*1: Handling: R=Read only, W=Read & Write, M=Method, A=Applicable for option code AL, G=Applicable for option code DG6,
D=Applicable for differential pressure transmitters. Do not change these parameters for pressure transmitters.
*2: Max three Burst Messages (Burst Message 1, Burst Message 2, Burst Message 3)
*3: The default value shows MWP (Maximum working pressure) of the capsule.
Since the working pressure limit varies according to the Model, refer to the General Specifications section in each user’s manual.
