3.8 Commissioning on the Bench with HHT
The 3100 Pressure Transmitter can be commissioned using an HHT
before or after installation.
Connect an HHT (HART ® HANDHELD Communicator) across
the COMM pins for HART ® communication. The TEST pin
connections can be used for connecting a multimeter to measure the
output current directly from the transmitter. Since the 3100 is a two
wire loop powered transmitter, it requires an external loop power
supply (11.9V to 45VDC) to enable HART
® communication. Any
HART ® communication via HHT (or PC based configurator) requires
a minimum 250 ~ 550 (max) ohm loop resistance.
