Fluke 1586A Super-DAQ Temperature Scanner Repair
The Fluke 1586A Super-DAQ is a precision temperature/data-acquisition scanner — a high-accuracy multichannel logger optimized for temperature (PRT/RTD/thermocouple/thermistor) plus DC measurements, used for temperature mapping, validation, and calibration. Its accuracy depends on the input scanning/multiplexer channels, the precision measurement circuitry, and the reference, which is where service and calibration focus.
FlukeServiceCenter.com repairs and calibrates the Fluke 1586A for temperature-calibration labs, pharmaceutical QA, and food-safety validation teams.
Common Fluke 1586A problems we fix
- Input-channel / scanning-module faults — a channel reading wrong or dead, often after an over-range input, repaired and recalibrated against standards.
- Multiplexer / relay faults — channels mis-scanning or crosstalking, repaired.
- Measurement accuracy out of spec — converter or reference drift, recalibrated.
- Won’t communicate — the host/network interface, repaired.
- Display or power faults.
FAQs
A channel on my 1586A reads wrong — fixable? Yes. Channel, multiplexer, and measurement faults are repairable, then the inputs are recalibrated so every channel reads accurately, with a NIST-traceable certificate.
Are all channels verified? Yes — each channel is checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.
