5-3. Hysteresis
The Hysteresis function provides a range of high/low limit comparator off. Usually the
high limit comparator is turned on when the indicated value is above the high limit value
and turned off when below. If you set a hysteresis range, the comparator is turned off
when the indicated value is below the high limit value by the hysteresis setting. This is
effective in preventing chattering caused when signals are slightly varying （ vibrating) .
〈 Comparison conditions 〉
・ High limit
ON conditions ： Indicated value ＞ High limit value
OFF conditions ： Indicated value ≦（ High limit value － Hysteresis set value ）
・ Low limit
ON conditions ： Indicated value ＜ Low limit value
OFF conditions ： Indicated value ≧（ Low limit value ＋ Hysteresis set value ）
