Communicator Attached to a Network 6.6
In the example that follows, the calibrator connects directly
to a network. There must be a 250 Ω resistor in series with
the loop power supply and the HART® device.
Figure 6-3
CH2 function is set to None. HART® function is enabled and
250 Ω resistor is set to Off.
Use of Test Connections 6.7
Use the test connection with a HART® transmitter. Use CH1
to measure current and CH2 to communicate with the
HART® device. CH2 must be set to None, and CH1 must be
placed into current measure mode. There must be an
external HART® resistor in the loop.
