6½ digit digital multimeters

Paul Boughton

Amplicon has introduced the 34461A digital multimeter (DMM) from Keysight Technologies, formerly Agilent. These DMMs offer several advantages over previous models. They help engineers see their measurement data in new ways, get actionable information faster and document their results more easily. Exclusive Truevolt technology reduces extraneous factors such as noise, injected current and input bias current for increased measurement confidence.

The Keysight 34461A DMM is a direct replacement for the 34401A DMM, and was designed to make migration easy for current users of the 34401A. The 34460A offers a basic entry point to the 6½ digit class of DMMs.

Compared with the 34401A DMM, the new 34461A offers expanded current ranges from 100µA to 10A. Both the 34460A and 34461A have a temperature measurement function (RTD/PT100, thermistor) and expanded diode measurement capability to allow measurement on a larger full-scale voltage (5V) making it possible to test more diode types, such as LEDs.
