Until now, instrument technicians have had to use two separate units to calibrate and maintain HART (Highway Addressable Remote Transducer) transmitters. The Fluke 744 combines these functions into a single unit. The 744 comes with the most complete HART implementation of any process calibrator, and is upgradable to support changes in the HART standard.
The 744 Process Calibrator provides unmatched functionality for industrial applications, including sourcing and measurement, creation and execution of automated procedures, automated results capturing, transmitter mode, bar code data entry, serial interface, data logging and HART communication functions. It handles fast-pulse RTD transmitters and PLCs with pulses as short as 1 mS. The 744 is powered by a nickel metal hydride (NiMH) battery with 3500 mA hour capacity and ‘gas gauge.'
The integrated HART communication functions enable the user to monitor, control and calibrate HART instrumentation. The 744 can be used to "query" other HART devices to determine their type, manufacturer, model and serial numbers. The 744 fully complies with the Data Link Layer of the HART protocol, addressing multiple masters, burst mode and multi-drop configurations. Moreover, the 744's 2 MB of memory provides device-specific support for a wide range of popular transmitters.
The Fluke 744, based on the Fluke 743B Process Calibrator, is the most rugged, reliable multifunction field calibrator available. The unit ships complete with a battery charger, a serial port connection cable, a HART communication cable, two sets of TL24 industrial test leads, two sets of AC20 test clips and one set of TP 20 test probes. Also included is a complimentary Windows-compatible software utility that allows easy porting of recorded data to a desktop PC.
The 744 Process Calibrators are backed by a three-year warranty of service and support by Fluke Corporation, a member of the HART Communication Foundation. The 744 is available from Fluke distributors and representatives worldwide.
