17.2 General information
17.2.1 Calibration methods for universal inputs
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:
⇨
Chapter 10.6.2 "Universal inputs of base unit and optional boards", page 17
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.
Zero-point calibration
This calibration method is used to determine the zero point on the measurement
characteristic curve. The slope is retained.
A test solution with a defined value of the respective measurand is needed as a
reference.
Slope calibration
This calibration method is used to determine the slope of the measurement
characteristic curve. The zero point is retained.
A test solution with a defined value of the respective measurand is needed as a
reference.
WARNING!
During the calibration, the relays and analog output signals assume the states
configured for the calibration! The response of the output signals is set for each
output in its "Response at calibration" configuration point.
