Description
Fluke 753 Process Calibrator Repair
The Fluke 753 is a process calibrator – it sources and measures the signals a plant’s instrumentation runs on: milliamp loops, voltage, RTDs, thermocouples, frequency and pressure through external modules. It is several instruments in one case, so faults are usually confined to one function.
Certified technicians at June Company service the Fluke 753 for process instrument technicians, plant calibration teams, refinery maintenance crews, and field service engineers. Every instrument is repaired at component level and verified against reference standards before it ships back, with the measured results documented.
Common Fluke 753 problems we fix
- Display, keypad or interface faults.
- Battery, charging or power faults.
- mA source or measure out of tolerance – the function these instruments are used for most, and the first place drift shows.
- One function failing while the others work.
- Thermocouple or RTD readings inaccurate.
- HART communication faults – the instrument no longer talking to the transmitter, which is separate from any measurement problem.
- Pressure module not recognised – frequently the interface in the calibrator rather than a failed module.
- 24V loop supply not driving a transmitter.
