2.5 Intelligent HART Calibration（ADT673 only）

The calibrator supports HART communication, uses a simplified DD file to provide the setting, maintenance and
calibration of common parameters for HART pressure transmitters. It is recommended to refer to the instruction manual
of the transmitter before using the calibrator to operate the transmitter. If you need full-featured HART operation, please
refer to Chapter 8 "HART Communicator".

Note: The calibrator always acts as the master station during the communication with the HART device. Therefore,
in order to avoid harm to the control system, the HART device must be separated from the control system before using
the calibrator to connect to the HART device.

1. Search and Connection

◆ Turn on the electrical signal measurement area display in the main operation interface, select mode to

start the HART function, and the calibrator will automatically switch to the power supply configuration selected
by the last HART measurement (the default connection mode uses internal resistance with internal power
supply), and to search the "0" Address. After searching for the HART device, it will automatically connect and
display its value.

◆ Press to start search，or click the HART measurement channel screen when the HART device is not

connected to enter the HART power supply configuration interface. The connection method provided by the
calibrator is as follows:

item;

◆ In the main operation page, switch the electrical measurement option to other measurement modes (such as
current measurement) to exit the HART connection, and at the same time, switch the HART measurement icon
in the status bar to the corresponding icon (such as current measurement);

◆ When the HART communication fails in the main operation page, it will automatically search for new devices
again;

◆ In a test involving HART, if HART is offline, the test prompts HART is offline.

3. Process Value

◆ In main operation page, Hart as electrical item, press to enter the process value，the main variable
PV, output current AO, percentage, second variable, third variable and loop current can be displayed at the
same time. The units of the second and third variables are determined by different device;

measurement is stable, press the Acquire key to directly obtain the standard value or directly press the
number key to manually input the value to be adjusted;
Note: Some transmitters do not need to input the adjustment value, the transmitter automatically uses the
upper and lower limits of the range (the lower limit of the range corresponds to the low point adjustment
value, and the upper limit of the range corresponds to the high point adjustment value) as the adjustment
value. In this case, any value can be input ；

2) Execute the trim (Trim) command. After successful, the PV value will change according to the executed trim
point value.

◆ Upper limit adjustment

The type of pressure switch, view support information according to

calibrator’s model

(1) Select application in the function menu and enter the leak test;
(2) Set the wait time

1) Connect to external pressure source: the wait time will count down.

2) Enter the test time after the wait time is over.
(3) Set test time

After entering the test time, the countdown starts and the test is carried out, the test stops when the timer
reaches 0;

(4) Pressure type

Switch between gauge pressure/differential pressure.

2. Carry out

(1) Connect air circuit

1) Connect the device to the air circuit;

2) Press the Start icon on the right of the screen to start the test. Apply pressure to the leak test point;

3) The wait time will count down and record the real-time pressure as the initial pressure when the time is over;

4) Start the test, count down the test time, and start calculating the real-time leakage at the same time, real­time leakage = initial pressure - real-time pressure;

5) Record the pressure at the end of the test time as the end pressure;

6) The entire leak test process finishes, and the final leakage = initial pressure - end pressure;

(2) The whole process will be shown in stages in the leak test curve at the bottom of the screen;

7.3 PSV test

Click on the button in the function menu to enter the PSV test function. The PSV test is used to test the

54

opening pressure of the safety valve. In order to ensure the accuracy of the opening pressure test, the pressure
gauge/calibrator will automatically enter high-speed reading mode and continuous recording of pressure data ten times
per second, real-time recording of the maximum pressure, and draw the real-time pressure data curve to visually show
the trend of pressure changes.

8 .HART communicator (ADT673 only)

Click on the button in the function menu page to enter the HART communicator function. The HART
communicator uses the native HART DD file. The calibrator can be used to complete the maintenance and
commissioning of almost all HART pressure device, including parameter modification, fault diagnosis, and daily
maintenance and calibration, etc. Concerning that the operation of the communicator on the HART device depends on
the DD file, the operation varies a lot between different HART devices, so please refer to the manual of the HART device
before using the function.

Note: The calibrator always acts as the master station during the communication with the HART device.

Therefore, in order to avoid harm to the control system, the HART device must be separated from the control
system before using the calibrator to connect to the HART device.

8.1 HART connection and search

Refer to Para.2.5 HART communication connection and search.

8.2 HART communicator operation

Read the parameters in HART and modify them, the root directory shows items1~4, depends on the HART device,

The parameters that have been modified but not written into HART are highlighted in yellow in the list, click on
to complete the writing to the HART device;

56

For some of the parameters, enter the page and click on at the right of the screen to view the instruction
information.

Click on the and at the right of the screen to view the communicate status and device status respectively.
Enter it and the vacant circle on the right of the list indicates that it is normal, otherwise it means that the item is
abnormal.
