These tools have improved so much that it requires no special technical knowledge to handle them. There is no need for a mortgage to buy one since technological progress has meant that testers of different price ranges ideal for all budgets came out on the market.

Why Use A Multimeter?

  1. Automatic Readings
  2. Tremendous Accuracy
  3. Auto-polarity Checking 
  4. Voltage Checking 
  5. Continuity Checking

Features to Consider When Choosing The Best Multimeter


The higher the category, the higher the protections the multimeter is equipped with. The product specifications that fall within CAT I are suitable for measuring very low currents, voltages, and powers.

To perform measurements on domestic systems, we need CAT II multimeters. Products marked CAT III are suitable for measuring panels, distribution sockets, and electric motors, while we use the CAT IV for high voltages and powers, such as those of industrial systems.


A multimeter offers all the measurements we need and maybe even some convenient extras. It is of fundamental importance that the instrument is accurate to return accurate measurements. Two parameters that determine the accuracy of a multitester are resolution and precision.

Frequency Measurement

The first important thing to test is precisely the range of measurements that a multimeter makes available to us. It must be suitable for the use we plan to make with this instrument.

They measure the frequency of a multimeter in hertz (Hz). It shows the number of complete turns of the circuit made by electricity in one second in AC circuits,

Energy Capacity

All multimeters are born as voltmeters and measure the electrical voltage or potential difference, both direct (DC) and alternating (AC). So, it is the measurement you will always find on any multimeter. There are two other measurements now extremely common, even in very low-end models.


When we talk about resolution referring to a multimeter, we mean the level of detail that this can achieve in the measurements. How many numbers after the decimal point it can show in the weakest detections and how many digits above the decimal point in the strongest ones.

Input Impedance

It measures the input impedance in ohms (Ω). It shows how much resistance electricity encounters in transit. We know that the analog multimeters have an impedance lower input to that of the digital multimeters. This impedance shows the sensitivity of the measured current. The higher the input impedance, the better the measurement of any voltage.

Range Limits

The electric current of a multimeter is measured in amperes (A). It shows the amount of energy passing through the tested circuit.

Temperature Measurement

Through the use of an accessory or integrated sensor often present in clamp models, the multimeter can measure the temperature of a device or an environment. You can always choose whether to use the Celsius or Fahrenheit scale.

Data Hold Functions

The key indicator of resolving a multitester is the number of digits that its display can show. The resolution is expressed in two ways as by counting the number of digits physically supported or by the maximum number the display can show. It does not correspond to the maximum potential given by the number of digits.

Safety Features

To understand how to choose a good multimeter, you must first take into consideration the current regulations on the safety of electrical equipment, and in particular the CEN EN standard of 61010. This standard has established four different categories of membership, identified by the Roman numbering I, II, III, and IV. They show the safety level of the instrument in sequential order.


It should be clear that what determines the validity of a multimeter for professional use is not the category it belongs to, but the level of accuracy of its measurements.

The cost of one of these instruments can vary from $20 to 4300 depending on the type, portable or bench, and the manufacturer. To influence the price, it is the characteristics of the device starting with the structural ones. Usually, portable models are the ones that cost less. But even in this case, there are price variations determined by the category to which they belong.

As far as portable models are concerned, the cheapest are those of category I-II that the price does not exceed about $50. For the units belonging to categories III and IV, they are much more expensive and their price can vary from $150 to $300 depending on the model and the manufacturer.

Different Types Of Multimeters

Hva Multimeter

Industry professionals in HVAC (heating, ventilation, and air conditioning) need specialized multimeters, just like the Fluke 117. For example, the Fluke 117’s built-in thermometer and micro-amp measurement function are ideal for HVAC applications. To keep costs down, Fluke has removed the high amperage selection from this model.

Auto-ranging Digital Multimeter

Auto-ranging multimeters will connect to the devices and come up with desired parameters. By doing this, you save yourself the hassle of having to know all the values ​​of resistance, capacitance, and voltage. This multimeter will find the right value for you.

Fluke Multimeters

If you keep going down, you’ll see the Fluke brand pop up multiple times. What can we say about it? It is one of the best manufacturers of measurement and diagnostic tools around. The company produces instruments with high-quality materials, and the Fluke 117 HVAC multimeter is no exception.

Analog Multimeter

In an analog multimeter, they then make the electricity absorbed by the circuit under test to circulate in the magnet, creating a field that gives the coil a rotary motion. They connect it to a spiral spring calibrated in such a way as to resist rotation.

The result of the measurement corresponds to the intensity of current required by the driving torque of the coil to equal or exceed the resisting torque of the spiral spring.

Digital Multimeter

Depending on the measurement to be performed, it is advisable to use certain types of the multimeter. Digital multimeters are more suitable for making measurements that require little electricity consumption. They have a higher input impedance than analog models.

Clamp Digital Multimeter

The automatic clamp multimeter allows you to test alternating current by opening a clamp. This compact unit contains a great intrinsic utility, it can store information. It will let you know when you have reached a point of maximum reading. The clamp-type can also automatically enter sleep mode to save your autonomy.

Manual Range Vs Auto Range

Auto-range Meter

Auto-ranging means that the multimeter can recognize what you are testing. So, there is no need to enter the measurement range manually. Just let the device do the work by choosing the measurement.

Manual Range Meter

However, the above feature is not possible with a manual ranging multimeter. There are preset ranges and to get a reading you need to know which range of values ​​the component falls under.

Digital Vs. Analog Multimeters

Digital Multimeters

To perform the measurement, the digital multimeter must absorb electrical energy from the circuit to be examined. And it is done through two cables with relative tips at the ends that apply to the circuit to close it and circulate the current. For the measurement of the Ampere, it is preferable to use the amperometric clamps as they offer greater safety.

Analog Multimeters

The analog multimeter uses the same operating principle as the galvanometer. It absorbs electrical energy from the circuit being tested, to perform the measurement. Like the galvanometer, the analog multimeter uses a permanent magnet inside which there is a coil free to rotate on the axis perpendicular to the magnetic field lines.

Top 3 Best Multimeter Brands

There is a lot of competition at the low end of the portable multimeter market, and there is no brand that dominates the others. Many big brand meters at this level are designed by other companies, usually Asian houses you have never heard of.

2. What is a wonderful quality multimeter?

The multimeter does not affect the category to which it belongs. We can classify portable models into one or more categories from I to IV. And the same goes for bench devices with the difference that in this case, the cost is higher even for models that fall into the categories I-II.

The quality of the test leads used for measurements affects the accuracy of the readings. Units supplied with the instrument accessories, if this is cheap, it’ll be of poor quality. Therefore, replacing them with higher quality ones can lead to a marked improvement in the performance of the multimeter.

3. What is the best cheap multimeter?

Cen-Tech Digital Multimeter is the smallest product. It is the cheapest and made of lower material quality.

4. What is the easiest multimeter to use?
