    Digital Multimeters

    Digital Multimeters (DMMs) are versatile electrical measurement instruments that offer exceptional accuracy in measuring a range of electrical parameters, including voltage, current, resistance, capacitance, frequency, and more. With digital displays, these multimeters provide numerical readings, minimising the chance of interpretation errors.

    At RS we have a great range of DMMs including Fluke Digital Multimeters, Keithley Digital Multimeters, Auto-Ranging Multimeters and our own RS PRO Digital Multimeters. The best digital multimeter to buy in terms of value, functions, and features will vary, depending on what you need the DMM to measure and in what environments and applications.

    Features and Functions of Digital Multimeters:

    • Multiple Ranges - DMMs often include multiple measurement ranges, ensuring they can accommodate a wide spectrum of applications. Auto-ranging digital multimeters automatically select the appropriate range, simplifying measurements for users.
    • Data Hold and Logging - Many DMMs feature a "data hold" function, allowing users to freeze a measurement reading for convenient recording. Advanced models may also have data logging capabilities for tracking measurements over time.
    • Backlit Display - Equipped with a backlit LCD screen, DMMs offer clear visibility even in low-light conditions, ensuring accurate readings in any environment.
    • Diode and Continuity Testing - DMMs provide diode testing to assess the functionality of diodes. Additionally, continuity testing emits an audible alert or visual indication when a circuit is complete, aiding in quick fault identification.
    • Auto Power Off - To conserve battery life, many DMMs feature an auto power-off function that switches the device off after a period of inactivity.

    How to use a Digital Multimeter?

    • Select the Parameter you want to measure, such as voltage, current, or resistance.
    • Set the Range - On manual-ranging models, select the appropriate range for the parameter you are measuring. Auto-ranging models do this automatically.
    • Connect the Probes ensuring proper polarity and connection.
    • Read the digital display of the measured parameter

    Digital Multimeters are indispensable tools for accurate electrical measurements across various applications. Their advanced features, ease of use, and precision make them an essential asset for professionals and enthusiasts alike. Whether you are diagnosing faults, conducting maintenance, or exploring electronic projects, a quality digital multimeter is considered a must have tool in your tool kit.
