Totalizer overflow
The overflow behavior of the totalizers can be set:
• Select
Special Funct.\SYSTEM settings\Measuring\Quant. wrapping
.
• Select
on
to work with overflow.
The flow totalizer will be reset to zero automatically when ±9999999999 is reached.
• Select
off
to work without overflow.
The value of the totalizer increases to the internal limit of 10
38
. The values will be dis
-
played as exponential numbers (±1.00000E10), if necessary. The flow totalizer can only
be reset to zero manually.
• Press ENTER.
Independent of the setting, the flow totalizers can be reset to zero manually.

NoiseTrek parallel beam mode
The NoiseTrek parallel beam mode works with parallel mounted transducers. It improves

Special Funct.\SYSTEM settings\Measuring\Quant. wrapping
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 not
valid after the first overflow (wrapping) of one of the totalizers.
In order to signalize the overflow of a totalizer, an alarm output with the switching
condition
QUANT.
and the type
HOLD
has to be activated.
