Upper limit/Lower limit
Set the upper and lower limits (thresholds) that will be used to perform
output judgments.
Output turns on when one of the following conditions is met.
• (When “Out polar” is “N.O.”)
• The value exceeds the upper limit.
• The value falls below the lower limit.
• Measurement is not possible.
Tips: •
Thresholds are judged based on the offset value.
For example, output will turn on as shown below when the offset value is
100 mm and the upper limit is 10 mm.
Offset value (100 mm) + Upper limit (10 mm) = 110 mm
(Refer to the figure to the right. Changing the offset value will shift the
upper and lower limit accordingly.)
Out polar
• N.O.: Output turns on when a measurement result is outside the range
defined by the threshold upper limit and lower limit, or when measure-
ment is not possible.
• N.C.: Output turns on when the measurement result is within the range
defined by the threshold upper limit and lower limit.

Hysteresis
Upper limit
Output
Hysteresis
Set the amount that the value can fall below (or exceed) the threshold
before output is turned off.
This is useful in preventing chattering, the repeated turning on and off
of the output when the value is in the vicinity of the threshold.
Tips: • The threshold judgment operation is performed in accordance with the
"Out polar" and "On Timing" settings as shown in the table below.
