Connection
For using loop power, connect the 4~20mA signal with DC power
supply so that the current can flow from + to - on the input terminals
as shown above. No additional resistor connection is required at this
time. If a transmitter with a separate output signal, then connect
directly to the same polarity.
After connecting external sensors, RN400 MUST be used the UA-
CALIBRATOR software to set the Minimum and Maximum values on
software( See section 3.3.).
