Communicator or converter connection to the transmitter’s terminals
In order to enable local communication by connecting a communicator or converter to the transmitter’s
terminals, make sure that the resistance Ro from the transmitter’s terminals to the power supply source lies
within the range of 240÷1100 If so, connect the communicator or converter to the terminals <+> <->
as shown in Fig. 2b.

transmitter terminals in case of the resistance in current loop is higher than 240Ω.
To measure the transmitter current without
disconnecting the measuring loop, connect
a milliammeter to control terminals <TEST->
and <TEST+>.
