the same time. the real-time leakage amount = the starting pressure - the real-time pressure.
5) Record the pressure at the end of the test time as the end pressure.
6) The entire leak detection process ends, and the final leakage amount = the starting pressure -
the ending pressure.
The entire process is shown in stages in the leak detection curve diagram at the bottom of the
screen.
7. HART Communication
The calibrator provides full HART communicator function. Using the original HART DD file, the
calibrator can be used to complete almost all HART pressure device maintenance and debugging,
including parameter modification, fault diagnosis, daily maintenance and calibration, etc. Because the
operation of communicator on the HART device depends on the DD file, the operation methods of
different HART devices are quite different, so refer to the operation instructions of the HART device
before using the communicator function.
Note: During communication with a HART device, the calibrator acts as a master station all the time.
To avoid damaging the control system, you must separate the HART device from the control system
before connecting the calibrator to HART device.
