Description
Fluke 714B Thermocouple Calibrator Repair
The Fluke 714B is a thermocouple calibrator — it sources and measures thermocouples (and reads/sources mV, and reads the 4–20 mA loop) across many TC types to calibrate temperature transmitters and instruments. Its accuracy depends on the thermocouple source/measure circuits, the reference-junction compensation, and the references, which is where service and calibration focus.
FlukeServiceCenter.com repairs and calibrates the Fluke 714B for temperature-calibration labs, process engineers, and instrument technicians.
Common Fluke 714B problems we fix
- Thermocouple-type source/measure faults — a TC type out of spec, recalibrated against standards.
- RTD / mV measurement faults — those functions drifting, recalibrated.
- Reference-junction (cold-junction) drift — the TC compensation reading wrong, recalibrated.
- A function dead — a source/measure path failed, often after a miswire, repaired.
- Display, terminal, or battery faults.
FAQs
My 714B reads or sources a TC type wrong — fixable? Yes. Source/measure and reference faults are repairable, then every function is recalibrated so it calibrates accurately, with a NIST-traceable certificate.
Are all TC types verified? Yes — each is checked against our temperature standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.
