I work on a electronic positioner transmitter 4211 at the field.I connect my multimeter in series to get the current output then I calibrate it to 4ma in 0% of position of the valve and 20ma in 100% position of the valve.My problem is in the field I get the correct output current based on my multimeter but in the dcs they only receive 40% in a output 20ma of this positioner.Then I try to simulate in this analog card and they receive the equivalent percent on the value that I simulated.Is ther any possibility to reset the zero and span of this positioner 4211 fisher.And what other possibility I can do to fixed this.This is my email add ( landicho_randy@yahoo.com )
