Maintenance

Returning the Instrument for Service

Returning the Instrument for Service 

Agilent Technologies aims to maximize the value you receive, while
minimizing your risk and problems. We strive to ensure that you get the test and measurement 
capabilities you paid for and obtain the support you need. Our extensive support resources and 
services can help you choose the right Agilent products for your applications and apply them suc-
cessfully. Every instrument and system we sell has a global warranty. Support is normally avail-
able for at least five years beyond the production life of the product. Two concepts underlie 
Agilent’s overall support policy: “Our Promise” and “Your Advantage”.

Our Promise means your Agilent test and measurement equipment will meet its advertised per-
formance and functionality. When you are choosing new equipment, we will help you with prod-
uct information, including realistic 
performance specifications and practical recommendations from experienced test engineers. 
When you use Agilent equipment, we can verify that it works properly, help with product opera-
tion, and provide basic measurement 
assistance for the use of specified capabilities, at no extra cost upon request. 9Often, many self-
help tools are available.

Your Advantage means that Agilent offers a wide range of additional expert test and measure-
ment services, which you can purchase according to your unique technical business needs. Solve 
problems efficiently and gain a 
competitive edge by contracting with us for calibration, extra-cost upgrades, out-of-warranty 
repairs, and on-site education and training, as well as design, system integration, project man-
agement, and other professional engineering services. Experienced Agilent engineers and techni-
cians worldwide can help you maximize your productivity, optimize the return on investment of 
your Agilent instruments and systems, and obtain dependable measurement 
accuracy for the life of those products.
