When working on a piece of equipment, many different measurements must be taken. To eliminate the need for several meters, the voltmeter, ammeter, and ohmmeter can be combined into a single instrument called a multimeter. An analog multimeter is referred to as a volt-ohm-milliammeter (VOM). A digital multimeter is also referred to as a DMM.
