Figure 6-7. Distance and Level 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 Reference Gauge Height.

'LVWDQFH￿FDOLEUDWLRQ

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, 6, 4],

or,

RCT: open the Advanced section in the Project Bar and choose Device Commands>Basics>Set Calibration Offset.
