The meter is a device bringing together in one case several tools for electrical measurements. These devices are capable of measuring voltages, currents, and resistances. To these essential functions, some more advanced options can be added, such as the continuity tester, the capacitance, the transistor tester, and even temperature.
- Difficulty: medium.
- Tools and materials needed: multimeter.
Presentation of the unit
A multimeter is comprised of a set of terminals where the measuring electrodes one branch, a screen where one reads the measure, and a control wheel.
The number of terminals may vary, but the device has a characteristic black terminal marked com and other specialized terminals by families measurement. Can be found for example a pair of terminals to measure the intensities, selecting according to the power to be measured, and another terminal for voltage, resistance and continuity tests.
