Sets an appropriate sensitivity according to the change in target surface
condition.
Set the sensitivity to AUTO for normal use.
AUTO:
Used to measure various objects: from objects with low reflectance such
as black rubber, to ones with high reflectance such as metals.
Note: If the reflectance of the target changes greatly during a short
cycle, the analog output may become unstable with the AUTO setting.
In this case, set the sensitivity to HIGH or LOW.
HIGH:
Fix the sensitivity to high. Used to measure a part with low reflectance
(black) in the above condition.
LOW:
Fix the sensitivity to low. Used to measure a part with high reflectance in
the above condition.
FUNCTIONS SENSITIVITY SETTING
Example: Measurement of pin warpage
In the measurement of the warpage of moving pins, the reflectance of
the pin and gap change greatly during a short cycle. To measure such a
target, set the sensitivity setting switch to LOW and measure only pins
which have high reflectance.
