Fig. 2.
In case of transmitter calibration outside danger zone is possible communicator connecting to
<SIGNAL+> and <TEST+> terminals. Transmitter is furnished in communication resistor (R
D
= 240Ω),
closed with jumper at <SIGNAL-> and <TEST-> terminals installed by manufacturer. R
D
resistor can be
use then, when it is necessary to communicate with transmitter from its terminals and the load resistance
(Ro) in current loop is lover then 250Ω. Than <SIGNAL-> and <TEST-> terminals have to be open.
