Measuring with a Multimeter
|
||
The multimeter, or multitester, is a piece of electronic equipment that is mainly used to measure voltage, current or resistance. When working with components and circuits, it is very useful to be able to measure these values and find out what is happening. For example, we can discover if: batteries still have charge, materials conduct or insulate, a circuit has been setup and built properly (or if there are faults that need to be sorted out).

The multimeter's dial, above, has been rotated and set to read voltages up to 20 volts. To do the test, the meter's red positive (+ ive) probe should be connected to the (+) side of a battery and the black negative (- ive) probe to the (-) side of the battery. As you can see on the left, the meter's dial can be set to many other positions. Its position will depend on what you are measuring. To prevent the meter's batteries from running down, always turn the dial to the vertical OFF position when it is not being used - Have a go now! |
