Display DMM results in ways you never have before

Easily display, save and document your measurement results

Easily set up and see your results and get actionable information faster

• See your results clearly on a bright, 4.3-inch (109 mm), high-resolution, color graphical display. Get answers faster using the intuitive, menu-driven interface. If you have questions about a key or functionality, press and hold the key to display built-in help on the subject.

• Customize display operation to meet your needs. Conﬁ gure your preferences and pull them up automatically at the next instrument start-up.

• Add customized labels to describe the instrument’s measurement your way.

• Get quick insight with graphical views of your measurement results: View readings, long-term trends (34461A only) and measurement histograms for a statistical view.

The bright, 4.3” high-resolution monitor is a prominent feature of Agilent’s new Truevolt multimeter family.

Number mode provides the traditional “digits” view of measurements.

Bar meter mode provides the number display along with an analog meter to provide a visual view of your measurements.

Histogram mode gives you a statistical view of your measurements.

Display DMM results in ways you never have before

Save and document your DMM’s data to your PC or mobile device using your preferred I/O:

• Control, capture and view your DMM’s data on your PC with a single click using the Digital Multimeter Connectivity Utility via USB, GPIB, LAN, or RS-232 (for older generation Agilent DMMs).

• Easily access the ﬁ les on your DMM using drag-and-drop to transfer ﬁ les via USB – no software required.

• Choose the I/O that works best for you: USB, LAN/LXI Core (optional on 34460A), GPIB (optional on 34460A & 34461A).

• Easily access the front-panel USB memory connector.

Test result screens allow you to show measurement statistics on the display.

The free DMM connectivity utility helps you get your job done faster

Capture and export data to your PC with drag and drop ease

Capture a digitized record, log measurements for longer periods under PC control or upload data captured directly from the instrument. Export data from a single DMM, or multiple DMMs with time alignment, to popular tools such as Microsoft Excel, Microsoft Word and MATLAB. Simplify test documentation and data analysis without the hassles of programming.

Visualize multiple DMM outputs at once

Display single measurements, charts, or histograms from a single instrument or up to four DMMs simultaneously. See what’s happening on your bench, all on one display—to spot correlated trends you might otherwise miss.

Trend chart mode (34461A only) displays your measurements over time.

Simplify instrument conﬁ guration

Instrument controls provide easy measurement setup and instrument state management. Reduce set-up times and quickly reconﬁ gure for new tests.

Speed up instrument discovery and connection for a broad range of Agilent DMMs

With one-click access to Agilent IO Libraries Suite, connect to DMMs via USB, GPIB, LAN or RS-232. Spend your valuable time testing your designs rather than setting up, connecting, and troubleshooting software.

Access and control tests on your DMM remotely on your mobile device

With a companion app available, DMM Mobile Utility, as a free download from the Apple App Store, view and control your LAN-enabled instrument wherever you go and receive email alerts when problems occur. Remotely remedy problems on long running tests to minimize project delays.

Measure with unquestioned Truevolt conﬁ dence

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 ﬂ at. 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, Agilent’s Truevolt technology accounts for measurement errors created by these real-world factors so you can be conﬁ dent in your measurements and it is only available on Agilent DMMs.

Truevolt technology starts with an analog-to-digital converter that enables a patented metrology-grade architecture. Using this architecture, Agilent 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.

What Truevolt technology means to you:

You can measure your real-world signals, not instrument error

Noise and injected current: Agilent 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.

Input bias current: Ideally, no current ﬂ ows 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 inﬁ nitely poorer performance (some are too noisy to measure).

You can measure your real-world signals with conﬁ dence

All Truevolt DMM speciﬁ cations 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.

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, 5 kΩ 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.

Digital AC rms measurements: For meters in this class, only Agilent 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 Agilent.
