Mainly, a multi-meter is used to measure the electrical potential across something. In this mode, multi-meter is known as voltmeter and the readings are measured in volts. Other modes of multi-meter are amp-mater and ohm-meter. In case of an ohm meter, it measures the electrical resistance and the readings are measured in ohms. In case of an amp-meter, it is used to measure the electric current across something.

Nowadays, there are multi-meters out in the market that can measure the temperature and can work as continuity testers as well. A multi-meter with hard plastic covering is considered the best. The reason for this is that it can sustain the rough conditions and can last for years.

The first impression of a nice multi-meter is that it comes with a strong plastic case making it tough and durable. A digital multi-meter also has an LCD screen for displaying the readings. Choose the screen size according to connivance so that you do not find it difficult to read the readings.

You will find a large rotating knob (function knob) below the screen. With the help of this knob, you can switch between the different modes of the digital multi-meter. Using this knob only, you can change it from voltmeter to amp-meter, and then to ohm-meter. Choose the one that offers easy handling when it comes to switching multi-meter to different modes.

A multi-meter that has got crocodile clips can prove superior in many conditions than the multi-meters with no crocodile clips. Crocodile clips can hold the item that needs to be measured. In case of ordinary probes, you have to hold the probes all the time against the face of the item. Such crocodile clips can hold the testing surface in place while you are busy in taking the reading.

Purchase a multi-meter which has the feature of auto turn-off. This auto turn feature automatically turns the multi-meter off if it remains ideal for a long time. Auto turn-off feature also saves the batteries if you have forgotten to turn off the power.

A multi-meter can be purchased from any of the electrical equipments store. Nowadays, it is also available on the Internet and you can easily purchase it online.

A digital multi-meter in the home is extremely useful and convenient. With it, you can test your batteries, test fuses and can perform many other things. It is a useful and must tool for every home nowadays.
