SETTING
During teaching, the FZ-10 series resolves the color projected by the spot into
red, green, and blue components which are processed as numerical values and
stored into the EEPROM memory.
If, during teaching, the spot area is not filled by one uniform
color, such as when the target objects are smaller than the spot

area, or are partly projected upon, then colors other than the one
you want to detect may also be sensed. Make sure that objects

To manipulate the DIP switches, use a pair of tweezers, etc., with a tip width of 0.8mm approx.

Setting by auto-teaching
Teaching the reference color on a moving object. (If the sample object includes
colors other than the reference color, perform manual teaching. The sample object
must contain only one uniform color for correct auto-teaching.)
