Settings depend on the
measured value
Operating mode
=
Change rate
The slope of the measured value (MV) is
monitored in this mode.
If, in the specified time frame (
Delta time
), the
measured value increases or decreases by more
than the specified value (
Delta value
), an event
is generated. No further event is generated if the
value continues to experience such a steep
increase or decrease. If the slope is back below
the limit value, the alarm status is reset after a
preset time (
Auto Confirm
).
Events are triggered by the following conditions
