• Enter the center of the range in which the event trigger has to be switched.
• Press ENTER.
• Enter the width of the range in which the event trigger has to be switched.
• Press ENTER.
Definition of the switching delay
• Enter a time interval after which the event trigger has to switch in case the event occurred.
• Press ENTER.
• Enter a time interval after which the event trigger has to be deactivated in case of a measurement failure.
• Press ENTER.
19.7.1 Apparent switching delay
The measured values and totalizer values will be displayed rounded according to the set number of decimal places. The
limits, however, will be compared to the non-rounded measured values. This might cause an apparent switching delay
when the measured value changes marginally (less than the visualized decimal places). In this case, the switching
accuracy of the event trigger is higher than the accuracy of the display.
19.7.2 Reset and initialization of the event triggers
After an initialization of the transmitter all event triggers are deactivated.
• Press 3 times C during measurement to set all event triggers to the idle state.
Event triggers whose switching condition is still met will be activated again after 1 s. This function is used to reset event
triggers of the type HOLD if the switching condition is no longer met.
If a measurement is stopped, all event triggers will be deactivated and the corresponding process outputs will be de-
energized, independently of the programmed idle state.
