can .accept .to .enter .the .input .and .output .values .of .the .polynomials .in .ohm .and .°C .respectively . . .
Please .remember .that .polynomial .linearisation .is .absolute . .The .output .value .is .calculated .continuously .
according .to .the .applied .input .value .and .the .function .formula . .The .max . .input .range .can .be .limited .pre-
cisely .to .the .input .range .in .which .the .polynomial .linearisation .will .be .used . .The .PRIMARY_VALUE_UNIT .
defines .the .unit .of .the .values .provided .by .the .AI_TRANSDUCER .BLOCK . .The .parameter .OUT_SCALE .in .
the .AI .block .can .scale .the .values .and .change .the .unit .to .e .g . .mV .or .ohm .
