Load Resistor vs. Power Supply
This is the only output from this transmitter, representing the process flow measurement, linearized and scaled according to the
configured range of the instrument. This output corresponds to the Primary Variable. HART Communication is supported on this
loop.
A guaranteed linear over-range is provided. Device malfunction can be indicated by the up-scale current of 24mA. Current
values are shown in the table below.
