3.10 Shop Commissioning using HHT
The 3200 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 3200 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.
