Checking reflection quality/contrast quality
Reflection quality
(Contrast quality)
Check the reflection quality or contrast quality via the display of the eva-
luation unit. The bar graph represents the quality of the reflection of the
individual LEDs in the sensor. To determine the quality of the reflection,
select the appropriate LED and illuminate a surface.
You can select between the following LEDs:
• R: Red LED
• G: Green LED
• B: Blue LED, or
• W: White light (R + G + B: all LEDs).

For the overall menu structure see Page 31, Fig. 17.
Example
The white light is used.
The bar graph values correspond to 0 to 16,000. The two narrow, rectangu-
lar, red marks at the top and bottom display a reference position at which
a calibrated white surface reflects 90 %. This corresponds to a value of
5,000 ans is the reference value.
