2.7 Operating modes
3 operating
modes The instrument has 3 operating modes:
- normal operation
- timed operation
- event operation
The following settings can, among others, be made for each of the three
operating modes:
- stored value
- storage cycle
Stored value The stored value setting determines what is stored: average, minimum,
maximum or momentary value between two storage cycles, or the peak value
(envelope). The setting “peak value” means that the maximum and minimum
values from the last storage cycle are saved.
Storage cycle The storage cycle determines the interval between two stored values. The
diagram speed corresponds to the storage cycle, which means that with a
storage cycle of 5sec, for example, the stored value is entered in the diagram
every 5sec.
Normal
operation Normal operation is active whenever event or timed operation is not active.
Timed
operation For timed operation, a period of time can be defined (up to 24 hrs) within
which a specific stored value and a specific storage cycle are active.
Event operation Event operation is active as long as its control signal (
v Chapter 4.2.6
“Configuration - Recording”) is active. Event operation can be used, for
example, to shorten the storage cycle when an alarm is present.
Priority The respective priorities of the operating modes are allocated as follows:
Active

for the diagram speed:
