The switch action values are recorded only when the output item is pressure.
Only a pair of action values is recorded, including the switch state (on to off/off to on) when
triggered and pressure value.
Press and select "Reset", to clear the action values.
Press and select "Switch Setup", to switch between mechanical switch, NPN switch and PNP
switch.
3.3.3 HART Communication
The calibrator supports HART bus communication, uses simplified DD files, and provides setting
maintenance and calibration for general and common parameters of HART pressure transmitters.
Before using the calibrator to operate the transmitter, please refer to the user manual of transmitter. If
you need full-featured HART operation, please refer to Chapter VII "HART communicator".
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.
1. Search and connection
Under the main operation interface, open the electrical measurement area for display. Select
in mode switching to enable the HART function. The calibrator will automatically switch to
power configuration selected previously (connection mode of internal power supply and internal
resistance by default), and search for the address "0". When a HART device is found, the
