Explore analysis of high-frequency error sources in oscilloscope calibration. Gather insights into the causes, impacts, and methods to mitigate these errors to enhance your accuracy.
Calibration standards are devices that are compared against less accurate devices to verify the performance of the less accurate devices.
Get 7 free measurement uncertainty training materials including videos, webinars, & articles. Fluke also offers a paid, online course for deeper knowledge.
In metrology, what do you do when your curve-fitting software program doesn’t work because you’re dealing with a non-linear equation? Learn here.
Fluke experts show you how to calibrate a pressure rotameter including a step-by-step rotameter calibration procedure, calibration curve, and tips.
It is becoming my opinion that ISO 17025 needs to be revised. This is the first of a series of blog posts that I will be making to demonstrate why the revision needs to be made.
Another NCSLI conference is in the books. This year, the metrology faithful (and budget funded!) once again gathered to gain knowledge through tutorials and technical presentations, contribute to the industry through attendance of committee meetings, talk to vendors at the exhibition, network with some of the world’s experts in metrology and spend time with old friends. There were so many great things happening that I didn’t even have time to compose a single tweet!

Should you bring humidity measurement and calibration in house? Learn to answer this question from the perspective of ROI, requirements, and workload.
This video includes reminiscences from Fluke and Fluke Calibration associates who remember what it was like to work at Fluke ”back in the day.”
The triple point of argon (83.8058 K ) is one of the most commonly used fixed points for the calibration of standard platinum resistance thermometers (SPRTs) at temperatures below 273.16 K. It’s a defining fixed point of the International Temperature Scale of 1990 (ITS-90). Fluke Calibration recently designed a new Triple Point of argon system with the goal in mind of achieving both efficiency and accuracy in calibrating SPRTs.

Consider if your company would be best served by specifying traceability to the SI instead of to your local NMI.
Whether you’re speaking to a small group of colleagues at your company or a group of professionals at MSC or NCSLI, here are some tips to help you succeed – and perhaps even enjoy your experience as a public speaker.
In this article, electrical calibration expert Marty Kidd explains why someone needs this type of product. He also explains why owners of an old Fluke 5790A should consider moving up to a new 5790B.
In 2012, the Association of German Engineers developed VDI/VDE-2623, which defines and establishes a Calibration Data Exchange Format. VDI/VDE-2623 establishes a rigid Extensible Markup Language (XML) data structure with both required and optional fields
If you are currently outsourcing or turning away pressure calibration business, you may be doing so unnecessarily. The barriers to enter the pressure calibration business can be overcome fairly easily.
While there’s no “one size fits all” answer, see this post for helpful guidelines on how often you should calibrate thermometers, test equipment, multimeters, etc.
How do you choose a multi-product electrical calibrator? They are not all the same. Read this short blog post to learn seven essential points to consider.

The purpose of this paper is to truthfully answer various questions one might have with regard to resistance bridges and readouts after reading some of the sales hype arguing that AC is better than DC or vice versa
A platinum resistance thermometer (PRT) is a thermometer constructed from a high purity platinum element (wire-wound coil or thin film) placed in a tube of metal or glass and sealed with an inert atmosphere and/or mineral insulator.

讓BIPM在全球范圍內管理SI的主要好處是校準的互操作性。這意味著,世界各地都在使用相同的測量系統和定義。這樣,美國的某人在澳大利亞購買一個1歐姆的電阻,并確信按照美國的標準對其進行測量時也為1歐姆,反之亦然。為了實現互操作性,我們需要所有的測量結果都可溯源至同一定義。
If you are purchasing a calibrator to calibrate pressure measurement devices, follow these 2 simple steps to ensure you get what you need.
See why Roger Pineche, Director of Engineering at Fluke, says the new 8588A and 8558A are the best benchtop multimeters in terms of stability & accuracy.
Pressure calibration can be challenging in the best of environments. Working in an area that has the potential for explosion takes the degree of difficulty to another level—one where the technician needs proper training and equipment.
