So, how is the initialization of instruments (transmitters) carried out? We know that field measurement instruments operate with low voltages. When performing maintenance online, should we work while the equipment is powered on or powered off? During initialization, should the operator panel be connected directly, or after the wires are disconnected? What are the specific steps to follow after connecting the handheld controller? Is there any expert who can give us a clear and detailed explanation? Thank you so much! The reason why newcomers like us have so many questions is that there is a lot we don’t understand; as a result, the questions we ask sometimes turn into jokes, which is truly embarrassing for those with more experience! What I actually want to say is that after swapping some instruments and meters, if initialization is required, what should be taken into consideration and what are the steps involved. Also, which instruments and meters need to be initialized when in use? I hope the experienced teachers can give me more guidance and criticism! I will definitely listen carefully! -------The transmitter initialization mentioned earlier actually occurred when I encountered a transmitter whose readings were inaccurate; I suggested that the electrical and instrumentation technicians replace the transmitter or perform maintenance on it. They told me that this would be complicated and that initialization would be necessary. That’s why I asked my previous question.
