13 Storing and Output of Measured Values
13.4.2 Sample Mode
13.4.3 Storing of the Totalizers
It is possible to store only the totalizer value currently displayed or one value for each
flow direction.
Select
SPECIAL FUNCTION\SYSTEM SETTINGS\STORING\QUANTITY STORAGE
.
Select the sample mode.
If
SAMPLE
is selected, the displayed measured value
will be used for storing and online output.
If
AVERAGE
is selected, the mean value of all measured
values during a storage interval will be used for storing
and online output.
Press ENTER.
Note!
The sample mode does not have influence on the interfaces working
continuously (e.g. current output, voltage output).
If
AVERAGE
is selected, all primary physical quantities will be aver-
aged, i.e. also the measured temperatures if the corresponding mea-
suring channel is activated.
Note!
If a mean value could not be calculated over the complete storage in-
terval while
AVERAGE
was activated, the value will be marked as in-
valid. "???" appears in the ASCII file of the stored measured values
for invalid mean values and the corresponding physical quantity and
"?UNDEF" for invalid temperatures. There will be no indication of
how many momentary measured values a valid mean value consists
of.
Select
ONE
to store only the displayed totalizer.
Select
BOTH
to store the totalizer of both flow directions.
Press ENTER.
Note!
The totalizers will be stored only if they are activated and the data
memory is activated.
Storing of a totalizer reduces the total number of measured values to
be stored by approx. two thirds.
example: It is displayed in the program branch
SPECIAL FUNCTION
that 10 000
measured values can still be stored. If the totalizers are activated and
only one totalizer is stored, 3 333 data fields will be available for storing.
If both totalizers are stored, 2 000 data fields will be available for storing.
