6.5.6 Trimming the zero point

Introduction

The zero point is calibrated in mode 7. Zero point calibration corrects zero point errors resulting

from the installation position of the pressure transmitter. The device type determines the way

in which you proceed.

SIMATIC PDM or the HART communicator will display the total of all zero point corrections.

Condition

You are familiar with the correct operation of the transmitter and the associated safety notes.
