Migration from the 34401A to the New 34461A Truevolt Digital Multimeter (DMM)

The 34461A DMM is the next-generation 34401A DMM. This new Truevolt DMM was designed by the same group as the 34401A DMM, with many of the same R&D engineers participating. With this continuity of experience and expertise, Keysight has made a DMM that is a virtual drop-in replacement for the 34401A while continuing to improve usability and measurement technology.

If you are looking to migrate from the 34401A to a 34461A DMM and want to fully understand all of the differences between the two models, the application note below will help you migrate from your 34401A to a 34461A DMM effortlessly.
