Operating Mode, Storage Cycle, Event Interval and Event type
The operation mode determines when and how often the transmitter shall measure and when
and how often the measurements shall be saved. Storage cycle, event interval and event
type can be adjusted depending on the operation mode.
To choose the >Operation Mode< select from
•
>Cycle Mode<
The transmitter wakes up at the intervals set in storage cycle, executes a brief meas-
urement and saves the data. After that the transmitter goes back to “sleep mode” until
the next measurement.
•
>Event Mode<
On one hand, the transmitter behaves like being in cyclic operation, however it is possi-
ble to additionally set an event interval. The transmitter then wakes up at previously de-
fined events, measures and saves data at the adjusted event intervals.
•
>Continuous Event Mode<
In this mode the transmitter basically operates like being event operation, however
measures continuously during the event. The instrument saves the data at the adjusted
event intervals.
•
>Continuous Operation<
The transmitter measures continuously, however will save the data only at the intervals
set with the storage cycle.
>Storage Cycle<
Select from (depending on the operation mode set): (5 s, 10 s, 20 s, 30 s,) 1 min, 2 min,
5 min, 10 min, 30 min und 1 h
>Event Interval<
Available settings: 1 min, 2 min and 5 min
>Event type< (only with Event mode and Continuous event mode)
The operation modes “Event mode” and “Continuous event mode” allow to (depending on the
parameters) additionally select the event types “Flow”, “Level”, “Velocity”, “Water tempera-
ture”, “Air temperature”, “Analog input 1”, “Analog input 2”, “Analog input 3” and “Digital input
1”.
Except for “Digital input 1” the “Switching threshold” for switchover can be defined for each of
the parameters.
The indicated selection of event types varies depending on the parameter settings.
>New total<
Here either the flow rate can be reset to “0” or a new (basic) value for the flow rate can be
set. This may become necessary after transmitter replacement or as soon as the parameters
for a new measurement place need to be adjusted.
