The probe tips on each lead are used for testing circuits.
They serve as the conductor from the item being tested to the multimeter. Test leads are flexible, insulated wires (red for positive, black for negative) that plug into the DMM. Input jacks: Where test leads are inserted.Dial (or rotary switch): For selecting primary measurement values (volts, amps, ohms).Buttons: For selecting various functions the options vary by model.Display: Where measurement readouts can be viewed.The face of a multimeter typically includes four components: Technicians with specific needs, therefore, can seek out a model targeted to meet their needs. Often, they include several additional specialized features or advanced options.
DIGITAL MEETER HOW TO
How to use a multimeterĭigital multimeters combine the testing capabilities of single-task meters-the voltmeter (for measuring volts), ammeter (amps) and ohmmeter (ohms). Fluke introduced its first digital multimeter in 1977. It is a standard diagnostic tool for technicians in the electrical/electronic industries.ĭigital multimeters long ago replaced needle-based analog meters due to their ability to measure with greater accuracy, reliability and increased impedance. A digital multimeter is a test tool used to measure two or more electrical values-principally voltage (volts), current (amps) and resistance (ohms).
