Basic Configuration/Start-up
Distance calibration
1. Measure the actual distance between the Upper Reference Point and the product
surface.
2. Adjust the Calibration Distance so that the Distance measured by the transmitter
corresponds to the actual distance.
The Calibration Distance parameter is available via
HART command [2, 3, 2, 4, 1],
or
RRM:
a. Select the Tank icon under Device Config/Setup in the RRM workspace.
b. In the Tank window, select the Geometry tab.
c. Select the Advanced button.
d. Enter the desired value in the Calibration Distance field and select the Store button.
Level calibration
1. Measure the actual Product Level.
2. Adjust the Tank Height so the product level measured by the transmitter corresponds
to the actual product level.

5.3.7 Echo tuning
When Basic Configuration is performed, the transmitter may need to be tuned to handle
disturbing objects in the tank. There are different methods available for handling disturbance
echoes with the Rosemount 5400 Series Transmitter:
ATC
False echo registration, see “Registration of false echoes” on page 135
The Guided Setup in the RRM configuration program includes a Measure and Learn function which
automatically registers false echoes and creates an ATC (see “Guided setup” on page 92).
The created ATC is based on the present tank spectra and process condition settings.
Disturbances below the product surface might not be handled by the Measure and Learn
function.
