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 oper-
ating modes:
-stored value
-storage rate
Stored value The stored value determines whether the average, minimum, maximum or in-
stantaneous value of the time interval between two storage cycles or the peak
values (envelope) are stored. When “peak value” is set, then the minimum and
maximum values of the last storage cycle are stored.
Storage rate The storage rate determines the time interval between two stored values. The
diagram speed corresponds to the storage rate, which means that at a storage
rate of 5sec, for example, the stored value is entered in the diagram every 5
sec.
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 determined (24 hrs max.) within
which a specific stored value and a specific storage rate are active.
Event operation Event operation is active as long as its operating signal (v Chapter 4.2.6
“Configuration - Measurement storage”) is active. Event operation can be
used, for example, to shorten the storage rate when an alarm is present.
Priority The respective priorities of the operating modes are allocated as follows:
