5.6 Internal electronic totalizer
•
The internal electronic totalizer counts the volume in mathematically determined volumetric units. These numerical
values are put into a non-volatile memory (EEPROM), converted into the set physical units and displayed every 0.3
seconds.
Counting is interrupted in the event of a power failure, entry into the setting mode or when the low-flow cut off (SMU)
is activated. After these conditions have been eliminated, counting continues with the values stored prior to the
interruption.
•
The counting period without overflow is at least 1 year at 100% of flow (Q
100%
)
•
Set the time constant under fct. 3.4.5:
40 mSec
Time constant F = 0.04 seconds.
SAME AS I Same time constant as current output I
(see fct. 3.3.6)
Resetting the totalizers (TOTAL.RESET)
•
There are two ways of resetting the totalizers:
1 st way, separate resetting of “+” and “-” totalizers in
the Reset/Quit menu. Only possible if YES entered
under fct. 3.6.10 Reset Enable!
2 nd way, combined resetting of “+” and “-” totalizers.
•
The measuring mode is interrupted during the reset.
•
Before changing the numerical values in fct. 3.1.1, 3.1.5 + 3.1.6 (e.g. if the full-scale range is changed, see
fct. 3.1.1, or in the case of separate systems the signal converter is replaced, see sect. 8.2),it is advisable to
note down the totalizer counts first and then reset the totalizer otherwise an incorrect count will be
displayed.
