CONFIGURATION
This section covers non-standard configuration.
User defined Upper
Reference Point
If you want to specify your own Upper Reference Point you can do this by
setting the Calibration Offset parameter.
Figure 6-1. Tank Geometry
To set the desired upper reference point do the following:
1. Adjust the Reference Gauge Height to the distance from the tank
bottom to the desired Upper Reference Point.
2. Add the distance between the Upper Reference Point and the
Transmitter Reference Point to the Calibration Offset value that is
stored in the transmitter database.
With the HART Communicator the Calibration Offset is available as
HART Fast Key sequence [1, 4, 5, 5].
In Radar Configuration Tool (RCT) the Calibration Offset is available
under the Advanced section in the RCT Project Bar:
