If you want to specify your own Upper Reference Point you can do this by
setting the &DOLEUDWLRQ2IIVHW parameter.
Figure 6-1. Tank Geometry
To set the desired upper reference point do the following:
1. Adjust the 5HIHUHQFH*DXJH+HLJKW to the distance from the tank
bottom to the desired 8SSHU5HIHUHQFH3RLQW.
2. Add the the distance between the 8SSHU5HIHUHQFH3RLQW and the
7UDQVPLWWHU5HIHUHQFH3RLQWto 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, 3, 7].
In Radar Configuration Tool (RCT) the Calibration Offset is available
under the Advanced section in the RCT Project Bar:
