How can incorrect calibration of a pressure transmitter be identified?
A. By comparing the transmitter reading to a known reference value
B. By checking the calibration date on the transmitter
C. By monitoring the process and looking for deviations from expected values
D. None of the above

Explanation: Incorrect calibration of a pressure transmitter can be identified by comparing the transmitter reading to a known reference value, such as a reference gauge or pressure standard. Any discrepancies between the transmitter reading and the reference value may indicate the need for recalibration.
