4-12 ITEM Overview (HUE)
Use this item to measure the color of measurement targets. The color has
three parameters (hue, saturation, Value). Averages of three parameters and
deviations (fluctuations) of three parameters are output. This item cannot be
used when connecting a monochrome camera.

(hue: 240) : area of 20%
Orange (hue: 60) : area of 80%
Average of HUE
240 * 20 + 60 * 80 = 96

Measurement of deviation is stable without external noise. Therefore, it is possible to
set the threshold if the difference between passed products and non-passed products
is small.
