4 Data sheet STK337 Page 4 / 5 Exploded View Operation The STK337 can be operated in the following ways: Using two buttons and zero-adjustment screw Or Operating remotely using the HART protocols -e.g. via HARTTalker and a PC with the SENSE operating programm HARTTran or -using the PDA Software SENSE offers two configuration software. They can be used the PC and PDA. Operation of push buttons The STK337 can be programmed via two buttons and zero-adjustment screw. Following parameters can be adjusted: scaling, decimal point, damping, display model, fix output current, and reset. HART-commnication via HART-protocol the possibility of setting zero and span value is given. HART-communicatin, which can run via PC, note-book, PDA, measured values and parameters become transparent and are available on every step of the signal circuit.
