Section 1 Operation Instruction
1.1 Brief Introduction
The HK-H375A HART Hand Held Communicator is a hand held interface based on HART
protocol, which can perform configuration, management, maintenance and adjustment to
all HART
compatible instruments (Figure 1).
Figure 1 HK-H375A HART Hand Held Communicator
The HK-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 supports not only the HART main device (HART
multiplexer etc.), but also the peer-to-peer and multidrop 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 clips and cable
(which are the accessory of the communicator) (Figure 2).
