12.1 Damping Factor
Each displayed measured value is the floating average of all measured values of the last
x seconds, where x is the damping factor. A damping factor of 1 s means that the mea-
sured values are not averaged as the measuring rate is approx 1/s. The default value of
10 s is appropriate for normal flow conditions.
Strongly fluctuating values caused by high flow dynamics require a higher damping fac-
tor.
Select the program branch OUTPUT OPTIONS. Press ENTER until the menu item DAMP-
ING is displayed.
Press BRK to return to the main menu.
12.2 Totalizers
Heat quantity, total volume or total mass of the medium at the measuring point can be
determined.
There are two totalizers, one for the positive flow direction, one for the negative flow di-
rection.
The unit of measurement used for totalization corresponds to the heat, volume or mass
unit selected for the physical quantity.
The totalizer value consists of max. 11 digits, including max. 3 decimal places.
Enter the damping factor. Press ENTER.
To activate the totalizers, press key during measure-
ment (see Table 12.1).
The totalizer value will be displayed in the upper line (here:
the volume which has passed through the pipe at the mea-
suring point in positive flow direction since the activation of
the totalizers).
