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.
