Adjusting R4 will cause actuator movement (for units with a Motor Positioner board) and may be
required to get actuator to 100 % position even if output is in tolerance.
16. Reposition the actuator to the 0 % of span position and take another reading.
17. If the reading is still out of line, repeat steps 12 through 16 until both zero and span readings and
positions are in line.
