- Typical industry practice is every 1 year (annual calibration). Some labs may justify a longer or shorter interval based on stability data, usage severity, and quality system requirements. For use as a primary DC source or in accredited labs, a 6–12 month interval is common unless your historical drift data supports extension.

Quick Overview
- What it is: A precision DC voltage calibrator (legacy Fluke model) used as a laboratory-grade source for DC voltage.
- Typical use: Calibrating/verifying DMMs, voltage references, and DC measurement ranges in metrology and calibration labs.
- Status: Obsolete (out of production and no longer supported by the OEM).
The Fluke 5440A Direct Voltage Calibrator is trusted because it’s engineered for accuracy in demanding environments—but that accuracy only holds if it’s calibrated by experts who truly understand the instrument.
Measurements at this level leave no room for shortcuts or generic adjustments. Expert calibration ensures your Fluke 5440A is tested against traceable standards, adjusted correctly when needed, and documented properly—so the numbers you see are the numbers you can stand behind.
When decisions, safety, and compliance are paramount, precision isn’t optional. It’s earned through professional calibration done right.
