In this part of our guide, we’re going to look at some of these positive attributes. These are the features that you should be concerned about when choosing the best multimeter for your needs.

Considering how small this electrical measuring device is, it’s surprising just how much manufacturers can pack inside them. When you know the key characteristics to look for in a multimeter, you will be better able to find one that suits your needs perfectly.

Without further ado here are the top things you need to consider when buying a multimeter:

  • 1. Price

Although this is not the only factor you should consider, it’s still very important to know what your budget is so you can choose a multimeter that is within your price range. Multimeters range from one end of the price spectrum to the other, but when shopping, it’s important to keep in mind that you often get what you pay for with this type of product.

So while you may find some that are priced under $20 and some that are well over $200, there are other factors to consider before you reach for the best cheap digital multimeter.

  • 2. Number of Functions

It’s obvious that the more functions your multimeter can perform, the more useful it’s going to be to you. The odds are that even if there functions that you don’t use on a regular basis, you’ll still find a use for them at some point in the future. So when looking for the best multimeter for your needs, look for one that has a lot more functions than you actually require.

  • 3. Auto-Ranging

You have a choice between buying a model that has auto-ranging already built into it or one that requires you to do this manually. This means you would have to adjust the meter’s settings to correctly reflect the ranges that you’re taking readings in. We recommend that you try to purchase a multimeter that has auto-ranging capabilities.

  • 4. Testing Format

The testing format is the way that your multimeter calculates all the readings that you get while using the measuring device. Each of these formulas is too complicated for us to go into right now, but here’s a brief overview:

Full-wave Rectification – You will typically find us on lower-priced models and its ratings are fairly accurate. However, this is more vulnerable to inaccuracies such as those readings than its counterparts.

True RMS Technology– This testing format can be found in the pricier multimeters on our list. It is a lot more accurate than the former model and is much less subject incorrect readings. This is the type that is most preferred by professional electricians.

  • 5. Display

Multimeter products typically have two kinds of displays where you get to see the results of what you’re testing with the device. The majority of multimeters now have digital readouts which upgrade for taking the guesswork out of taking a reading. However, there are some multimeters out there that are still indicating the reading using a needle display.

  • 6. Ease of Use

As you are probably already aware, there is an astoundingly wide selection of multimeters that you can purchase in the marketplace. There are some that are well designed and easy to use, and others that are packed so full of features that it would take a rocket scientist to figure them out. You obviously want to go with one that is easy to use no matter how many features it has.

  • 7. Frequency of Use

The frequency with which you are going to be using your multimeter plays an important role when choosing the best one for your needs. It doesn’t make sense for you to spend tons of money on a device that you are only going to use once in a blue moon. On the other hand, for professionals who use multimeters on a daily basis, you need to make sure you get a best digital multimeter for the money so you can get accurate readings for a long time to come.

  • 8. Type of Use

This is yet another major criterion to consider in the decision-making process. What type of electrical testing are you going to be conducting with your multimeter? You have to put a lot of thought into this. For instance, if you’re mostly going to be testing amperage with your device, then it doesn’t make sense for you to buy one which doesn’t have this capability.

  • 9. Durability

Multimeters are often used in areas around the home or workspace that are pretty rough. This means you need to make sure that the multimeter you buy isn’t going to fall apart easily even if it accidentally drop it or bang it against a hard surface. The good news is, all the options on our list of the top ten multimeters available right now are durable and made from high-quality materials.

  • 10. Hands-free Operation

This is something that may not seem very important to a lot of people, but it’s a good idea to make sure that you get the best automotive digital multimeter with legs or other types of attachments that allow it to stand on its own on a flat surface but for the way when not in use.

What Is A Multimeter?

A multimeter is an electronic measuring instrument which combines many measurement functions into one convenient unit. It is also known as the multi-tester or a VOM. Typical multimeters measure voltage resistance and current. Analog multimeters have a microammeter that has a moving pointer which displays readings.

They are two main types of multimeter models, and these are digital and analog. A digital multimeter, also known as the DMM, has a numeric display and a variety of other visual cues that help to present the measurement readings. An analog multimeter, on the other hand, incorporates a microammeter which has a moving pointer to display the readings.

A multimeter is a standard diagnostic tool for any technician working in the electronic and electrical fields. Without one such device, there really isn’t much that an electrician can do safely. A multimeter also comes in handy for the majority of DIYers and can help prevent a lot off unnecessary accidents in the home and workplace.

This tool is very effective for supplying you with information concerning electrical measurements. These measurements can then be used to determine the cause of problems with a specific product or electrical line. The readings you get from it a calculated by simply measuring at least two electrical values. This is a must-have device if you want to safely work with electricity.

Different Types of Multimeters

Although the sensitivity range typically designates the overall purpose of a multimeter, this range can vary which means that the devices can also vary. In general terms, a multimeter is either analog or digital. However, there are some specific criteria that differentiate multimeters into further categories particularly for those looking for a specialized device.

For example, you might find that multimeters engineered for automotive applications aren’t usually able to effectively read our sources that have low voltage.

Here are the types of multimeters available:

  1. Digital Multimeters

Aside from the obvious reason, a digital multimeter differs from analog in that it has a much better overall accuracy and it also has the potential to download the readings to your computer. Also, the best digital multimeters have the added benefit of LCD screens that provide enhanced visibility. The readings are decimal readouts and they are indisputable. This is very different from analog versions.

  1. Analog Multimeters

This type of multimeter gives measurements that are significantly more difficult to read through the display. There is a decreased level of visibility and this type of device tends to be much less user-friendly. It is still good enough for professional use and it’s very durable. It’s also important to note that’s the readings that are recorded by an analog multimeter must be interpolated by the device’s user between the recorded accuracy and the marked numbers.

  1. Versatile Multimeters

Versatility is a great feature in measurement instruments, but when it comes to multimeters this isn’t such a good thing. That’s because a multimeter has to handle multiple readings but it tends not to have the right amount of sensitivity to be able to positively record some of the low range readings. A perfect example of this is an automotive multimeter due to its generic low-voltage recording of various power sources.

  1.  Oscilloscopes Multimeters

Multimeters that come with oscilloscopes allow you to make readings over time. They are extremely useful when figuring out if the equipment that is being measured gets fluctuations over a period of time. Both analog and digital multimeters can have oscilloscopes attached to them. However, it is generally only the digital models that give you the ability to transfer recorded data to a different device.

Functions of A Multimeter

A multimeter makes quick work of locating faults inside circuits. This type of device is generally handheld and extremely portable. You may find some multimeters on the market that are sold for as cheaply as 10 dollars while others are sold for a few hundred dollars.

The cheap ones obviously only work for basic applications, and they built with much lower quality which means that if you drop it or accidentally step on it, chances are you can kiss the device goodbye. It’s also important to note that the cheaper models sometimes give readings that are not very accurate. Having said that, they are some low-priced models that are actually pretty decent.

In this section, we are going to look at some of the functions of a multimeter, mostly with regard to reliability and sensitivity range. This includes both the best cheap digital multimeter options and the expensive ones.

  1. Temperature Sensor: This measures the temperature of the device being tested. It’s a feature which is ideal when it comes to controlling temperature-sensitive circuits or hardware.
  2. Capacitance: This function measures the system’s capacity for storing electric charge. It is mostly found on multimeters of the digital kind, particularly the high-end models.
  3. Auto Range: A multimeter with this type of function can easily be adjusted automatically depending on the measurement range of the measured inputs. This feature allows you to save time if you’re running multiple tests.
  4. Display Rate: Amultimeter’s display rate is a representation of the speed at which the image is refreshed by the digital display. A multimeter with a faster display rate gives a slightly more accurate reading thanks to its convenience.
  5. Transistor Testing Circuit: If you’re buying a high-end multimeter, it needs to be able to easily check if the transistor is working as part of a larger electronic assembly or circuits. This feature will allow you to test integrated circuits and digital logic circuits of any kind.
  6. Holds Function: Every quality multimeter should have a holds function that keeps the display from deleting the readings on the screen. This can be really useful if you have to write down multiple readings.

How To Use A Multimeter

As previously mentioned, electrical multimeters display readings by measuring various electrical values. They do this when multiple things on the device itself are put in place. Typically you’ll find a set of testing prongs that you plug into the device, which then gives the meter the electricity it needs to give a reliable readout.

The meter, depending on the type, has a dial that you turn so that you can position it for the type of electrical reading that is being taken.

When you touch the test prongs against the points along an electrical line and once the current travels back to the multimeter, it tells you the value of the particular electrical traits that you’ve set the multimeter for. The value appears on the easy to read digital screen that is built into the multimeter.

When it comes to using a multimeter, it doesn’t matter if you’re a pro or if you want to use it for odd jobs around the house. The most important thing is to get a multimeter that is easy to read and use no matter how many functions it has. After all, there is no point in buying an expensive gadget with 1001 functions if you won’t be able to use any of them effectively.

How To Test A Capacitor With A Multimeter

Testing a capacitor using a multimeter is not a very complicated process at all. You can either use an analog or digital multimeter. To test a capacitor using an analog multimeter, just follow these steps:

  • Ensure that the suspected capacitor has been fully discharged
  • Take your AVO meter and select analog meter on OHM
  • Connect meter leads to capacitor terminals
  • Take note of the reading and then compare with the following results

Short Capacitors: shows very low resistance

Open Capacitors: doesn’t show any movements

Good Capacitors: shows no resistance which gradually grows towards the infinite’s

The second method is to check a capacitor using a digital multimeter. To do this all you need to do is follow the steps below:

  • Ensure that the capacitor is fully discharged
  • Set the meter to OHM range
  • Connect meter leads to capacitor terminals
  • The digital meter will show some numbers for instance. Take note of those numbers.
  • Immediately, it will return immediately to the open line (OL)

Each attempt of the second step will display the same results as in step four and five. This means the capacitor is in great condition. However, if you don’t see any change, it means the capacitor’s dead.

FAQs: Frequently Asked Questions About Multimeter

Q-1: What’s the difference between the Peak and Min/Max modes on a multimeter?

  • As its name implies, the Min/Max mode is simply the highest and lowest readings measured by the multimeter from the time that record mode began. To get a more accurate reading, the measured signals’ minimum and maximum needs to be typically between 200 and 350 milliseconds or longer.
  • They work on any mode including volts DC, resistance, true RMS volts AC, as well as current functions. Peak mode, on the other hand, measures the peak voltage of a signal, both positive and negative. For a 120V AC line, the peaks are going to read +169v and -169 V. As a general rule, they’ll work for any peaks over 250 microseconds.

Q-2: Why do I need to use a multimeter?

  • There are two main reasons why people use multimeters. One has to do with safety and the other diagnosis. Working with electrical equipment can be very dangerous, and accidents could lead to fatalities if you’re not careful. A lot of professional users and DIYers always have multimeters on hand to check that there is no power coming to electrical lines or devices to ensure they can be worked on.
  • As for diagnosis, the multimeter gives you information that not only keeps you safe while you work around electricity, it also helps you to diagnose electrical problems. A multimeter will show you where there’s no power so that you know where the problem is by performing a variety of tastes and then interpreting what the readings mean.

Q-3: What electrical properties can you determine with a multimeter?

  • A simple digital multimeter will show you many different electrical measurements. Some of the most commonly measured electrical properties are ohms, which are used for determining how much electrical resistance the ease in an electrical line.
  • A multimeter also measures the voltage which is also known as electromotive force. This is measured by checking the potential charge on two points on a device or along an electrical line. You can also use a multimeter to check amps, which is the amount of current flowing through the electrical line at the moment of measurement, as well as the temperature of a device.

Q-4: Are they any safety tips for using multimeters?

  • A multimeter by its very nature allows you to work around electricity safely by helping you determine if there is electricity flowing through the line or to the device. But, as with any other device, if you don’t use it properly it can also be unsafe. In order to use the multimeter safely, they are some safety tips that you should follow.
  • First, always take your reading by holding the ends of the electrical probes using one hand if possible. This greatly reduces the chance of an electrical shock that passes through vital organs. Another safety tip is to never assume that you multimeter working properly. Make sure you inspect it before use and don’t proceed to work on something if you don’t get a reading with your multimeter.
