Buyer’s Guide to Choosing the Best Volt Meter: Your Questions Answered
Our buyer’s guide to help you fully understand the important features you might want to consider when you’re looking to buy the best multimeter possible.
What’s The Difference between a Voltmeter and a Multimeter?
A voltmeter measures only voltage but a multimeter measures most, if not, all of the testing ranges. These include voltage as well as current, voltage, resistance, frequency, inductance, capacitance and even humidity and temperature.
There are two types of multimeters, analog and digital. Multimeters are obviously the more useful tester meter between the two measurement tools because of its multiple uses. But a voltmeter also has its uses so you may also consider getting it. Many people prefer the durability and old school functionality of an analog device. Analog multimeter represents to measure the value of power quantity. But the analog multimeters cannot use for a long time if it then damage the dial space with the buildup of inside dial pads.
What Voltmeters Are Capable Of
Keep in mind that volts are a unit of measure representing the difference in potential between the negative and positive nodes of an electric current. As such, digital multimeters measure said the difference in potential and provide the result in terms of volts.
Emphasis must also be made that some digital multimeters can work with both alternating and direct currents. But there are also some voltmeters that work only in ac current and some digital multimeters designed exclusively for direct current. Our 10 best multimeters on the market are obviously the ones that work with both types of current.
Digital multimeters measure voltage, resistance through a fine wire coil that carries current, the heart of these devices if you will. This wire coil hovers above an external magnetic field.
When the clamps or leads on a multimeter is connected to a power source, such as a plug or a battery, the electrical current from it flows through the wire coil. The current then reacts with the magnetic coil resulting in its spinning motion. The rotation can result in either a needle moving, as is the case for an analog multimeter, or shows a reading in the case of a digital multimeter.
What Are The Main Differences When Using A Digital Versus An Analog Multimeters?
The main difference between a digital and an analog meter lies in the way the readings are presented. With a digital meter, the numbers are displayed on an backlit lcd display, which may or may not have backlights for easy reading in low-light conditions. The large LCD display accurately displays current, voltage and resistance. With an analog meter, the values are indicated on a scale and deflection pointer.
Emphasis must also be made that digital multimeters are less likely to be affected by external magnetic interference. These also aren’t made with wire coils since these can increase damage. These are, however, less responsive to quick voltage changes because these update more slowly than their analog counterparts.
But in terms of accurate readings, digital multimeters give more precise voltage measurement functions than analog multimeters; the latter are prone to error due to their pointer-based technology. The readings on a digital meter are stated in numeric form while on an analog multimeter, it’s on a scale against a pointer.
As for calibration, digital meters have automatic calibration systems that make it faster and easier to make measurements. With analog multimeters, it’s manual calibration only. This is true for setting the range wherein most digital meters have an auto-ranging feature while analog meters require manual setting.
Other differences include:
ADC requirement
Analog multimeters don’t require analog-to-digital converters while digital meters require it. The ADC requirement is for displaying the readings on the screen.
AC frequency
Digital measures can measure higher alternating current (AC) frequency than analog meters.
Power supply
Digital meters require power supply while analog units don’t.
Input signals
Analog meters can only display a single input signal value while digital meters can accept multiple inputs. The latter also has adjustable displays for showing different input signals.
Due to the number of components necessary in digital meters and their complexity of construction, these are also more expensive than analog meters.
The Top Things to Consider When Choosing the Best Product
The first factor that should be make sure when choosing a multimeter is the choice between analog multimeter and digital. Keep in mind that each type has its pros and cons so it will boil down to your personal preferences.
On one hand, digital meters provide more precise readings and give better readouts through their LCD screens. These are also more compact, lightweight and portable aside from being equipped with more features for testing most, if not all, ranges.
On the other hand, analog meters have an old-school appeal to them that appeals to many professional technicians and electricians. These don’t require a power supply and can be used in rough situations.
The second factor is the choice between manual ranging and auto-ranging digital multimeter. The latter means that the multimeter can recognize the device being tested and, thus, there’s no need to input the range. You then won’t have to know the values beforehand since the multimeter will find them, in contrast with manual ranging where you must know the range of values (amps, ohms, volts), and input jacks for the test leads.
Of course, you should look into the level of accuracy of the multimeter. In an ideal world, it should always give 100% accurate readings even after several years of use. This isn’t obviously the case in all digital multimeters for many reasons, such as cheap components, imperfect processes and even user error.
Choose a digital multimeter with dual differential temperature function whenever you want recurrent thermocouple monitoring needs.
In general, the more precise the digital clamp meter and multimeter, the more expensive it’s likely to be because of the state-of-the-art components used, among other reasons. You will want a more expensive digital multimeter if you’re a professional technician or electrician who wants precise readings every time. But if you’re a DIY enthusiast, more affordable multimeter options are better choice since precise readings aren’t necessary.
Other factors that should be considered when choosing the Best Product
- The safety features, such as internal blast shields, wide flanges and shrouded banana plugs. Look into input protection and isolation slots, too. While these will add to the cost, these are essential for keeping your safe while working with electricity.
- The overall design and build quality should be ergonomic for ease of handling and sturdy for prolonged use in rugged conditions. Look for thick and tough casing and finish.
- You may also want to make sure the brand since some brands are more reliable than others. Fluke, for example, is a brand well-known for its line of reasonably-priced yet high-precision best multimeters on the market.
How Do I Operate A Multimeter/ how to use a multimeter?
- Be make sure to read the operations manual for the digital multimeter that you’re using as there may be differences between units. In general, however, these are the basic steps.
- Set the mode by using the dial.
- Insert the test leads on the appropriate colored slots (red and black)
- Be sure to check that your fingers aren’t in contact with the metal probes and the probes aren’t touching each other, too.
- Insert the metal test probes into the wall outlet. Basically, the negative test lead (black) goes into the outlet’s larger vertical slot while the positive test lead (red) leads to the smaller vertical slot. This is applicable on a 120V 15A outlet.
- Check the reading, which should be 120V. But if the display shows “1” or “OL”, then it may be necessary to increase the range

What Do CAT Levels Mean For A Multimeter?
The CAT levels refer to the measurement category specified by the International Electrotechnical Commission (IEC) for live electric circuits used in measuring and testing installations, appliances and equipment. These categories consider the total continuous energy at the circuit’s given point as well as the presence of impulse voltages.
There are four CAT levels, namely:
- CAT I for measurements done on circuits that aren’t directly connected to the mains.
- CAT II for circuits directly connected to low voltage installations, usually in households.
- CAT III for measurements done on building installations.
- CAT IV for measurements done at the primary source of low voltage installations, such as electricity meters and ripple control units.
What Are The Functions Of The Digital multimeter?
The digital voltmeter’s main function is reading the actual voltage of components including appliances, outlets and installations. The voltage can be measured in both DC and AC.
Other functions include automatic range selection, high input impedance and micro controllers. These devices also have no parallax errors. These useful functions are among the reasons for the increasing popularity of digital multimeters.

It has an 8-position dial selector, which makes it easy to choose the desired measurement, and seven buttons for the power switch, min/max, voltage range, and auto-hold, among others. Its response time is just as exceptional while its 400-hour battery life is welcome news; the battery can sit for prolonged periods without being drained.
Of course, its accuracy cannot be questioned! It will be accurate for several years so there’s no need for second-guessing the measurements even after it’s been in regular use for several years.
