7. Comparison Setting

7-3. Hysteresis

This function applies a width to switching from ON to OFF for high limit and low limit judgment display.
If the indicator value fluctuates near a value, causing judgment display to chatter between ON and OFF, adjustment of the hysteresis
value can prevent this chattering.
The operation of hysteresis changes as follows according to the Comp. Pattern Setting.
For limit boundary values that are greater than the OK position, it operates in the negative direction. For limit boundary values that
are less than the OK position, it operates in the positive direction.
When the Comp. Pattern Setting is LO/OK/HI, hysteresis activates for the high limit value when an indicator value decreases.
