WARNING!
During the calibration, the relays and analog output signals assume the config-
ured states!
Universal inputs can be configured with various operation modes for a number
of different process variables (see table below).
Detailed information on the possible configurations:
v Chapter 9.5.2 "Universal inputs of base unit and optional boards", Page 99
Appropriate calibration routines for each operation mode of a universal input can
be enabled in the calibration default settings.
The following table lists the availability of calibration routines for the individual
operation modes.

This calibration method is used to determine the pH zero point on a measure-
ment characteristic curve. The slope is retained.
A test solution with a defined value of the respective process variable is needed
as a reference.
