Measurement Item: PATT/PLN
Whether measurement is patterned or plain is determined automatically by
comparing the contrast with the background within the detection range. When
teaching is finished, all the level indicators will light for 0.5 s, and the buzzer will
sound twice.
Pattern Measurement
The deviation level will become high if the senseing object has a pattern. If the
deviation level is htgher than the set level of measurement item selecton,
pattern measurement will be performed.
Detection Range
A
The portion with the highest
deviation is registered as a
model.
The set level of measurement item selection is increased or
decreased by pressing the SELECT buttons. Adjust the level
according to the background and deviation. The level is factory-
set between 2 and 3.
If the object has some light-color lines or light-color patterns,
pattern measurement may be performed. In this case, by
increasing the set level of measurement item selection, plain
measurement will be performed.
Note: Do not turn OFF the Sensor before the Sensor is
set to MONITOR mode, otherwise the teaching data will
be lost.

Plain Measurement
If the set level of measurement item selection is higher than the deviation
level, plain

Plain Measurement with A.T.OFF
The deviation and average
density in the Teaching area
are registered.

*) By another mode, it is possible to enlarge Detection Range.
Plain Measurement with A.T.ON
The deviation and average density in
the area enclosed by dotted lines are
registered.
