- Typical practice: 12-month interval.
- Tight-tolerance or reference use: consider 6 months.
- Always recalibrate after repair, significant transport/shock, or exposure to environmental extremes. Ultimately, follow your quality system and required measurement uncertainty; many labs set 1 year by default for legacy DC transfer instruments.

Fluke 801H Calibration
Your Fluke 801H Doesn’t Need Guesswork.
It Needs Calibration — Without the Runaround.
Your organization trusts the Fluke 801H DC Differential Voltmeter (DC Meter to tell you the truth.
So why accept a calibration sourcing process built on phone tag, vague quotes, and one‑size‑fits‑all labs?
Rogue Calibration flips that model.
We don’t calibrate your equipment.
We put calibration providers in competition for your business.
What That Means for You
- Access to calibration labs experienced with Fluke instruments
- Accredited and traceable calibration options
- Documentation suitable for ISO, FDA, and regulated environments
- Clear turnaround times and transparent pricing
- Control to choose the provider that fits your needs and timeline
Whether you’re managing a single Fluke 801H 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 legacy bench DC differential voltmeter/transfer standard for precision DC voltage comparison and null measurements.
- Typical use: Calibration labs and metrology tasks involving DC source verification, transfer measurements, bridge/null detection, and low-loading precision DC measurement.
- Status: Obsolete (out of production, support via used market and independent service/calibration providers).
A Fluke 801H DC Differential Voltmeter (DC Meter doesn’t lie—but it will expose lazy calibration. High‑accuracy measurements demand calibration performed by technicians who understand the 801H, 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.
