Alignment of the analog inputsIn this chapter you can read about:Offset alignment .............................................................................................................247Gain alignment...............................................................................................................247Signal processing of the analog inputs ...........................................................................248There are two possibilities to align the analog inputs in the optimization window: Wizard-guided under commissioning: Commissioning functions (click on theyellow triangle with the left mouse button:Caution!This wizard guided automatic alignment does not work if you bridge Ain+ withGround for the alignment!In this case, please make a manual alignment as described below.or by directly entering under optimization: Analog input4.4.8.1 Offset alignmentPerforming an offset alignment when working with the ±10V analog interface in theoptimization window under optimization: Analog input Offset [170.4].Enter the offset value for 0V input voltage.The currently entered value is shown in the status value "analog input" (optimizingwindow at the top right) (unit: 1 ≡ 10V). Enter this value directly with the same signas offset value.The status value "analogue input" shows the corrected value.4.4.8.2 Gain alignmentPerforming an offset alignment when working with the ±10V analog interface in theoptimization window under optimization: Analog input: Gain [170.2].A gain factor of 1 has been entered as default value.The currently entered value is shown in the status value “analog input” (optimizingwindow at the top right).The status value "analogue input" shows the corrected value.
