The 754 Documenting Process Calibrator uses an industry-wide communication protocol called HART, an acronym for Highway Addressable Remote Transducer. It can connect with most, but not all, “Smart” temperature and pressure devices. This allows the 754 to capture data such as serial numbers and IDs.
The 754 can communicate with HART in 2 ways. The unit ships defaulted in the HART port mode.
1. The default mode is accessed from the top side port connection using a specialize cable.
2. The second mode is accessed from the mA jacks on the bottom of the unit.
3. Once the 754 is turned on press setup and scroll down to change the ports.
4. Press the up or down to switch from the HART port and mA Jack and press enter. Press F4 (Done) to finalize option.
