This function is used to set an upper limit (threshold a), lower limit (threshold
b), and hysteresis for the judgment of measurement values.

•
Make settings so that threshold a is larger than threshold b. The sensor head will
perform automatic discrimination, however, if the opposite settings are made.
•
The decimal point position varies with each model.
● Setting Procedure
（
Setting Threshold a
）
1
Display the "Output Setting" screen
while the system is in setting mode.
2
Press the [ENTER] key. The "Judgment
Output Selection" screen will be displayed.
3
Press the [DOWN] key once. The

4
Press the [ENTER] key. The present
threshold will be displayed. The leftmost
digit will be selected.
5
Press the [UP]/[DOWN] keys together to
change the selected digit.
6
Press the [UP]/[DOWN] key to change
the selected digit or its sign. (Example:
Changing the value to +5 [mm].)
7
Press the [ENTER] key to determine the
threshold.
