OPERATION PROCEDURE FOR USING THE C/C+I MODE
■
Description of indication
Matching rate
Displays the degree of correspondence between the target color calibrated
as a reference and the target color currently being detected.
Setting range: 0 to 999 (larger value for higher matching rate)
Setting value
Displays the threshold value that judges how much correspondence between
the color of the current target and the color of the target calibrated as a refer-
ence is considered as an identical color.
Received light intensity
Displays the amount of light currently received.
Power mode (response time)
Displays the power mode currently being selected.
Setting a sensitivity
For selecting a calibration mode, refer to page 5.
■
1-point calibration (for detecting a single specified color)
Place a target of which color is to be used as a reference onto the focus posi-
tion of the beam spot emitted from the sensor. Then press the SET button once.
• The set value appears in green.
■
2-point calibration (for discriminating two colors)
1
Place a target of which color is to be used as a reference onto the focus
position of the beam spot emitted from the sensor. Then press the SET
button once.
"SET" appears in green on the setting value monitor.
2
Place a target of which color is to be discriminated. Then press the SET
button once.
• The set value appears in green.
■
Pinpoint calibration (1-point calibration with a stricter criterion)
Suitable for performing a stricter detection than 1-point calibration.
The setup method is the same as that for 1-point calibration.
• The setting value becomes larger than that of 1-point calibration even if the
same target is used for calibration.
Fine-adjusting a sensitivity
■
Fine-adjusting a sensitivity by changing the setting value
The larger the setting value, the stricter the detection becomes, and the
smaller the setting value, the rougher the detection becomes.
To change the setting value (displayed in green digits), press the UP or
DOWN button.
■
Fine-adjusting by using a target
Fine-adjust the setting value by performing an adding or eleminating calibra-
tion.
Adding calibration (setting-value decreasing calibration)
Set the target to be judged as an identical color. While holding down the SET
button, press the DOWN button.
Eliminating calibration (setting-value increasing calibration)
Set the target not to be judged as an identical color. While holding down the
SET button, press the UP button.
Permitting uneven color
At a 1-point calibration or a pinpoint calibration, the sensor continues sam-
pling while the SET button is held down.
• The sampled colors are set to be judged as an identical color.
Setting value
At the sensitivity setting, the sensor automatically determines the setting
value. The setting value can also be preset to a fixed value manually. In that
case, perform the following operation.
Press the UP and DOWN buttons at the same time for three seconds or more.
• "F" appears in green on the left-hand side of the setting value monitor.
The cancellation method is the same as the method of fixing the setting value.
With the “F” being on display, the setting value does not change from the
fixed value even if the sensitivity setting is performed.
Note
If the sensitivity difference is insufficient, the setting value monitor shows
"- - - -" in green.
