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 STK336 can be programmed via three buttons. 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.

(LCD screen showing :OPEN) 4mA Rerange With Pressure Set the present input to zero reference level, press <Z>for 2 seconds, the transmitter will output 4.000mA.(LCD screen showing: LSET) 20mA Rerange With Pressure Set the present input to span reference level, presskey for 2 seconds, the transmitter will output mA.(LCD screen showing: HEST) PV=0 Set the transmitter under the atmosphere, press <Z>and keys for 2 seconds. it can get PV=0. (LCD screen showing :PV=0) NOTE: If the PV/RANGE>0.5, it can not get PV=0. LCD screen showing PVER RESET Turn off the power, Press <Z>, then turn on the power to the transmitter, continue to press<z> for 5 seconds, if LCD screen shows OK, the transmitter get reset. NOTE: If LCD screen shows FAIL, the transmitter can not get reset (Maybe because the data has not been backup to the transmitter in factory ). MODE configure low range value <Z> choose the number or the position adjust the number or the position configure high range value <Z> choose the number or the position adjust the number or the position Configure damp time <Z> choose the number or the position adjust the number or the position Configure display mode Choose the display mode pressure, current, percent Fix output current Choose the fixed current value(3.6,4,8,12,16,20,22.8ma NOTE If there is no key pressed in 2 minutes during the setting procedure, it will return the measure mode
