5-2-5 Distance Measurement Errors
These errors are displayed only for a Reflective Sensor Head.
A distance measurement error indicates the inability to carry out measure-
ment due to an incident level error. This occurs in the following cases:
5-2-6 Laser Deterioration
will be displayed on the main display for 5 seconds when
the power is turned ON if the Sensor Head laser has deteriorated. Replace
the Sensor Head.
Insufficient incident
level:
The incident level may be insufficient when the
sensing object reflectivity is extremely small, such
as for black rubber.
Incident level satura-
tion:
The incident level may be saturated when the
sensing object reflectivity is extremely large, such
as for a mirror.
Distance error: An error may occur when the sensing object is
outside the sensing range and the reflected light
does not arrive at the correct receiver position.
