Zero trim the transmitter

Note
Transmitters are shipped fully calibrated per request or by the factory
default of full scale (span = upper range limit).
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.
The transmitter will only allow three to five percent 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.
