Z axis.
Ensure the sensor is in Position 0 (see Figure 7 ). Select the Z axis and record the X and Y errors
due to Z (Xz, Yz). Rotate the sensor along the Z axis to end up in Position 3 (see Figure 14 ). The errors
obtained will be, Xz ’ and Yz ’. The target value for X z and Yz will be calculated as (Xz ’ -Xz)/2 and (Yz ’ -Yz)/2.
Adjust the potentiometers X->Z and Y->Z ( Figure 15 ).
