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

Keysight Technologies has decided to discontinue the production of the 34401A digital multimeters (DMMs) on December 1, 2016. The last day to place an order for these products is November 30, 2016. Committed to providing world-class customer support, Keysight will continue to support these products for the standard period of 5 years. The replacement models for the 34401A are Keysight’s next-generation Truevolt Series DMMs.

The 34461A Truevolt DMM is a virtual drop-in replacement for the 34401A and offers improved usability and measurement technology. The Truevolt Series DMM’s graphic capabilities such as trend and histogram charts offer more insights quickly.
