This unit
The Fluke 8400A is a 5½-digit precision digital voltmeter engineered for systems integration and laboratory measurement applications. This benchtop instrument delivers DC voltage measurements across five ranges from ±0.1 V to ±1000 V with 1 µV sensitivity and exceptional 0.002% basic DC accuracy. The design leverages Fluke's Recirculating-Remainder A/D conversion technique to ensure high long-term accuracy, superior linearity, and reliable environmental stability.

Fluke 8400A/FM — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Fluke 8400A/FM. Calibration covers calibration scope varies by instrument type: vacuum gauges are verified at multiple pressure points against NIST-traceable pressure standards; spectrophotometers at wavelength accuracy and photometric accuracy points; strain gauge indicators at bridge excitation accuracy and full-scale output accuracy; pH meters against certified buffer solutions at pH 4, 7, and 10.. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Fluke 8400A/FM faults: vacuum gauge filament failure (ionization gauges), spectrophotometer D2 lamp end-of-life, wavelength motor failure, strain indicator front-panel binding post corrosion, pH electrode conditioning failure. Most specialty laboratory instruments fail at their electromechanical interfaces first — vacuum gauge connectors and filament assemblies, spectrophotometer lamp housings and motor drives, strain indicator binding post corrosion. Component-level repair is standard; manufacturer support for legacy instruments is often limited, making third-party bench repair the practical path.

Fluke 8400A/FM calibration cost
NIST-traceable calibration for the Fluke 8400A/FM is $450 (standard — pass/fail certificate and calibration sticker) or $650 (full measured data at every test point, reference standards documented, traceability chain included). Calibration for this instrument covers calibration scope varies by instrument type: vacuum gauges are verified at multiple pressure points against NIST-traceable pressure standards; spectrophotometers at wavelength accuracy and photometric accuracy points; strain gauge indicators at bridge excitation accuracy and full-scale output accuracy; pH meters against certified buffer solutions at pH 4, 7, and 10.. Turnaround is 1 to 3 business days after receipt. See full calibration details →
