3.10 Shop Commissioning using 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.
