Use a Keysight Digital Multimeter to Measure with Unquestioned Confidence

When designing a product, you should not worry about the quality of your measurements. Instead, your focus has to be on the quality of your design. Our digital multimeters are all built for reliably accurate measurement every time. They come with built-in technology that eliminates extraneous noise factors from the true measurement to make a big difference to your accuracy. Keysight delivers digital multimeters with a good balance of measurement resolution, linearity, and accuracy, all derived and guaranteed per ISO/IEC 17025 industry standards.

Industry’s Leading-Edge DCV Linearity Accuracy and Lowest Internal Noise

The Keysight 3458A digital multimeter (8.5 digits) has been the industry’s benchmark for its remarkable DC accuracy and stability. It is the tool for making precision measurements with the highest degree of accuracy, transfer standard for instrument calibration, or high throughput digital multimeter measurements in manufacturing.

Learn how to use the 3458A to perform automated or manual ratio measurements to determine the value and measurement uncertainty of an unknown voltage compared to a known reference voltage. In addition, learn how to minimize measurement errors by eliminating instrument-contributed errors or using metrology-grade transfer measurement procedures.

Frequently Asked Questions About Digital Multimeters (DMMs)

What Is a Digital Multimeter?

A multimeter refers to a measuring meter that makes multiple types of measurements, such as alternating current (AC) or direct current (DC) voltage, AC or DC current, resistance, temperature, capacitance, and more parameters. A modern digital multimeter uses digital and logic technology to miniaturize and enable many features in its internal system. With digital technology, digital multimeters can have graphical displays, perform data logging and signal digitizing capabilities, programmability, and communicate with external devices.

How to Read a Digital Multimeter?

Most handheld or benchtop digital multimeters have measurement displays in digits. The number of digits on display usually corresponds to the level of resolution the digital multimeter can measure. Resolution is the level of detail that is quantifiable on a digital multimeter. Therefore, the higher the number of digital multimeter display digits, the higher the resolution. It is common to see handheld digital multimeters with display digits of 3.5 and 4.5 digits. Bench digital multimeters tend to have display digits of 5.5 digits, 6.5 digits, 7.5 digits, and even 8.5 digits.

How to Use a Digital Multimeter to Check for Power?

A digital multimeter can measure current (I) and voltage (V). If you have both measurements, calculating the DC power is simply multiplying both the current (I) and voltage (V) measurements. Most digital multimeters have an internal architecture that inhibits their ability to measure both at the same time. However, if you use a few techniques and the right equipment, you can get a good I and V measurement from your benchtop DMM.

Choosing a Benchtop Digital Multimeter

Digital multimeters are a key tool for many engineering benches. Like many of us, you may find it challenging to choose the digital multimeter that is right for you. It may mean the ability to measure the extra range, to gain better accuracy, or to measure the small transient signal that matters a lot. The right benchtop multimeter gives you the extra edge to come out with a product that is better than your competitors.
