Output Bias with different values different locations

The processing of Output Bias with different values in different locations,Due to the problem of mechanical structure

How should I deal with this problem?

The bias can be changed on-the-fly every millisecond if necessary. We have had to do this for a few applications.
You need to write a user program that changes the bias as a function of position.
Another option is to use the curve tool and use the position to index into the curve tool. There are crv_??? functions. What you want to do is use CRV_INTERP_Y() function.
