Select the command →Clear totalizer in the upper line to reset the totalizers to zero. Press ENTER.
Automatic toggling between the displays
Select Special Funct.\SYSTEM settings\Storing\Toggle totalizer to toggle automatically between the
flow totalizer displays for the positive and negative flow direction.
Selection of the totalizers for storing
It is possible to store only the value of the totalizer that is currently displayed or one value for each flow direction. Select
Special Funct.\SYSTEM settings\Storing\Quantity Storage.
When the measurement is stopped
The behavior of the totalizers when the measurement is stopped or after a RESET of the transmitter is set in Special
Funct.\SYSTEM settings\Measuring\Quantity recall.
11.3.1 Overflow of the Totalizers
The overflow behavior of the totalizers can be set:
Without overflow:
• The value of the totalizer increases to the internal limit of 10
38
.
• If necessary, the values will be displayed as exponential numbers (±1.00000E10). The totalizer can only be reset to zero
manually.
With overflow:
• The totalizer will be reset to zero automatically when ±9999999999 is reached.
Select Special Funct.\SYSTEM settings\Measuring\Quant. wrapping.
Independently of the setting, the totalizers can be reset to zero manually.
This error message will be displayed if the totalizers of a measuring channel used for mea-
suring the flow velocity are to be activated. The flow velocity cannot be totalized.
Enter a time interval between 0 (off) and 5 s. Press ENTER.
If one is selected, only the totalizer whose value is changing will be stored. This can apply
to the totalizer for the positive or the negative flow direction.
If both is selected, the values of the totalizers for both flow directions will be stored.
Press ENTER.
If on is selected, the values of the totalizers will be stored and used for the next measure-
ment.
If off is selected, the totalizers will be reset to zero.
Select on to work with overflow. Select off to work without overflow. Press ENTER.
Note! The transmission of the sum of both totalizers (the throughput Q) via an output will not be valid after
the first overflow (wrapping) of one of the corresponding totalizers.
To signalize the overflow of a totalizer, an alarm output with the switching condition QUANT. and the
type HOLD have to be activated.
