4.Turnthefeedbackpotentiometershaft(6)with
a screw driver until you read 3.7 - 3.9 mA on the meter.
5.Adjustthetrimpotentiometer(7)markedzero
so that the meter reads 4mA.
6.Setthevalve/actuatortotheopenposition(20mA).
7.Adjustthetrimpotentiometer(8)marked
span until the meter reads 20mA.
8.Re-checkthezeroposition(4mA)and
 makeneadjustmentsifnecessary.
A very basic calibration can be accomplished
without a meter, using the two LED’s.
