Description
Fluke 787 ProcessMeter 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.

My Fluke 787 processmeter stopped reading both voltages and ohms accurately. Sent in for repair, and they did an excellent job with correspondence, repair explanation, and billing. Made it easy to get my meter repaired and returned without a lot of effort on my side.
