FLUXUS F808, F809 12 Advanced measuring functions
114 UMFLUXUS_F808_8091V1-2-1EN, 2019-08-23
The values of the totalizers can be displayed with up to 11 places, e.g., 74890046.03. For the adjustment of the number
of decimal places (max. 4 places) see section 16.7.
Press ENTER while a totalizer is displayed to toggle between the displays of the totalizers for the two flow directions.
Select the command →Clear totalizer in the upper line to reset the totalizers to zero. Press ENTER.
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.
12.3.1 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.
Press key to scroll through the upper line to the display of the totalizers.
The value of the totalizer will be displayed in the upper line (here: the volume which has
passed the measuring point in the positive flow direction after the activation of the totaliz-
ers).
This error message will be displayed if the totalizers of a measuring channel used for mea-
surement of the flow velocity, are to be activated. The flow velocity cannot be totalized.
If one is selected, only the value of the totalizer that is currently displayed will be stored.
If both is selected, the values of the totalizers totalizer 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 overflow of a totalizer influences all output channels, e.g., data logger, online transmission of data.
The transmission of the sum of both totalizers (the throughput Q) via an output is no longer valid af-
ter 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.
