12-4d. To adjust for 0.000 volts:
1) Monitor the output of axis 1.
2) Using the adjusting tool, adjust the zero control for axis 1 (Figure 13) for 0.000
volts output.

12-4e. Move the target through a known displacement to its maximum range (9 mils
standard) and adjust the axis 1 gain control (Figure 14) for the desired output (9 volts
standard).
12-4f. Return the target to the null position and check the output. You most likely will
not see 0.000 volts output unless you have a very good dimensional standard and very
stable fixturing located in a controlled environment. When measuring at sub micro inch
levels, the world becomes rubber, and your fixturing may have expanded or contracted
and you won’t see 0.000V again.
12-4f1. All things considered, after returning the target to the null position, output should
be 0V (±10mV or less). If the output at null exceeds this, repeat the process. Calibration
should not take more than two iterations.
12-4g. Repeat the process for axis 2, monitoring the output at pin 6.
12-4h. The system is ready to use.
