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

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).

Online Menu→4 Detailed Setup→2 Signal condition→3 PV LRV.

1.4.5 PV Damping

When online, follow the menu operation sequence shown below to access PV Damping:

Online Menu→4 Detailed Setup→2 Signal condition→4 PV Damp.

1.4.6 D/A Trim

When online, follow the menu operation sequence shown below to access D/ATrim:

Online Menu→2 Diag/Service→3 Calibration→2 D/ATrim

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.

2.4 Power Supply

Power Supply: 4.5V DC;

Power Consumption: 91.3mA (Typical value under working state)

1uA(Typical value under power-off state)

2.5 Battery

Power Supply: Three AA 1.5V alkaline batteries or rechargeable NiCad/NiMH batteries.

Battery Life: 100 hours (AAAlkaline Batteries)

80 hours (1000mA Rechargeable Batteries)

NOTE: The Communicator will shut down automatically if not used within 10 minutes.

2.6 Temperature Limit

Operating Temperature: 0°C ~+50°C

Storage Temperature: -20°C~+55°C

Note: The service lifetime of the LCD display will be shortened if the device is continuously

exposed to direct sunlight.

2.7 Liquid Crystal Display (LCD)

The LCD is an 8-line by 21 characters display that provides human-machine interface

(HMI). When the communicator is connected to a HART compatible device, the top line of

each Online Menu displays the model name and the tag of the device.

Typically, the performance of LCD displays will decrease if the ambient temperature is too

low. In order to meet your requirements for different ambient environments, a

temperature compensation circuit is embedded within the communicator, which enables

the LCD to display in good contrast and response time in colder environments.

Section 3 Keypad Instruction

3.1 On/Off Key

• Use this key to power up and power off the HART Communicator. Press this key for

at least 2 seconds.

3.2 Up Arrow Key

Use this key to move the cursor up through a menu or list of options.

3.3 Down Arrow Key

Use this key to move the cursor down through a menu or list of options.

3.4 Left Arrow/Previous Menu Key

Use this dual-function key to move the cursor to focus the left option or back to the

previous menu.

3.5 Right Arrow/Select Key

Use this dual-function to move the cursor to focus the right option or to select a menu

option.

3.6 Confirmation Key

Use this key to confirm the cursor-focused option.

Figure 5 Alphanumeric and Shift Keys

3.7 Alphanumeric & Shift Keys

Use Alphanumeric Keys to input data (Figure 5).

3.8 Using Shift Keys for Data Entry

Some menu requires data entry. Use the Up and Down Arrow Keys when available, or use

the Alphanumeric and Shift Keys to enter the alphanumeric information into the HART

Communicator.

If you press only the Alphanumeric Key with an edit menu, only the character in the center

of each key will be entered. These characters include digits from zero (0) to nine (9), the

decimal point (.), and the dash symbol (-). To enter the other characters on the keys, first

press and release the Shift Key corresponding to the position of the desired character on

the key and then press the Alphanumeric Key. Do not press the keys simultaneously. For

example, to enter the letter “R”, press the following key sequence:

Press the Shift Key again to deactivate the shift function.
