The totalizer adds up the instantaneous
values with a sampling rate of 1 per second. These values, when added together,
give a very large resulting number which
normally exceeds the display range.
Hence, it is necessary to apply a conversion to bring the result within the display
range. This is carried out with the help of
factors and scaling.
EExxppllaannaattiioonn::
If the display shows a value
of 12.345 and this is totalled over an hour,
then 3.600 values of 12.345 each give a result of 44.442,000. This value can be displayed only if it has been divided by 1.000.
Thus the display shows 44.442.
The displayed total value will be derived
from the result in the totalizer, leaving the
decimal point free to be set as required.
NNoottee::
To optimize the accuracy, it is
recommended to make use of the full
totalizer display range. This is also valid
for the instantaneous value so far as it is
possible to display the total scaling with a
reasonable number of decimal digits (least
possible rounding effects).
The totalizer value can be reset (set to 0)
either via an electrical signal or manually
using the red key.
If the totalizer value exceeds the range
99999 the display blinks once per second.
NNoottee::
In the event of a power failure the
totalizer value is saved.

This value is always represented with
three places after the decimal point. If set
to 0.000 (no threshold) all input values are
processed by the totalizer.
NNoottee::
With the ranges 4 … 20 mA and
2 … 10 V an interruption at the input signal
may have the undesired effect that the
value in the totalizer goes down;
this is because the input signal has fallen
below the lowest input signal and this may
be interpreted as a negative instantaneous
value.
