The Fluke 744 process calibrator is multifunctional; calibrate temperature, pressure, voltage, current, resistance and frequency. It measures and sources allowing for troubleshooting and calibration all with one rugged tool. The easy-to-follow, menu-driven display guides you through any task. Programmable calibration routines enable you to create and run automated as-found/as-left procedures to ensure fast, consistent calibrations.

Fluke 744 process calibrators support your ISO-9000 or regulatory standards by capturing your calibration results, eliminating pen and paper in the field. The RS-232 interface transfers results to a PC eliminating manual transcription. The 744 supports popular instrumentation management software from Honeywell Loveland, Cornerstone, Yokogawa, Prime Technologies, On-Time Support and others. Createprocedures, instructions and action lists to deliver fast, easy documentation.

The Fluke 744 process calibrator is small enough to fit easily into a tool bag and use in tight spaces. The overmolded urethane case stands up to rough handling in industrial environments. Soft keys provide one-touch access to enhanced functions such as task lists, automated procedures, scaling, min/max, stepping and ramping and review memory.

The Fluke 744 combines HART communication capability with the documenting process calibrators to deliver an integrated communicating calibrator. The integrated HART communication functions permit monitoring, controlling and calibrating HART instrumentation. It can also handle fast pulsed RTD transmitters and PLCs with pulses as short as 1 ms.

The Fluke 744 offers the most complete HART implementation of any process calibrator. The Fluke 744 requires no external box or second tool for everyday HART calibration and maintenance. It supports popular models of HART transmitters, with more device-specific command support than any other HART field calibrator. The 744 also full complies with the Data Link layer of the HART protocol, inlcuding multiple masters, burst mode and multi-drop configurations.

The Fluke 744 ships complete with Type TL224 industrial test leads (two sets), AC220 test clips (2 sets), TP220 Test probes (1 set), battery pack, battery charger, serial port cable, HART communications cable, DPC/TRACK sample with free PC communication utility software, instruction manual and NIST-traceable calibration report and data.
