Digital Multimeter

The new Keysight Truevolt digital multimeter (DMM) offers superior measurement accuracy, speed, and resolution due to its measurement capabilities and diverse price range.

Measuring low-power devices

Capable of measuring extremely small currents, with its picosecond resolution and 1 µ A range, it can be used to measure devices with extremely low power.

Maintain calibrated measurement accuracy

Automatic calibration can compensate for temperature drift, allowing you to maintain stable measurement accuracy while performing measurement tasks throughout the day.

Quickly obtain in-depth analysis

The Truevolt digital multimeter provides graphical display functions such as trend charts and histograms, which help you obtain in-depth analysis more quickly. Both models offer data recording mode (making trend analysis easier) and digital processing mode (for capturing transient signals).

Overview of Keysight Truevolt Digital Multimeter

The 4.3-inch high-resolution monitor highlights the uniqueness of the Keysight Tuevolt digital multimeter series.

Simulate bar display and digital display modes, allowing you to visually view measurement results.

The histogram mode provides you with a statistical view of the measurement results.

The digital mode provides a traditional measurement 'digital' view.

Using Truevolt technology to measure with confidence, you only need to focus on design quality and leave measurement issues to us

The actual signal on the rack or workbench is never smooth. AC and noise signals, as well as other environmental noise and instrument injected current, will be mixed in with the measured signal when passing through the power cord. Digital multimeters need to effectively suppress these external factors and eliminate their impact on actual measurement results. This processing capability can cause significant differences in measurement accuracy. Fundamentally, Keysight Truevolt technology can address measurement errors caused by the aforementioned factors, giving you confidence in the measurement results. This technology, inDede Technology Digital MultimeterUsed in the middle.

Truevolt technology is an analog-to-digital converter technology that supports metric level architecture. With the help of a metrology level architecture, Shide Technology achieves a good balance between measurement resolution, linearity, accuracy, and speed at a reasonable price. All of this stems from our strict adherence to the ISO/IEC 17025 industrial standard.

Measure confidently using Truevolt technology

What Truevolt technology means to you:

What you are measuring is the real signal, not the instrument error

Noise and injection current: The injection current of Keysight Truevolt digital multimeter is 30% lower than other major competitive products. Compared to many low-cost digital multimeters, Truevolt digital multimeters have noise levels that are over 100% lower!

Input bias current: Ideally, the current will not flow into the measuring end of the digital multimeter. But in actual measurement, there will always be an inflow of current, which will generate additional measurement errors. Truevolt digital multimeter can handle input bias current. There is a significant gap in this aspect between digital multimeters from other manufacturers, with performance being 20% lower, and sometimes measurement cannot be performed properly due to excessive noise.

Measure actual signals with confidence

All technical specifications of Truevolt digital multimeter have been tested according to ISO/IEC 17025 standard and all meet the requirements of the standard. As a result, the effectiveness of the laboratory or production line quality management system has been validated. Many low-cost digital multimeters cannot guarantee their measurement technical indicators.

Fully utilize the extended measurement function

Compared to 34401A, the Truevolt digital multimeter extends the current measurement range to 100 μ A to 10 A. We have also added temperature measurement capabilities (RTD/PT100, 5 k Ω thermistor) and extended diode measurement capabilities to higher 5V full range voltages, supporting engineers to test more diode types including LEDs.

Digital measurement of effective value in communication: Among similar products, only the digital multimeter from DeTech uses digital direct sampling technology to measure effective value in communication. Similar competing products use analog RMS converters, which have slower response speeds. However, the Keysight Truevolt digital multimeter uses the true effective value calculation method to measure the effective value of AC signals with peak factors up to 10, without any additional product errors. This technology can only be applied by DeTech.

Ensure a smooth transition:

The Truevolt series will be fully compatible and surpass 34401A, making you more

full of confidence

For over twenty years, the Keysight 34401A digital multimeter has established a good reputation among hundreds of thousands of users and gained widespread trust. Now, the Keysight Truevolt 34461A digital multimeter will inherit the 34401A and allow you to perform measurements faster and more confidently. The most important point is that you can easily replace 34401A with 34461A. There is no need to rewrite software programs or spend time adapting to a brand new interface.

Utilizing existing programs: The 34461A digital multimeter is an alternative product compatible with the 34401A SCPI instruction in the industry. Although other models may also be compatible with the SCPI command of 34401A, in most cases, they can only achieve partial compatibility.

Adapting to the new interface: The design work for the Truevolt digital multimeter was undertaken by the same design team as 34401A. When designing the Truevolt series digital multimeter, the team inherited the measurement functionality, reliability, and familiar interface of 34401A. You don't have to spend time adapting to the new instrument. For decades, users' recognition and trust in Shide Technology's measurement products have never changed. The new model will provide you with more powerful performance.
