The 34401A digital multimeter (DMM) is the industry standard. Its accuracy, ease of use, and flexibility have attracted users for more than two decades and its low cost of ownership and high quality have helped it to be one of the most successful products in the history of Keysight Technologies, Inc. Many engineers do not even evaluate other DMMs when they want to order one; they know the 34401A will work for them. It is an essential meter for bench and automated test applications.
The 34461A DMM is the next-generation 34401A. This new DMM was designed by the same group as the 34401A, 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 and offers improved usability and measurement technology. The Truevolt Series DMM’s graphic capabilities such as trend and histogram charts offer more insights quickly.
