    Digital multimeters

    All digital multimeters combine the features of an ammeter, a voltmeter, and an ohmmeter. Figure 2 shows a typical DMM, although different models may have a different number of digits in the display unit and the input/output jacks may be in slightly different places. Since a DMM is an important tool, you will want to learn how to use one correctly.
