Measurement Item: PATT/PLN
Whether measurement is patterned or plain is determined automatically by comparing the deviation level 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.
The deviation level will become high if the sensing object has a pat-
tern. If the deviation level is higher than the set level of measurement
item selection, pattern measurement will be performed.
The portion with the highest deviation is
registered as a model.
POINT
Note:
2. Threshold Adjustment/Sample Test (MONITOR Mode)
The Sensor operates in MONITOR mode for threshold level adjustments and desktop sample tests for object discrimination with no signal
output. No external output operation signal or external input signal is accepted in MONITOR mode.
(1) Set the mode selector to MON.
Measurement continues as long as the selector is set to MON.
Pattern Measurement
On the basis of the registered model, the level indicator indicates the degree of conformity of the sensing object.

Measurement item
selection level
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 pat-
terns, pattern measurement may be performed. In this
case, by increasing the set level of measurement item
selection, plain measurement will be performed.
Do not turn OFF the Sensor before the Sensor is set to MONITOR mode, otherwise the teaching data will be lost.

The closer to the model in appearance,
the higher the level.
Plain Measurement
The deviation level will be set to low if the sensing object has no
pattern. If the set level of measurement item selection is higher than
the deviation level, plain measurement will be performed.

The deviation and average density in the area enclosed by dotted
lines are registered. The dotted lines are not projected.
Plain measurement will be performed if the pattern is close to the edge of
the sensing area.
Teaching is performed in the area enclosed
by dotted lines inside the sensing area. The
pattern close to the edge of the sensing area
is not registered as a model because such a
pattern may not be always located in the
sensing area and accurate measurement
cannot be performed. In this example, the
deviation level in the area enclosed by the
dotted lines is small. Therefore, plain mea-
surement will be performed.
Teaching Area
The deviation and average density in the teaching area are regis-
tered in the above example. In other words, the sensing area is
restricted so that the pattern close to the edge will not influence
the results of object discrimination.

If no sensing object is within the sensing
area or if the sensing object is greatly differ-
