Section 1 Operation Instruction
1.1 Brief Introduction
H375A HART Hand Held Communicator is a hand held interface based on HART protocol,
which could perform configuration, management, maintenance and adjustment to all
HART
compatible instruments (Figure 1).
Figure 1 H375A HART Hand Held Communicator
H375A HART Hand Held Communicator can be easily connected into 4~20mA loop, to
achieve the configuration of instrument parameters (upper limit and lower limit etc.), the
reading of instrument variables, as well as the diagnosis and maintenance of the
instrument. This Communicator could support not only the first main device (HART
multiplexer etc.), but also the point-to-point and multipoint HART communication modes.
1.2 Communicator Connections
This HART Communicator can interface with an instrument from the control room, the
instrument site, or any wiring termination point in the loop through the back connection
panel (Figure 2).
