The number of decimal places is constant. The max value of the totalizer is reduced with the number of decimal places.
17.1.2 Detection of long measurement failures
If there are no valid measured values during a long time interval, the totalizers remain unchanged.
The time interval can be defined.
• Select the menu item Totalizers in the program branch Special functions.
• Press ENTER until the menu item Totalizer timeout is displayed.
•Select Default if no user-defined inputs are to be carried out and the default value of 30 s is to be used.
• Press ENTER.
•Select User-defined if the time interval is to be defined.
• Press ENTER.
• Enter the time interval.
• Press ENTER.
17.1.3 Totalizer overflow
The overflow behavior of the totalizers can be set:
Without overflow
• The value of the totalizer increases to the internal limit of 10
38
.
• The values will be displayed as exponential numbers (±1.00000E10), if necessary. The flow totalizer can only be reset to
zero manually.
With overflow
The flow totalizer will be reset to zero automatically when ±9999999999 is reached.
• Select the menu item Totalizers in the program branch Special functions.
• Press ENTER until the menu item Overflow behavior is displayed.
•Select Yes to work with overflow. Select No to work without overflow.
• Press ENTER.
Independent of the setting, the flow totalizers can be reset to zero manually.

Notice!
The overflow of a totalizer influences all output channels, e.g., data logger, online transmission of data.
The output sum of both totalizers (throughput Q) transmitted via an output is no longer valid after the overflow of one
of the totalizers.
