What is a Multimeter


A multimeter is a device that can measure two or more electrical values such as voltage (volts), current (amps), resistance (ohms), capacitance (farad), frequency, inductance, conductance etc. However, most advanced models are designed to measure rotation per minute(RPM), microamps, decibels and more. It is also known as VOM (volt-ohm-milliammeter). They are generally portable and handheld device. Nowadays multimeters have improved to the point where you don’t even need a lot of technical knowledge to operate one. Electricians, auto mechanics or other types of technicians or even a householder needs Multimeter. DIYers, hobbyists, and peoples who are involved in home improvements are other groups of individuals love this test tool as well.

Multimeters are mostly known as a troubleshooting device. It comes very handily making quick work of finding faults in a circuit. Through this smart tool Industrial and household electrical problems can be determined. Also, electronic equipment, domestic appliances, and wiring systems fault can be analyzed using a multimeter.

Multimeters also come with accessories like leads, clamps, probes, and others. A cheap multimeter can cost you $10 to $25 dollar only with minimum applications. But a quality multimeter costing $30 or above can give you precise reading, more functionality, and comfortability. We have a wide range of reviews in multimeterreview.com. We will assist you with decent reviews of best multimeters available at different price levels.

Types of Multimeter

This modern device is mainly of two types. There are different types of multimeters available in the market but they are categorized as Analog Multimeters and Digital Multimeters. Analog meters measures value in the continuous range of values whereas digital circuits measures values in discrete increments. Analog multimeters give you a display readings using a microammeter with a moving pointer. While Digital multimeters have a numeric display. Some advanced digital multimeters may show you a graphical bar representation of the measured value. Although DMM are most popular still analog multimeters are preferred by tech lovers. The popularity of DMM is due to its cost, portability, precision, and user-friendliness. There is another category of standard diagnostic tool namely Bench multimeter. It is mostly used in research laboratories.

You need the right kind of tool to find out electrical problems in your car or any big instrument built with a complex mechanism. Is such a situation you need a professional tool that gives you the best support to meet your needs. We will let you drive deep into the device so that you can comfortably grab yours.

Analog Multimeter

Analog Multimeters were first manufactured before the digital multimeters. It can measure from a fraction of a unit to several thousand units. While a digital multimeter can be capable of measuring units of a few parts per million. This is why analog multimeters are losing its popularity. The lack of multifunctionality is a drawback for analog multimeters. Still, the nice visual reading is favorite among hobbyist. A needle indicator that swings across the calibration scale gives you the reading.

The best advantage you can get from an analog multimeter is when you check continuity of several wires at a time. You will get a quicker result. As analog meters do not take the hassle to convert the reading into another form. Analog multimeters are also durable. It does not contain sensitive electronics such as the LED display. But while you are calibrating make sure to put your meter is a steady place as taking a reading in a vibrational environment may result in an inaccurate reading. Also, make sure your analog meter has a plastic or rubber casing to immune from physical damage.

A high sensitive meter is always best as an analog multimeter. If you are dealing with highly sensitive circuit measurement an analog multimeter can outperform a digital multimeter. That is the main reason why it is still preferred by many and you cannot just ignore the analog mm.

Digital Multimeter

The digital multimeter combines multiple measuring features in a single device. These devices usually include some advances features for technicians. For a DMM “resolution” describes the “sensitivity” of a particular device. Due to the demand for high sensitivity modern dmm’s consists of auto-ranging functionality. You need not set the range manually. As the evolvement of technology in this modern age DMM are getting more and more precise. There are lots of DMM available in the market with high precision and sensitivity. DMM also has more impedance than analog multimeters. So it is clear that the usefulness of a DMM is pretty handy as working on different electronics at a different time can be a necessity. It is efficient to have a DMM with you.

Digital multimeters are of three types considering the range of functionality provided by these multimeters:

  • The auto-ranging multimeter,
  • Clamp digital multimeter and
  • The Fluke digital multimeter.

Autoranging digital multimeter

This is the easiest type of multimeter that automatically measures the readings. You don’t even need to switch to what is being measured. The meter is the easiest equally the most expensive of all.

People who have less technical knowledge are highly recommended to use an auto-ranging multimeter. As you will not require to look for the range to set before taking a reading. There is a drawback, it can measure one component at a time.

Clamp digital multimeter

A clamp meter can measure the flow of electricity. It is named as clamp meter because this meter uses a clamp to take the current measurement. While the probes measure the voltage. It is also capable of measuring power consumption and wattage. Remember, you need to set the category of the equipment to get the desired reading.

Fluke Digital Multimeter

A Fluke Multimeter comes with a wide range of features. You can access different functions as per the requirement of your project. Modern devices contain advanced features all you need from an electrical testing device. As an electrical troubleshoot expert, check out our in-depth reviews of such multimeters. We also recommend this types of a multimeter to the complete newbies.


Most electrical technicians know the importance of having a multimeter in their home depot. It can save a lot of time, hassle and money by accurately troubleshooting electrical faults. Find out here what things to consider when choosing the Best Multimeter for you.
