Communications Setup and Selection For all Main screen operation modes, except mA Measure with 24V or Volts Measure, the operation mode is set to mA Measure when you enter the HART Comm. Menu. The operation mode remains the same as the main screen when it is Measure with 24V. If Volts Measure was selected from the Main menu, the menu defaults to communicator mode only and the 250 Ω resistor selection shows n/a. The 250 Ω resistor selection cannot be edited in communicator mode. The mode and resistor will change from the last selections made in the HART Comm. Menu when you exit the menu. The mode and 250 Ω resistor settings must correspond to how the test leads are connected before you connect. See Figure 23. Figure 23. HART Comm. Menu Screen Select a function from the menu and push the selection knob to do the function. Push  to disconnect from HART mode and go to the function home screen without action. An error shows and no action is taken if the measured input is out of range, OL or -OL. 250Ω Resistor and HART CONNECT functions are described in subsequent sections. Precision Loop Calibrator HART Device Communication Mode The Mode function from the HART. Comm. Menu lets you select what mode to work in. See Figure 24. Figure 24. Mode Selection Screen Use the selection knob to choose the mode: • mA Measure- The Product is in circuit and loop power is supplied externally. • mA Measure with 24V- The Product is in circuit and the loop power is supplied by the Product. • Communicator Only- The Product is across the circuit and the loop power is supplied externally. The 250 Ω resistor selection defaults to n/a (not applicable). • mA Src HART Valve- to source mA signals and communicate HART to connect and communicate with control valves. • mA Sim HART Valve- to simulate mA signals and communicate HART to connect and communicate with control valves with control system 24 V loop power. 21
