B4.6 Measurement display of mean values
Mean values may be acquired with two different
interval times t1 and t2. The corresponding measured
quantities are freely configurable. Therefore also the
appropriate measurement displays are variable. Up to
12 different pages may be displayed. The selection is
performed using the keys
and
.
Trend, last value t1 / t2
: Last calculated mean value
and the trend of this measurement
Maximum, minimum t1 / t2
: The extreme values of
the acquired mean values with timestamp
Reset maximum, minimum
: Allows to selectively
reset the extreme values
Mean values t1 / t2
For each selected measurand the last acquired mean
value as well as the trend value is shown.
Monitoring of trend values by means of limit values
makes sense especially for power quantities.
Maximum, minimum t1 / t2
For each configured mean value quantity the
maximum and the minimum value with timestamp
(time of occurrence) is shown.
Details about the timestamp may be found in the
chapter settings of the clock.
Reset max., min.
For all acquired values or selectively only for parts
extreme values can be reset by pressing
for al
longer time(>1s).
Note: Depending on the interval time t1 resp. t2 it may
take hours until a new extreme value is stored.
B4.7 Measurements for wiring control
The wiring check shows measurements for voltage
and current of all phases and the direction of energy
flow of the currents.
If all voltages have almost similar values and the
energy flow direction of the currents is equal it may be
assumed that the wiring has been performed
correctly.
