False signal suppression
High sockets and internal vessel installations cause interfering reflec-
tions and can influence the measurement.
A false signal suppression detects, marks and saves these false
signals so that they are no longer taken into account for the level and
interface measurement. We generally recommend carrying out a false
signal suppression to achieve the best possible accuracy. This should
be done with the lowest possible level so that all potential interfering
reflections can be detected.
Enter the actual distance from the sensor to the product surface.
All interfering signals in this section are detected by the sensor and
stored.
The instrument carries out an automatic false signal suppression
as soon as the probe is uncovered. The false signal suppression is
always updated.
AI FB1 Channel
In this menu item you can select the function of the first Function
Block. AI stands for Analog Input.
With this you can adjust the value for the Primary Value (PV). Further
settings (SV, TV) must be carried out via PACTware.
6.4 Parameter adjustment - Extended adjustment
For technically demanding measurement loops you can carry out
extended settings in "Extended adjustment".
The main menu is divided into five sections with the following func-
tions:
Setup: Settings, e.g. measurement loop name, medium, application,
vessel, adjustment, AI FB 1 Channel - Scaling - Damping, device
units, false signal suppression, linearization
Display: Language setting, settings for the measured value indication
as well as lighting
Diagnosis: Information, for example on the instrument status, pointer,
reliability, AI FB 1 simulation, echo curve
