Let’s take a look at how to choose this

For a certain pressure transmitter, the main control indication fluctuates significantly frequently; possible reasons include ( ). A. Pressure conduit blockage B. Transmitter connector leakage C. Safety barrier failure D. Transmitter module failure
9. The task that must be carried out after replacing the HART transmitter is ( ). A. Change device address B. Change device tag number C. Change range D. Redownload
For the first question, both of the first two options are incorrect; it should be D.
The second question should be about changing the range, C. The transmitter is only located outdoors, so it can be replaced simply by turning off the power.
I think it should all be A, B, C, D. . . . . . . . . . . . . . .
Both C and D are possible; D is certain. If it’s a single-choice question, choose D
For a certain pressure transmitter, the main control indication fluctuates significantly frequently; the possible cause is (d). A. Pressure guide tube blockage B. Transmitter connector leakage C. Safety barrier failure D. Transmitter module failure
For a certain pressure transmitter, the main control indication fluctuates significantly frequently; the possible cause is (d). D. Transmitter module failure
Personally, I think for both questions, C should be chosen
