Digital Multimeters 34460A, 34461A, 34465A (6½ digit), 34470A (7½ digit)

Get more insight quickly

Truevolt DMM's graphical capabilities such as trend and histogram charts offer more insights quickly. Both models also provide a data logging mode for easier trend analysis and a digitizing mode for capturing transients.

Measure low-power devices

The ability to measure very low current, 1 μA range with pA resolution, allows you to make measurements on very low power devices.

Maintain calibrated measurements

Auto calibration allows you to compensate for temperature drift so you can maintain measurement accuracy throughout your workday.

Measure with Unquestioned Truevolt Confidence

Worry about the quality of your design, not the quality of your measurements

In a rack or on a bench real-world signals are never flat. They have some level of AC signal riding on top from power line noise, other environmental noise, or injected current from the meter itself. How well your meter deals with these extraneous factors and eliminates them from the true measurement makes a big difference to your accuracy. Behind the scenes, Keysight’s Truevolt technology accounts for measurement errors created by these real-world factors so you can be confident in your measurements and it is only available on Keysight DMMs.

Truevolt technology starts with an analog-to-digital converter that enables a patented metrology-grade architecture. Using this architecture, Keysight delivers a good balance of measurement resolution, linearity, accuracy, and speed at a value price, all derived and guaranteed per ISO/IEC 17025 industry standards.

Benefit from a new perspective by visualizing multiple DMM’s at the same time

Display single measurements, charts, tables, or histograms from a single instrument or multiple DMMs simultaneously to correlate trends you might otherwise miss.

Record measurements and export results in a few clicks

Log and export data quickly to popular tools such as Microsoft Excel, Microsoft Word and MATLAB for documentation or further analysis.

Access and control tests on your DMM remotely

With the companion BenchVue Mobile app, monitor and respond to long-running tests from anywhere.

Digital AC rms measurements: For meters in this class, only Keysight uses digital direct sampling techniques to make AC rms measurements. This results in a true rms calculation technique that avoids the slower response of analog RMS converters used in all other vendor’s 6½ digit DMMs. This allows for crest factors up to 10 without additional error terms. This is a unique, patented technique – only used by Keysight.

You can measure your real-world signals with confidence

All Truevolt DMM specifications are tested and guaranteed for compliance with ISO/IEC 17025 standards so you can prove the effectiveness of your lab or production line’s quality management system. Many lower-cost DMMs in this class do not carry a guarantee of their measurement specifications.

You can take advantage of expanded measurement functionality

Compared to the 34401A DMM, Truevolt DMMs offer expanded current ranges from 100 μA to 10 A. We have also added a temperature measurement function (RTD/PT100, thermistor). Additionally, diode measurement capability has been expanded to allow a larger full-scale voltage to be measured (5 V) to enable the measurement of more diode types such as LEDs.

Migrate with confidence: Everything you depend on with the 34401A and more

Like most 34401A DMM owners, you rely on your DMM and you trust the answers it gives you. Now, with the Keysight Truevolt 34461A DMM, you can get all of the advantages of the 34401A and more. Now you can get faster answers and have even more confidence in your results. The best news of all? You can migrate from the 34401A to the 34461A without a hassle. No need to rewrite your software programs or spend hours learning a brand-new, complicated interface.

Use your existing programs: The 34461A DMM is the industry’s only 100% drop-in, SCPI-compatible replacement for the 34401A DMM. Other DMMs may claim 34401A SCPI compatibility, but only a subset of SCPI commands are implemented.

No long learning curve: The Truevolt DMMs were designed by the same team that created the 34401A. The team kept 34401A measurements, reliability and familiarity in mind as they created the Truevolt family of DMMs. So you can use it without spending hours learning how.
