Fluke 707Ex Loop Calibrator Repair

Description

Fluke 707Ex Loop Calibrator Repair

The Fluke 707Ex is an intrinsically safe loop calibrator — a hazardous-area-rated version of the 707 that sources, simulates, and measures 4–20 mA loops (with loop power) to calibrate and troubleshoot process transmitters in Ex/hazardous environments. Its accuracy depends on the mA source/measure circuitry, with intrinsic-safety integrity that must be preserved through repair.

FlukeMeterRepair.com repairs and calibrates the Fluke 707Ex for oil & gas and hazardous-area instrument teams.

Common Fluke 707Ex problems we fix

• mA source / measure out of spec — the current source or measurement drifting, recalibrated against standards.
• Quick-set knob faults — the rotary control not setting output correctly, repaired.
• Loop-power faults — the loop-supply function not driving the loop, repaired.
• Display faults — missing segments or dim display, repaired.
• Battery or terminal faults — serviced while preserving intrinsic-safety integrity.

FAQs

My 707Ex sources the wrong mA — fixable? Yes. Source/measure faults are repairable, then the calibrator is recalibrated so its mA output and measurement are accurate, with a NIST-traceable certificate and intrinsic-safety integrity preserved.

Is the source verified? Yes — source and measure are checked against our standards.

Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.
