Blind adjusting zero point

Introduction
With blind adjustment, you set the pressure value of the zero point continually and without
reference pressure.
Note
Changes to modes 5 and 6 effect the pressure scaling only. The scaling for level or user-
specific characteristic curve remains unaffected by it. Therefore only pressure measured
values and pressure units are displayed in these modes.
It is possible to switch between a rising and falling characteristic curve.
Requirement
You are familiar with the correct operation of the transmitter and the associated safety
information.
There is no reference pressure and you have selected a pressure unit.
Procedure
To blind adjust the pressure value of the zero point, proceed as follows:
1. Set mode 5.
2. Adjust the pressure value of the zero point.
3. Save with the <MODE> key.
