9.4.2 Simulate Transmitter
The transmitter is adevice which can measuretemperature,electrical signalsand pressure, etc. Generating a signal
accordingtothemeasurementimposed.
The calibrator can simulate a transmitter.It can measure RTDs, thermocouples, frequency, volts, mA, ohms and
pressure(whenthepressuremoduleisconnected),andoutputmAandvoltssignal.
Before
startingthetransmittersimulation,youshouldensuretheexternaldeviceisavailable.
TakingtheexampleofanRTDTemperatureTransmitter(T/I),proceedasfollows:
1. Selecttheinputandoutputquantitiesofthetransmitter.
2. Entertheinputandoutputspansofthetransmitter.
3. Startrunningthesimulatetransmitter.
On
theQuantitypage,selectmA&24VfromtheoutputquantitylistandselectRTDfrominputquantitylist.Inaddition, 
choosethecorrectsensortype,temperatureunitandconnectionwiresfortheRTD(asshowninFigure9.2).
OntheRangepage,settheinputrange0to200℃ andtheoutput
range4to20mA.Sometimes,itisnecessarytoset
thetransferfunction:Linear/Squareroot(asshowninFigure9.3).
Press Enter or Start to start running the transmitter simulation. The simulation will pause when the transmitter is
working.Whenthesimulationispaused,boththeinputandoutputof
thetransmitterwillalsopause
