5. Adjust the potentiometer by turning its shaft with a flat blade
screwdriver so that the output current reaches a minimum
value.
6. Turn backwards until the current value regularly increases,
then turn backwards again and stop as soon as the minimum
value determined above is reached.
7. Tighten back the potentiometer pinion blocking screw.
The potentiometer is then positioned at the very beginning of
its track.
8. Use the TAM adjustment screw marked 0/4 mA to adjust the
current to a value as close to 4 mA as possible.
9. Drive the actuator to the position corresponding to 20 mA
(open position).
10. Turn the screw marked 20 mA so that it reads exactly 20 mA
on the milli-amp meter.
11. Come back to the closed position.
12. Check that, for the 0% position, the signal current shows a
repeatable value that is close to 4 mA.
