What is a digital multimeter? A digital multimeter (DMM) is a test tool used to measure two or more electrical values—principally voltage (volts), current (amps) and resistance (ohms). It is a standard diagnostic tool for technicians in the electrical/electronic industries. جهت ثبت سفارش با ما تماس حاصل فرمایید : 33993099 - 021

توضیحات محصول

Digital multimeters long ago replaced needle-based analog meters due to their ability to measure with greater accuracy, reliability and increased impedance. Fluke introduced its first digital multimeter in 1977.

Digital multimeters combine the testing capabilities of single-task meters—the voltmeter (for measuring volts), ammeter (amps) and ohmmeter (ohms). Often they include a number of additional specialized features or advanced options. Technicians with specific needs, therefore, can seek out a model targeted for particular tasks.

The face of a digital multimeter typically includes four components:

  • Display: Where measurement readouts can be viewed.
  • Buttons: For selecting various functions; the options vary by model.
  • Dial (or rotary switch): For selecting primary measurement values (volts, amps, ohms).
  • Input jacks: Where test leads are inserted
  • Test leads are flexible, insulated wires (red for positive, black for negative) that plug into the DMM. They serve as the conductor from the item being tested to the multimeter. The probe tips on each lead are used for testing circuits.

    The terms counts and digits are used to describe a digital multimeter's resolution—how fine a measurement a meter can make. By knowing a multimeter's resolution, a technician can determine if it is possible to see a small change in a measured signal.

    Example: If a multimeter offers a resolution of 1 mV on the 4 V range, it is possible to see a change of 1 mV (1/1000th of a volt) while reading 1V.

    Digital multimeters are typicaly grouped by their number of counts (up to 20,000) they display.

    Broadly speaking, DMMs fall into one of a handful of categories:

    • General purpose (aka Testers)
    • Standard
    • Advanced
    • Compact
    • Wireless
