Fluke 787 ProcessMeter Calibration and Repair
The Fluke 787 is a ProcessMeter — it combines a true-RMS digital multimeter with a loop calibrator, measuring and sourcing 4–20 mA (with 24 V loop power) plus full DMM functions, to troubleshoot and calibrate process loops. Its accuracy depends on the DMM measurement circuitry and the mA source/measure circuit, which is where service and calibration focus.
FlukeMeterRepair.com repairs and calibrates the Fluke 787 for process-control and instrumentation technicians.
Common Fluke 787 problems we fix
- mA source/measure out of spec — the loop source or measurement drifting, recalibrated against standards.
- DMM function faults — a multimeter function dead or inaccurate, often after an overload, repaired and recalibrated.
- Input protection blown — repaired after a miswire.
- Display faults — missing segments or dim display, repaired.
- Battery or terminal faults.
FAQs
My 787 sources the wrong mA or a function is dead — fixable? Yes. mA and DMM faults are repairable, then the meter is recalibrated so multimeter and loop functions read accurately, with a NIST-traceable certificate.
Do you calibrate both the meter and loop functions? Yes — all functions are checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.
