Multimeter is the device that measures the various functions of electricity. In many technical areas of work like testing a wire or a circuit, multimeter is absolutely necessary. In the market, there are a wide range of Multimeter and different features. To help you further the Multimeter Guide is provided to see what points to be kept in mind to look for the best.
- Check for the safety measures – Multimeters are rated with different CAT levels that show that the particular Multimeter is required for the task at present or not. One has to deal with transient voltage as well as main voltage. CAT category also informs how much voltage it can handle or not. There are different voltage categories –
- CAT I – Only use for in circuits and is not connected to the main supply. 24V is the maximum it can handle.
- CAT II – It is for the electronics that are directly plugged with the main supply. 110V – 240 V it can handle.
- CAT III – It is for the electronic devices that are continuously plugged in with the main supply like refrigerators.
- CAT IV – It is used to work directly with the main supply on a building or a transformer.
CAT rated meters is designed to prevent us from electricity arching. It keeps us safe.
- Voltage, Range and Accuracy – According to the needs of a house, the meter should be installed. High end meters cover a lot of things that can be used to measure the main supply and MV. The range differs according to AC and DC power sources.
- Durability and Size – Size of the meter matters a lot depending upon the space to work in. For those who work in the field, they need a very durable tool. As it can slip, fall, mishandled or misplaced.
Multimeters can be used for other purposes too. There are many additional features added to it. Make sure when you purchase a multimeter, there is good warranty period that covers it from an accidental failures. Invest in the meter that safeguards you and your loved ones lives and gives you extra features. Every penny spent is worth.
The first multimeters were analog and they are still around. They have a mechanical gauge to measure it. Analog multimeters are relatively cheap than digital multimeters. Precision is the key and digital multimeters provide all of it. Analog meters have the chances of errors that are caused by looking at the wrong angle of the gauge. However one good feature is that when there is a voltage fluctuation, analog meter will show accurate numbers while digital will show erratic numbers.
One should read the Multimeter Guide thoroughly and different multimeters and their features to decide the best for your needs. Price should be the last consideration if it will be used in the field. Choose the best when it comes to deal with high voltage and amperage. There are many different multimeters in the market. Study their features well before deciding. It is easier to use the tool once the person is well versed with the product and its uses. There are different meters for residential or commercial uses.
