Note 1: See subsection 10.2, “Model and Suffix Codes,” for details.
Note 2: Applicable for HART communication type. Set the switches as shown in the figure above to set the burn-out direction and write
protection. The Burnout switch is set to the H side for delivery (unless option code /C1 or /C2 is specified in the order), and the
hardware write protection switch is set to E side. The setting of the switches can be confirmed via communication. An external
zero adjustment screw can only be enabled by communication. To enabled the screw, set a parameter before activating the
hardware write protect function. See each communicaion manual.
Note 3: An external zero point adjustment had been disabled by factory setting.
