About Instrument Parameters - 129
Note:
Just as in fieldbus instruments, the user interface
and manuals of HART instruments are sometimes using the
misleading term "calibration" although it is actually a trim that is
performed.
Be careful during the trimming procedure. Follow the instructions
in the instrument's user manual. Skipping a step in the
procedure may result in an unsuccessful trim.
Typically, the correct order for trimming is: digital output first,
then analog output.

be initiated from the
Documenting Calibrator
, provided the relevant
communicator option is enabled and the instrument's Device Description
contains information of parameters needed for trimming.
