Measurement types and measuring ranges

Introduction
SM 331; AI 2 x 12 Bit is equipped with a measuring range module. The measurement type
and range is configured at the "measuring range" parameter in
default "voltage" measurement type and "± 10 V range without having to program the
SM 331; AI 2 x 12 Bit in
Measuring range module
Change the position of the measuring range module to set the measurement type and range
(see the chapter
necessary settings are also available on the module's imprint. Mark the position of the
measuring range module on the front door (see figure).
