Description
Fluke 744 Process Calibrator Repair
The Fluke 744 is a documenting process calibrator with HART communication — a handheld instrument that sources and measures process signals (mA, voltage, RTD, thermocouple, frequency, and pressure with a module), communicates with HART transmitters, and documents results, to calibrate and configure process instruments. Its faults concentrate in the source/measure front-ends, the HART/communication interface, the internal reference, and the documenting electronics.
FlukeMeterRepair.com repairs and calibrates the Fluke 744 for process-instrument and commissioning teams.
Common Fluke 744 problems we fix
- Multi-signal output recalibration — the source/measure functions (mA, RTD, T/C, V, frequency) drifting, recalibrated against standards.
- HART-communication faults — the HART interface not communicating with transmitters, repaired.
- A function dead — an input/output path failed, often after a miswire, repaired.
- Pressure-module interface faults — the module input not reading, repaired.
- Display or battery faults.
FAQs
My 744 sources wrong or HART won’t connect — fixable? Yes. Front-end, HART, and reference faults are repairable, then every function is recalibrated against our standards so the transmitters you calibrate are trustworthy, with a NIST-traceable certificate.
Are all functions verified? Yes — each source/measure function is checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.

We have had several Fluke 744 process calibrators repaired by June Company as well as the newer Fluke 754 process calibrators. They did a fantastic job on both the repairs and calibrations, as well as ISO-9001 certifications. Excellent job.
