You can check the validity of a measurement by checking the number of edges in the
measuring range.
The examples of use are as follows.
• Preventing abnormal values from being measured due to dust, oil, etc. stuck to the
measurement part (Setting B).
• Detecting a foreign object incorporated (setting A or B)
• Confirming that the target is inserted into the measurement range (setting A)
Number of edges-setting screen
When the setting A or setting B is set, the display goes to the number of edges-setting
screen. (When OFF is set, this screen is skipped.)
Press
S / T button on the number of edges-setting screen to specify the number of edges.
The number of edges being measured is displayed on the main display (upper level).

Setting A
If the number of edges of the target differs from the
specified number, the check indicator [CHECK] lights up
and the edge check output (green wire) is turned ON.
"Power/Input-output cable" (page 2-7)
Setting B
If the number of edges of the target differs from the specified
number, the check indicator [CHECK] lights up and the edge
check output (green wire) is turned ON. However, if the
number of edges of the object is 0 (when the object cannot
be measured), the check indicator [CHECK] is turned off
and the edge check output is turned OFF.
"Power/Input-output cable" (page 2-7)
Reference
• Set B if you wish to distinguish between the case that the object is not
present within the measurement range and the case that the number of
edges of the object differs from the specified number.
• The above explanation is applicable to the case when the output mode of
judgment output is Normal Open (default value). Only ON/OFF of the edge
check output is reversed for Normal Close.
