCD display indication
Current value
(Matching rate display)
● Matching rate display
Displays the matching degree
(matching rate) of the color of the
currently detected target to the
reference color registered during
calibration.
* Displays a value between 0 and 999.
(Higher value indicates a better match.)

MODE
Press the button once.
Setting value
The setting value
flashes on and off.
● Setting value display
Displays the threshold value
(criteria) of the matching rate to
determine if the color of the
currently detected target is the
same color as the reference color.
When “nnn nnn nnn nnn nnn” or “VVV VVV VVV VVV VVV” is displayed
These displays indicate that the received light is insufficient or
excessive.
➞ See page 7.
Sensitivity adjustment
The tolerance of the detection can be adjusted.
1. Press the MODE button to show the setting value.
2. Press the UP/DOWN button to change the setting value.

Press
A higher value means
precise detection.
Press

A lower value means
rough detection.
