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 8SSHU￿5HIHUHQFH￿3RLQW.

2.Add the the distance between the 8SSHU￿5HIHUHQFH￿3RLQW and the 7UDQVPLWWHU￿5HIHUHQFH￿3RLQW￿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, 3, 7].

In Radar Configuration Tool (RCT) the Calibration Offset is available under the Advanced section in the RCT Project Bar:

Device Commands>Basic>Set Calibration Offset.
