Description
Fluke 726 Multifunction Calibrator Repair
The Fluke 726 is a precision multifunction process calibrator that sources and measures the full range of process signals (mA, volts, RTD, thermocouple, frequency, ohms, and pressure via a module) with high accuracy and documenting features. Its accuracy depends on the multiple source/measure circuits, the references, and the reference-junction compensation, which is where service and calibration focus.
FlukeServiceCenter.com repairs and calibrates the Fluke 726 for temperature-calibration labs, pharmaceutical QA, and process-instrument technicians.
Common Fluke 726 problems we fix
- Reference-junction (cold-junction) drift — the TC compensation reading wrong, recalibrated against standards.
- RTD / thermocouple source/measure faults — a temperature function out of spec, recalibrated.
- Pressure-module interface faults — a connected pressure module not reading, repaired.
- Display or terminal faults — repaired.
- Battery faults.
FAQs
A function on my 726 reads or sources wrong — fixable? Yes. Source/measure faults are repairable, then every function is recalibrated so it calibrates your instruments accurately, 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.
