Zero trim the transmitter

A zero trim is a single-point adjustment used for compensating mounting
position and line pressure effects. When performing a zero trim, ensure the
equalizing valve is open and all wet legs are filled to the correct level.
Note
Transmitters are shipped fully calibrated per request or by the factory
default of full scale (span = upper range limit).
The transmitter will only allow 3–5% URL zero error to be trimmed. For
greater zero errors, compensate for the offset by using the XD_Scaling,
Out_Scaling, and Indirect L_Type which are part of the AI Block.
