In a loop calibration procedure, which action confirms the system's performance after transmitter calibration?

• A. Document results
• B. Verify loop response
• C. Simulate signal
• D. Verify wiring

Answer: (B)

Verifying loop response is the action that confirms the system’s performance after transmitter calibration. After the transmitter is calibrated, you test how the entire control loop reacts to an input change by observing the actual dynamic behavior: does the process variable move toward the setpoint as expected, within the anticipated time, and with acceptable stability (limited overshoot, no sustained oscillations)? This step checks the end-to-end interaction of sensor, transmitter, controller, final control element, and the process, ensuring the loop behaves as designed in real operation. While documenting results, simulating signals, or checking wiring are important tasks, they do not by themselves confirm how the loop will perform in service.
