PRESSURE TRIM [TRIM]

This field of the tree is used to adjust the digital reading according to the applied pressure. The pressure TRIM
differs from RANGING WITH REFERENCE, since the TRIM is used to correct the measure and RANGING
WITH REFERENCE reach only the applied pressure with the output signal of 4 to 20 mA. Figure 4.8 shows
the options available to run the pressure TRIM.
