Fig.6-42 Relation curve between analog output and zero offset
 Note
The output gain and zero offset correction function codes will real time affect the analog output during the
change.
P10.29 and P10.30 are used for correcting the zero offset of analog inputs AI1 and AI2.
Take AI1as an example to introduce zero offset correction.
AI1 is used as voltage type signal, when the input signal is 0V, observe AI1 value P01.20, if P01.20 is
non-zero value at this time, it indicates that AI1 has zero offset, you need to enter the value which has
equal absolute value but opposite sign with P01.20 in P10.29. If P01.20 = 0.01V, then set P10.29 =
-0.01V.
