It is recommended that the Rosemount 751 indicator be wired in a parallel
configuration when the 4-20 mA transmitter includes a test terminal.
Utilization of the test terminal is required in a parallel configuration.
Connecting the 751 indicator across the positive and negative terminals of
the 4-20 mA transmitter could impact the loop.
A parallel configuration will allow the removal of the 751 indicator without
affecting the integrity of the 4-20 mA loop. Additionally, spare 751 indicators
can be added without disrupting the loop.
