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 HARTcompatible 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).
Figure 2 Clips and Cable

6
This HART Communicator could be connected in parallel with a HART instrument, or with
load resistor. All connections are non-polarized (Figure 3).
Figure 3 Communicator Connections
NOTE: For the HART Communicator to function properly, a minimum of 250 ohms
resistance must be present in the loop. The HART Communicator does not measure loop
current directly.
1.3 Power up
First make sure that batteries have been installed appropriately in the Communicator.
Then press the On/Off Key to power up the Communicator（once again for shut
down）. Approximately for 5 seconds after the startup, the Communicator will automatically
poll the HART device (polling address 0) in the 4~20mA loop. If a device is not found, the
Communicator will display the message “No device found at address 0, Poll?” If a device
is found, the Communicator will display the Online Menu (Figure 4).

NOTE: D/A Trim is usually done before the HART instruments leaves the factory or in the
periodic calibration of the instrument. Only qualified personnel should be perform this
operation, otherwise any inappropriate operation may increase the output error of the
HART instruments.
1.4.7 Zero Trim
When online, follow the menu operation sequence shown below to access Zero Trim:
Online Menu→2 Diag/Service→3 Calibration→3 Sensor Trim→1 Zero Trim
NOTE: Zero Trim can negate the zero error of the instrument caused by installation
method. Generally speaking, it is usually done at the first installation of the HART
instrument or during the scheduled calibration of the instrument. Only qualified personnel
should be designated to perform this operation, otherwise any inappropriate operation
may increase the output error of the HART instrument.

4.7 Other Tasks
4.7.1 Automatic Polling
When online, the HK-H375A Hand Held Communicator will poll automatically the online
devices at address 0. If not connected to a device, the Communicator will display the
message “No device found at address 0, Poll?” Select “YES”, then the Communicator will
poll automatically all the devices connected from address1 to address 15.
When several devices are connected in the same loop, each device must be assigned a
unique address. If two devices share the same address, the communicator will not be able
to find the devices. At this point, the devices will need to be connected separately to
correct the polling address. HART Protocol defines the communication mode of
connecting several devices in the same loop as multidrop mode. Under multidrop mode,
the current in the loop will not be current signal of 4~20mA standard, but the sum of the
output current from all the devices.
4.7.2 Download
Follow the menu operation sequence shown below to access Download:
Main Menu→2 Download.
This function is designed for customers to easily update the DD in the HART
Communicator. We will update the DD periodically. Please do not hesitate to contact with
us for the relevant technical support.
This function is associated with the special PC software, downloading the target file into
the HART Communicator at the default baud rate 38400bit/s.
When the interface displays “Download target file”, select “OK”, then the download starts
and the Communicator will display “Please wait a moment...” When the download finished,
it will go back to the Main Menu.
Note: Please do not use this function without proper PC software and guidance from the
manufacture,
4.7.3 Battery
Follow the menu operation sequence shown below to access the Battery:
Main Menu→3 Battery.
This function will check the remaining battery capacity and display it in percent (%). When
the battery capacity is too low, please change the batteries at once to avoid influence on
the normal use of the Communicator.

16
4.7.4 Polling
Follow the menu operation sequence shown below to access Polling:
Main Menu→4 Polling.
When several devices are connected in the same loop (multidrop), you can achieve the
communication with the required device by polling (Figure 13).
Figure 13 Polling Menu
Item 1 is Single Polling, you can select any address between 0 and 15 to communicate；
Item 2, 3, and 4 is group polling; address 0~15 has been divided into three groups.
When a device is found by group polling, the Online Menu will display and communicate
with the lowest address found. To communicate with higher address devices, single
polling is necessary.
