Pressure gauge zero drift issue

The range of the Rosemount pressure transmitter is from -3 to 3 Kpa; the value corresponding to atmospheric pressure is 0.03 Kpa, and zeroing is required. The instrument on site does not have a zeroing button, so a 475 device must be used for this purpose. By migrating from 3.03 to 2.97, the values displayed on-site will not match those shown on the DCS. Is there any other method besides the one mentioned earlier?

The header display can be modified to correspond to DCS

Separate the table header from the atmosphere; use 475 to access the zeroing menu and perform zeroing directly

No adjustment is needed; the local atmospheric pressure is not necessarily 101.325, and migration and zeroing are not the same thing.
