High voltage
High voltage increases the excitation voltage of the transducers. When measuring using the correlation principle, high
voltage is deactivated by default.

On
to activate high voltage.

13.1.6
Averaging factor of the measurement
The averaging factor of the measurement defines a time range in which the values are averaged for calculation. A high
factor increases the measurement stability, but also the response time to changed measured values.

ExpertUser mode
Some menu items that are not visible in the StandardUser mode are displayed.
13.2.1
Limit of the flow velocity
Single outliers caused by heavily disturbed surroundings can appear among the measured values of the flow velocity.
If these outliers are not ignored, they will affect all derived physical quantities, which will be unsuitable for the integration
(e.g., pulse outputs).
In the ExpertUser mode it is possible to enter a limit for the flow velocity.
It is possible to ignore all measured flow velocities higher or lower than the preset limit. In this case an error will be output.

Notice!
The ExpertUser mode is intended for experienced users with advanced application knowledge.
Changed parameters can affect the StandardUser mode and lead to wrong measured values or to a measurement
failure when setting up a new measuring point.
Notice!
Some of the defined parameters remain activated when switching to the StandardUser mode. These parameters are
displayed but cannot be changed.
