Not sure what a multimeter is? Well, if you want to have an instrument that can be used to measure electric properties such as current, voltage and resistance over several ranges of value, you should have a multimeter. Alternatively, a multimeter is referred to as a circuit analyzer, multitester, or the Volt-Ohm-Meter (VOM). A multimeter is a multi functional device. By turning the switch, you can use this tool as a Voltmeter, Ammeter or as an Ohmmeter.
So instead of having separate meters, try to have a multimeter that combines many different features. Most car mechanics and car owners use multimeter on batteries and motors for the purpose of detecting malfunctions and lessen their cause as soon as possible. To have a perfect process for this case, find the best multimeter. You must be careful in finding the best one for you to get the right one base on the specified sensitivity range you would like the most.
What Makes Multimeter Useful
Multimeters are important to measure resistance when you are working with the switches, fuses, sensors and other components of your vehicle such as lighting, stereo as well as ignition coil. Measuring the resistance of the vehicle will help you prevent further damages before it would end up on buying a new one. There are multimeters as well that offers the ability to read continuity. This ability is essential to test fuse, broken wires and any parts that pass current.
When it comes to current, a multimeter is also useful. Indeed, a multimeter is not just a simple tool; it is an electronic measuring instrument that merges many several functions in one unit. It is a hand-held device which is highly useful for finding and correcting basic faults and field service work. Multimeters can also be used for bench instruments in order to get high degree of accuracy. They can also be used to troubleshoot electrical problems in different industrial and household devices like electronic equipment, domestic appliances and wiring systems as well as motor controls and power supplies.
Types of Multimeter
There are two types of multimeter. Both of them may sound useful or good to use but you as a wise user should choose which one really works best.
- Analog Multimeter – The analog multimeter is commonly based on a microammeter whose pointer moves over a scale calibration. However, most electricians find it hard to use this kind for many reasons.
- Digital Multimeter – The digital multimeters or DMM have a digital or liquid crystal display (LCD) where the readings of every measurement appear in exact numerical values and the display will alert you at the same time to be ready for any pertinent symbols and warnings.
Benefits you can get from Digital Multimeters
Whether you use analog multimeter or digital multimeter, consider the reason why most electricians find digital multimeters to be more useful. Digital multimeters have dial that will allow you to select the function you want to measure and get the desired readings really clear and understandable. The dial of digital multimeters is also essential for any kind of electricity-related measurements and it is also good for determining the range of measurement that may occur.
The range of the measurement you selected on the dial shows the placement of the decimal point as what you can see on the LCD screen. The position of the decimal point concludes how refine or accurate the reading of your multimeter is. Digital multimeters also have auto-polarity for direct readings of the current for you to see the positive or negative voltage. Digital multimeters also have sample-and-hold feature which shows the most recent reading for examination.
If you want graphic results, digital multimeters allow you to have graphic representation like bar graph for a more effective reading. Having a simple data acquisition will also help you in recording over a lesser given period of time. These digital pocket multimeters are highly useful in a variety of measurement applications. Whether you want to use them for manufacturing, automotive or food service equipment, digital multimeters are always great.
Manual Ranging Versus Auto-Ranging
To have the best multimeter for electronics, auto-ranging is a great advantage. This is because auto-ranging digital multimeters save you from hassle and stress of finding which range value the resistance, voltage or whatever electrical characteristic you are looking for. With the auto-ranging digital multimeter, it will find the value for you. On the other hand, if you would like manual ranging multimeter or those “not auto-ranging” ones, they offer preset ranges so you have to know which range of value it falls from.
However, auto-ranging digital multimeters are known to be more expensive, this is why the author Jason L. Trevino writes this article to show you the right way to the high-quality yet affordable digital multimeters in the market. A great tool does not have to be expensive.
