6.4.7 How to make the device follow the correct level or interface signal
If the distance measurement stays on one value when the level of the product changes, the
device has probably selected a parasitic signal as the level signal. You can set the device to the
correct value with the Distance Input
Distance Input Distance Input Distance Input function.
The Distance Input Distance Input Distance Input Distance Input function, used with the signal screen, makes the device look for the level or
the interface (if the device is configured for interface applications) at the correct point along the
probe. A distance value must be given by the supervisor. The distance is measured from the
flange facing or thread stop to the surface of the product.
The signal screen is divided into 4 areas, as shown in the illustration that follows:
INFORMATION!
When you create a table, get more conversion data for parts of the tank where there are:
• Surfaces with curves.
• Sudden changes in the cross section.
This will make volume measurement more accurate.

CAUTION!
Do not give a distance value that is in the dead zones of the device. For more data, refer to
Measurement limits on page 141
