Description
Fluke 753 Process Calibrator Repair
The Fluke 753 is a documenting process calibrator — a handheld instrument that sources and measures process signals (mA, voltage, RTD, thermocouple, frequency, and pressure with a module) and documents as-found/as-left results, with HART support, to calibrate process transmitters and instruments. Its faults concentrate in the source/measure front-ends, the internal reference, and the documenting/interface electronics.
FlukeMeterRepair.com repairs and calibrates the Fluke 753 for process-instrument and commissioning teams.
Common Fluke 753 problems we fix
- Multi-signal output recalibration — the source/measure functions (mA, RTD, T/C, V, frequency) drifting, recalibrated against standards.
- Thermocouple / RTD circuit faults — a temperature input not reading correctly, repaired.
- A function dead — an input/output path failed, often after a miswire, repaired.
- Documenting / HART interface faults — the documenting or HART communication not working, restored.
- Display or battery faults.
FAQs
My 753 sources/measures wrong or a T/C input is off — fixable? Yes. Front-end 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.

Our Fluke 754 process calibrator became erratic, so we sent it in for repair. The turnaround time was exceptional. We received the meter back the next week. Very satisfied, indeed.
