Skip to content Overview of Digital Multimeter There is a multitude of digital multimeters available in the market and online for testing currents, voltages, resistances, capacitances, and many other parameters. Digital Multimeter Specifications DMM Specifications The performance of a digital multimeter is decided by the digital multimeter specifications.
Input Impedance Accurate measurements can be attained by choosing a multimeter with high input impedance if you want to measure the more sensitive electronics. Frequency Measurement Some DMMs are capable of measuring the frequency and in turn monitoring voltage and current within a frequency range.
Temperature Measurement If you have frequent temperature monitoring needs, get a digital multimeter with a dual differential temperature function; this functionality allows you to measure two temperatures simultaneously. Prior to the development of multimeters also called multitesters , individual meters were used to test circuits for voltage voltmeter , resistance ohmmeter , and current ammeter. While a DIYer can usually get by with a no-frills tool, electricians and HVAC pros will benefit from some of the advanced options found on professional models.
Read on to learn what to look for and to find out why we recommend the favorites listed below:. For greatest versatility, make sure the multimeter you buy is capable of testing both types of electrical current, alternating current AC —the electricity that flows through the outlets in your home—and direct current DC , the electricity found in batteries. Additionally, in order to qualify as a multimeter, the tool must perform at least two of the following three basic electrical tests:.
In addition to testing voltage, resistance, and current, advanced digital multimeters often come with the ability to test the following:. The classic analog multimeter features a dial with a needle like the old-time speedometer on a car , and for some, this type of readout is easier to see, especially in bright sunlight when numbers on a digital display can be difficult to decipher. Some digital multimeters come with a backlit screen that makes the display easier to see in bright light, and some include an auto shut-off feature that turns the meter off after a few minutes of nonuse.
The next thing to look for is a good display. Lastly, look for automatic ranging. The last thing you want to do is mess around with having to set the range of your meter before every measurement. Of course, cost effective is different for different people. Of course, there are multi-hundred dollar meters for those who have special needs.
Our choice is the Greenlee Autoranging DM It meets all of our requirements at the lowest price of our three recommendations. It will likely last you a lifetime and keep up with anything you throw its way. Next to checking continuity, measuring voltage will be the most common task you do with your multimeter.
Before you can measure voltage, you need to make sure your meter is configured properly. Next, place the red probe in the jack labeled voltage. You run the high risk of damaging your meter, or at the least blowing a fuse in your meter if you use the wrong jack..
Next, set the dial to measure DC voltage. The DC voltage icon is usually a V, followed by a solid line over a dashed line. To get a voltage reading, set touch the black probe to the GND or - terminal of a battery. You should get a voltage reading of the battery. Now, reverse the wires. This practical toolkit is a good choice for beginners, engineers, and electricians.
With this multimeter, you can also test the working of diode and transistor. It is a small size portable device for measuring the parameters like resistance, voltage, current and used to assemble, repair and diagnose the circuits. Crenova is an auto-ranging multimeter kit that is widely used in schools, colleges, laboratories and other sources. It is most prominent among all other multimeter devices of various brands.
You can also test the respective parameters on a circuit breaker, distribution boards, and industrial equipment. Auto-ranging multimeter allows you to select the correct measurement range when you deal with various components from electronics to electrical sources. This wonderful device can switch to other functions for performing specific tasks like measuring the readings of resistance, voltage, and current on display unit.

Neiko digital multimeter is a portable, general purpose multimeter to test wires, batteries, fuses and other electrical components.
It is a very safe tool for repairing domestic and automotive settings. An LCD screen accurately displays current, voltage and resistance. Black and red test leads help to observe the performance of diodes, fuses, transistors, and wires. This digital multimeter kit component is as follows:. It is equipped with large LCD screen with bright backlight for easy readings. It is safe to use on hybrid HV circuits and it is suggested to use proper safety equipment and manufacturers safety procedure while testing or servicing hybrid vehicles.
Thsinde is a small yet reliable seller of electronic components. The brand is known for developing electronic measurement tools that are versatile and show accurate readings. The multimeter features counts and can detect parameters on a wide range. Once the voltage crosses V RMS , the multimeter will display a light and emit a sound so that you disconnect it. The digital multimeter has a large backlit LCD display. So,even if it is dark, you will clearly be able to see the readings without straining your eyes.
On top of this, it shows 3 times readings per second more than other other multimeters. Along with the multimeter, you get a 9V battery, user manual in english, 2 alligator clips, and 2 test leads.
It is an electronic instrument used to measure various functions in a unit. It is also called as ohmmeter, voltmeter or volt-ohm meter. In general, the standard multimeter is used to measure the estimations of voltage, amperes and ohms. While this digital multimeter will perform some extra estimations, which incorporate recurrence, capacitance, temperature, congruity and so on with its advanced and rationale innovation.
