With analog transmitters, you must make a hardware adjustment during calibration. With HARTa (Highway- Addressable Remote Transducer) transmitters, adjustments are by remote command. These adjustments require the use of a communication tool as well as a calibrator. The Fluke 744, hereafter called “calibrator,” provides communication and calibration functions in one tool. This manual describes how to use HART mode, which is active when the calibrator is communicating over its serial HART interface to a HART transmitter. Refer to the 744 Users Manualfor safety, analog mode operating instructions, specifications, and other general information. All of the calibrator functions described in the 744 Users Manualare available and can be used with HART transmitters. The only transmitters addressed in this manual are HART transmitters. 744 HART Mode Users Guide How to Contact Fluke To contact Fluke, call: USA and Canada: 1-888-99-FLUKE (1-888-993-5853) Europe: +31 402-678-200 Japan: +81-3-3434-0181 Singapore: +65-*-276-6196 Anywhere in the world: +1-425-356-5500 Or visit us on the World Wide Web: Documenting Process Calibrator HART Mode Connecting to a HART Transmitter Connecting to a HART Transmitter To connect to and begin to communicate with a HART transmitter, refer to Figure 1 and proceed as follows: Note If you only want a communication ...
