Are you already an AT3600 or ATi owner?

Let us help you move to the next level of testing.

Discover the improvements in the AT5600, and how we can help you upgrade to our new platform

Our AT3600 Wound Component Tester, which was launched in 1996, is used by many of our valued customers throughout the world.
Manufacture of this product stopped in 2013, and Repair Services stopped in 2020.

One of the reasons we discontinued manufacturing the AT3600 was the very real issue of obsolescence of many of the components designed into the product.
We have succeeded over the years since we stopped manufacturing in providing full repairs for the product but, sadly, we can no longer offer this.

We will continue Calibration and Verification on the AT3600 for as long as we possibly can into the foreseeable future.
However, this is a great opportunity for our many customers to transition to our current product the AT5600. 

AT5600 - More Speed, More Features, More Productivity

The AT5600 Transformer Tester delivers accuracy, speed and reliability without compromise.

Customers already familiar with the AT3600 and ATi will see immediate benefits, as the AT5600 delivers twice the test speed of the AT3600, without compromising accuracy.
And we’ve designed it to provide an easy upgrade path, with no change in software or fixturing and common test programs across platforms.


The AT5600 offers you at least twice the test speed of the AT3600 or ATi.
This gives you a direct improvement in your cost of test, and doubles your efficiency.

See below for real examples of this enhanced performance and what this means to your Return On Investment (ROI).


The AT5600 also contains exciting new features not available on the older AT36 / ATi.

Compensation Storage - Save more time with automatic storage and recall of open and short compensation.
Kelvin Pre Test Check - A fast automatic check of your test connections to confirm your test connections and saves more time by stopping false failures


The AT5600 also contains new advanced ways to deploy more focused test strategies

Audit Test - Automate periodic extra tests on a sample from a batch

Diagnostic Test - Run extra tests in the event of a failure

Decrease Your Test Time - Increase Your Profitability

In today’s competitive market, the time to 100% test your output has a direct effect on the cost of manufacture, and hence end sell price.
Customers who have already deployed the AT3600 over traditional semi-manual test strategies have already seen the benefit that a one-test-station solution can provide.

From our years of experience in the market, we’ve improved our measurement techniques even further.
To demonstrate the benefit of upgrading to the AT5600, we’ve taken some typical customer test programs, and compared the execution speed with the AT3600. (click the Type Names for a web page detailing the testing)
