Fluke 28 Series II Multimeter Repair
The Fluke 28 Series II is a rugged industrial true-RMS digital multimeter (Series II) built to extreme environmental specs, with Min/Max recording, measuring AC/DC voltage, current, resistance, capacitance, frequency, and temperature. Its accuracy depends on the input/measurement circuitry, so that’s where repair and calibration focus.
FlukeMeterRepair.com repairs and calibrates the Fluke 28 Series II for electricians, electronics technicians, HVAC techs, and industrial maintenance crews.
Common Fluke 28 Series II problems we fix
- Min/Max recording or True-RMS faults — those functions not working correctly, repaired and recalibrated.
- Input-circuit restoration — a damaged input stage, often after an overload, repaired.
- ADC recalibration — readings out of spec from converter drift, recalibrated against standards.
- Input protection blown — repaired after a miswire.
