Truevolt digital multimeters (34460A, 34461A, 34465A, 34470A) enable you to get quick insights, measure low-power devices, and maintain calibrated measurements with Keysight’s new patented technology. Truevolt offers a full range of measurement capabilities with higher levels of accuracy, linearity, speed, and resolution.

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.

Keysight Truevolt DMMs contribute less than 30% of the injected current than alternatives. Compared to some lower cost alternatives, Truevolt DMMs offer almost 100% less noise.

Ideally, no current flows into the measurement terminals of your DMM. In real measurement situations, there are always input currents creating additional measurement errors. Truevolt DMMs take care of input bias current. Some alternative DMMs offer 20% to infinitely poorer performance (some are too noisy to measure).

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.
