Dear Madhava, When the projetct start client said that he used only 2wire insstrument, and as per client requrement we are use ET200S, now when complete the drawings and sent to the client for approval at that time they replied some of the instruments are to changed 2wire to 4wire. As before i am never making wiring for 4wire. Also i am confused in suplly to the instrument....its deficult for me
