Fluke 87 III Multimeter Repair and Calibration
The Fluke 87 III is a rugged industrial true-RMS digital multimeter — a precision handheld measuring AC/DC voltage, current, resistance, frequency, capacitance, and temperature for demanding electrical and industrial work. Its accuracy depends on the input/measurement circuitry, so that’s where repair and calibration focus.
June Company repairs and calibrates the Fluke 87 III for electricians, technicians, and industrial teams.
Common Fluke 87 III problems we fix
- Readings inaccurate or out of spec — measurement-circuit drift, recalibrated against standards.
- A function dead — input or range-circuit faults, often after an overload, repaired.
- Input protection blown — fuse/protection circuit repaired after a miswire.
- Rotary-switch faults — intermittent function selection from a worn switch, repaired.
- Display or power faults.
FAQs
It’s an older 87 III — still repairable? Yes. These are rugged and very serviceable; input and measurement faults are repairable, then the meter is recalibrated so all functions read accurately, with a NIST-traceable certificate.
Do you calibrate all functions? Yes — every range is checked against our reference standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
