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:
