why we use 250 ohms across HART CALIBRATOR DURING
CALIBRATION OF TRANSMITTER

Answer / xyz
If we do not use 250 ohm resistance then our HART calibrator
shall connect directly to power source, hence it won't be
part of our transmitter loop.

WE USE 250 OHMS RESISTANCE ACROSS HART CALIBRATOR DURING
CALIBRATION OF TRANSMITTER DUE TO LOAD GIVEN TO TRANSMITTER
FOR COMMUNICATION PURPOSE

I think 250 ohm use for drop the crrunt of circuit .If I use above the 250 ohm i can't get sufficient output crrunt.one thinks more that if you increase or decrease the ohm as well as output crrunt will be increase dearead . that's why i can't exceeds resistance value

dear sir we have insatlled positioner model no.sipart PS2 make Siemens at our control valves . now problem is if we want to increase the response of valve opening speedy /fast. what parameters do we change for positioner ? any idea. please guide us.
