Level and Distance 
Calibration

When calibrating the transmitter it is important that the product surface is calm 
and that the tank is not being filled or emptied.

A complete calibration is performed in two steps:

1. Calibrate the Distance measurement by adjusting the Calibration Offset 

parameter.

2. Calibrate the Level measurement by adjusting the Tank Height.

Distance calibration

1. Measure the actual distance between the Upper Reference Point and the 

product surface.

2. Adjust the Calibration Offset so that the Distance measured by the 

transmitter corresponds to the actual distance. 
The Calibration Offset parameter is available via 
HART command [1, 4, 5, 5],
or
RCT: open the Advanced section in the Project Bar and choose Device 
Commands>Basics>Set Calibration Offset.

Level calibration

1. Measure the actual Product Level.
2. Adjust the Tank Height so that the measured Product Level corresponds 

with the actual level.
