Oper ating level and Parameter level are set to none Both outputs current and voltage are always available at the same time However the output that has not been acti vated in the setup program or by the default setting only has an accuracy of approximately 2 of full scale The frequency output will not be operated as long as the setup plug remains plugged in 14 6 PC setup program Operation on the transmitter permits the alteration of only a few pa rameters Using the PC setup program which is available as an ex tra code all parameters of the transmitter can be conveniently al tered Through the setup interface the transmitter and the PC are connected to each other via the PC interface with TTL RS232 con verter and adapter Configurable parameters TAG number 10 characters analog input Sensor type connection circuit 2 3 4 wire external or constant cold junction customized linearization range limits start and end output signal current voltage frequency rising falling digital filter response to probe break short circuit recalibration fine calibration instrument calibration limit value differential of limit comparators file info text Additional benefits of the PC setup program manage several different settings one setting for a number of transmitters print out setting for documentation operation can be switched to GMA standard d The frequency output will not be

Zero push buttons The momentary value will be produced via the output The value is accepted by simultaneously pressing Span and Zero Span and Zero can always be used to set the limit values How ever the limit query can only be activated through the PC setup program which is available as an extra code There you can also define the limits for the differential Two functions are available for limit monitoring With the help of the setup program you can decide which one to use Function Ik7 E O Upper E differential 9 Lower 2 differential amp A O Limit value Measurement Function Ik8 Upper differential Lower differential Transistor Limit value Measurement 10 4 Functions and operation Fine calibration zero point and full scale Fine calibration can be used to adjust the zero point and the slope of the output signal Here too the Span and Zero push buttons are available for altering the appropriate value or for accepting it by simultaneously pressing both push buttons The converted value is produced at the output At zero point this should correspond to the output signal 0 at full scale to the out put signal 100 The formula for calculating the new converted value is output converted value measurement input valuegcaieg X full scale zero point 11 4 Functions and operation Teach in The Teach in p
