Definition of the switching delay
• Enter a time interval after which the event trigger has to switch in case an event occurred.
• Press ENTER.
• Enter a time interval after which the event trigger has to be deactivated in case of a measurement failure.
17.7.1 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 displayed decimal places). In this case, the switching accura-
cy of the event trigger is higher than the accuracy of the display.
17.7.2 Reset and initialization of the event trigger
After an initialization of the transmitter all event triggers are deactivated.
• Press 3 times key C during measurement to set all event trigger to the idle state.
Event trigger whose switching condition is still met will be activated again after 1 s. This function is used to reset event trig-
ger of the type HOLD if the switching condition is no longer met.
If a measurement is stopped, all event trigger will be de-energized, independently of the programmed idle state.
17.7.3 Event trigger during the measurement
An event trigger with the switching condition MAX (x>limit), MIN (x<limit), Within range or Out of range will
be updated max. once per second to avoid a constant switching of the event trigger (i.e. fluctuation of the measured val-
ues around the value of the switching condition).
An event trigger with switching condition ERR (x=fail) will be activated during a measurement failure.
An event trigger of the type Non-hold will be activated if the switching condition is met. It will be deactivated if the switch-
ing condition is no longer met. The alarm remains activated for at least 1 s even if the switching condition is met for a
shorter period of time.
An event trigger of the type Hold will be activated if the switching condition is met. It remains activated even if the switch-
ing condition is no longer true.
An event trigger of the type Hold for a while will be activated if the switching condition is met. In the menu item Hold
interval the time is defined when deactivation takes place.
17.7.4 Status display of the event trigger
The state of the event trigger is displayed during the measurement.
• Press key to scroll through the second line from below until the event trigger status is displayed.
The status display of the event trigger is structured as follows.
Rx = with X being the number of the event trigger and a pictogram according to Tab. 17.6.
Options\Event trigger\Enable Rx\Source item\...\Glitch interval
Options\Event trigger\Enable Rx\Source item\...\Failure delay
There is no visual or acoustic indication of event trigger switching.
