Fluke 744 Documenting Process Calibrator Repair
The Fluke 744 is a documenting process calibrator (DPC) — it sources and measures the signals process instruments use (mA, V, RTD, thermocouple, frequency, pressure with a module) and documents as-found/as-left results for calibration records. As a precision source-and-measure instrument, its faults concentrate in the reference, the source/measure circuitry, and the input/output functions.
June Company repairs and calibrates the Fluke 744 for instrument-calibration technicians and process teams.
Common Fluke 744 problems we fix
- Source or measure out of spec — reference or source/measure drift across functions (mA, V, RTD, T/C), recalibrated against standards.
- A function dead — a specific source or measure path failed, often after a miswire, repaired.
- Input protection blown — fuse/protection repair.
- HART or pressure-module faults — the communication or module interface, restored.
- Display, battery, or documentation faults.
FAQs
My 744 source/measure drifted — fixable? Yes. Reference and source/measure faults are repairable, then recalibrated across every function so as-found/as-left documentation is trustworthy, with a NIST-traceable certificate.
Do you calibrate all functions? Yes — mA, voltage, RTD, thermocouple, and frequency are checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
