Trim potentiometer Po can be used to adjust a current of 4 mA to
potentiometer values of 0 ... 15% of the total range.
•
Trim potentiometer Po can be used to adjust a current of 20 mA to
potentiometer values of 90 ... 100% of the total range.
The smallest available potentiometer range, in which 4 ... 20 mA are deliv-
ered, is hence 15 ... 90% of the potentiometer’s resistance range.

1. Move the machine to the start position.
2. Turn potentiometer Po

until start value 4 mA is measured.
3. Move the machine to the end position.
4. Turn potentiometer Pe

until end value 20 mA is measured.
The steps 1 to 4 are to be repeated until the values are counterbalanced
(iterative alignment).
