Thoughts on the difference between the calibration and re-ranging of a pressure transmitter. Take a rosemount 3051 smart transmitter recently calibrated to measure flow 0-100m3/hr with sq/rt being applied at the trip amp.
Now, a few weeks later, the trip amp is removed from the loop, the range is changed to 0-200m3/hr and sq/rt is applied in the transmitter head.
The question is: should the transmitter now have a function test conducted on it such as having its calibration checked?
