Limits with hysteresis
If you enter a non-zero value in the "Hysteresis" text box, the hysteresis is disabled.
Upper limit with hysteresis (A)
An overrun event is counted when the process value rises above the upper limit
①
.
The next overrun event is counted when the process value falls below the lower limit minus the
entered hysteresis
②
and then rises above the upper limit
③
.
Two events are counted in the displayed time period within 'A'.
