Benchtop digital multimeters

8 April 2015 Test & Measurement

New additions have been made to the Truevolt range of digital multimeters (DMM) from Keysight Technologies. The 34465A (6½ digit) and 34470A (7½ digit) help engineers to visualise their measurement data in multiple ways, get actionable information faster, and document their results more easily.

The instruments’ advanced graphical capabilities, such as trend and histogram charts, help engineers achieve greater insights faster. Both models offer three acquisition modes: continuous running for typical measurements, data-logging for easier trend analysis, and digitising for capturing transients.

These DMMs offer deeper memory for data storage than previous generations, and also provide the ability to measure very low current in the 1 μA range with picosecond resolution, for measurements on very low-power devices. They feature auto calibration which compensates for temperature drift.

In contrast with most DMMs that show results on a low-resolution numeric display, the Truevolt series boasts a 4,3”, high-resolution colour display to view numerical readings, measurement trends, histograms and statistical data. They can also save and recall their measurement states and display preferences.

The Easy File Access feature provides simple USB connectivity between the DMM and a PC using standard USB media transfer protocol. In addition, the meters include drag-and-drop measurement data capability, adjustment of instrument settings, and the ability to send screen images to PC applications without additional software.

BenchVue software lets engineers control, capture and view Keysight’s DMMs simultaneously with other Keysight bench instruments and with no additional programming. With a single click, engineers can transfer data to a PC via USB, LAN or GPIB for additional viewing and analysis.
