"MasterPiece 200/1 Error in Linearization for DSAX 110 and DSAI 133" resolves the following:
A description of this resolution:
- See SOLUTION and CORRECTION
SOLUTION
The linearization can be done with PC elements instead:
Example.
Set RANGE_MIN to 0 and RANGE_MAX to 1.00
Extract the Square-root using the SQRT element.
Scale the value using the K input of the same element.
If desired, present the value for MV800/1 using a "Calculated Analog In" database element.
CORRECTION
The error has been corrected in MasterPiece 200/1 *3.0/7, software QMP220 SW*5.0/7, QMP240 SW*5.0/7, QMP260 SW*5.0/7, QMP280 SW*5.0/7, QAC280 SW*5.1/1

"MasterPiece 200/1 Error in Linearization for DSAX 110 and DSAI 133" resolves the following:
- Error in Linearization for DSAX 110 and DSAI 133
The function LINEARIZATION, property LIN_CODE (terminal 9) of database element AI signal does not function properly for DSAX 110 and DSAI 133.
Normally, the error is a small scaling error over the full range.
If LINEARIZATION is used in combination with a "living zero range" (for example CONV_PAR = 4..20 mA) then the scaling is done as if the was no "living zero range" (scaling starts from zero). The error does not exist for DSAI 133 running in the normal AI mode under the AI-board element, only under the AX Redundant element.
