- Typical interval: 1 year (annual) is the most common recommendation for data acquisition modules to maintain published accuracy. Some users extend to 2 years based on historical stability and quality-system risk assessments, but 1 year is standard unless your quality plan specifies otherwise.

Fluke 2645A-UIM Calibration
Your Fluke 2645A-UIM Doesn’t Need Guesswork.
It Needs Calibration — Without the Runaround.
Your organization trusts the Fluke 2645A-UIM Universal Input Module to tell you the truth.
So why accept a calibration sourcing process built on phone tag, vague quotes, and one‑size‑fits‑all labs?

Whether you’re managing a single Fluke 2645A-UIM calibration or coordinating multiple instruments and locations, Rogue Calibration helps you eliminate guesswork, reduce downtime, and source calibration with confidence.
Better options. Better data. Better calibration sourcing.
Our partners provide traceable electrical calibration services to help ensure measurement accuracy, compliance, and continued usability of your equipment.
Quick Overview
- What it is: A universal, multi-function input module for the Fluke 2645A NetDAQ data acquisition mainframe.
- Typical use: Aggregating mixed sensor types (voltage, resistance, thermocouples/RTDs, frequency/period) for industrial, lab, and QA data logging and test automation.
- Status: Legacy/discontinued by manufacturer; widely available used/refurbished and supported by third-party calibration/service providers.
A Fluke 2645A-UIM Universal Input Module doesn’t lie—but it will expose lazy calibration. High‑accuracy measurements demand calibration performed by technicians who understand the 2645A-UIM, the specification limits, and the standards behind them.
Expert calibration verifies performance against traceable references, flags drift before it becomes failure and documents every adjustment. This isn’t box‑checking or sticker‑slapping. Its precision enforced. If your work depends on numbers you can defend, Rogue Calibration helps find the right calibration service provider for you.
