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.

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
