7.6 Current Measurement/Loop Transmitter mA Measurement
Loop transmitter mA measurement provides 24V loop power, and
also can measure the current value in the loop. In this mode As Fig （
7.4 , the circuit power has series resistor greater than 250Ω, which ）
can be compatible with HART devices without using external resistor.
