Computers and modern gadgets

A multimeter is a modern electrical measuring device that performs the functions of an ammeter, voltmeter and ohmmeter, so it can be used to detect faulty electrical wiring in an apartment or deal with the breakdown of any electrical household appliances. With such a tool, anyone can check the performance of lamps or the serviceability of lamps, as well as test the electrical parameters in the house. There is no need to buy expensive power tools for use at home. You will learn which multimeter is better to choose from this article.

Introduction to the Multimeter

First of all, we will look at the purpose and design of this device, as well as how to use a multimeter.

So, a multimeter is a multifunctional measuring instrument, also called a universal tester. With its help, you can find out the values ​​of resistance, voltage and current in a section of the circuit.

In addition, using a universal tester, you can check the integrity of the electrical circuit and many radio components (for example, transistors or diodes). Functionally, the multimeter replaces several measuring devices: voltmeter, ammeter, ohmmeter. It is very convenient to have such a compact device that can measure almost everything.

From this we can conclude that any person who has at least once in his life repaired electrical products, even at home, will find it useful to know which multimeter to choose for his home.

    The wide range of these devices is divided into two main types:
  1. Analog.
  2. Digital.

A few years ago, only analog devices were used, but at the moment it is considered much better. In addition to being quite convenient to use, they are even more accurate in their measurements.

If you are deciding which multimeter is preferable to choose for everyday use, opt for the digital version.

An analog device is much more difficult to use. It is completely unsuitable for people suffering from myopia, however, with good vision, such an instrument can be purchased for use at home.

Appearance

Now let's look at the appearance of the multimeter, and for a complete understanding of what we are talking about, here is an image in which everything is shown schematically.

As you can see, below the LCD display there is a multi-position switch. There are eight sectors around it, and the position of the switch determines what measurements can be made. Let's look at all the sectors clockwise:

  • Central top position OFF – the device is turned off;
  • The ACV position allows you to measure AC voltage;
  • DCA – in this mode, the multimeter measures direct current;
  • In the switch position at the 10A mark, large currents are measured - up to 10 amperes inclusive;
  • hFE – transistor continuity. There is also a multifunctional connector for these purposes, which allows you to easily check soldered transistors.
  • The next sector (indicated as an arrow with a plus sign) allows you to test the integrity of the electrical circuit;
  • Ω – in this position the multimeter acts as an ohmmeter;
  • To measure DC voltage, the switch is set to the DCV position.

Now you know all the positions that are on the front panel of the multimeter and what they are designed to measure.

Main functions

The appearance of an inexpensive multimeter is shown in the picture.

The DCV (=) area is located in the upper left corner. By setting the switch to this range, we can measure DC voltage. For example, a battery, an accumulator. It is worth keeping in mind that all measurements should be started by setting the switch to the maximum value.

In this case, it is 1000 V. Naturally, when measuring the voltage on a battery, we know that the voltage there cannot exceed 10 V, so we can safely immediately set the range to 20 V. By setting a range closer to the actual value, we get a more accurate reading from the device.

The voltage between should be 210-240 V (voltage in the socket), in the case of measuring the voltage between phase conductors - about 400 V.

The next DCA (=) range is DC current measurement. To measure current, you need to connect the probes to an open circuit. Keep in mind that if the current is more than 200 mA, you need to move the probe into a special socket (10 A) and turn on the switch to 10 A. This function of the multimeter can measure the battery current.

hFE – transistor testing mode. We don't need it in everyday life.

TEMP (may be present) – temperature measurement using a special probe. Show off a cheap multimeter :) I don’t know why this function is even needed there. It is possible to measure the temperature of a soldering iron tip or solder. My multimeter has this function.

Checking diodes and continuity is a very useful function of a multimeter. Allows you to find breaks and short circuits in an electrical circuit. If you take any conductor and apply probes on both sides, the multimeter will ring, thereby signaling the integrity of the electrical circuit.

If there is a cable and wires of the same color, then you can easily determine which wire is which.

Resistance measurement. Here I think everything is clear. This option is more suitable for measuring resistance in electronics.

The main problem is the presence of three connectors for connection, while there are only two probes themselves. Therefore, before you start using a multimeter, you need to correctly connect the test leads.

In fact, there is nothing complicated. The black probe (zero or minus) is connected to the lowest connector, designated COM. This connection is suitable for all measurements and is permanent.

The red (positive) probe is most often connected to the middle connector, designated VΩmA. This connection scheme allows you to make almost all measurements. The upper output, marked 10 ADC, is used to measure currents above 200 mA: in this case, a probe with a red wire is inserted into it.

Before you start using your new multimeter, you need to insert a 9V Krona battery into it. To do this, you need to remove the back cover and, observing the polarity, connect the two wires to the battery contacts, and then install it in the designated slot.

How to measure

Now you are ready to start using the universal tester.

An important nuance of any measurements using a universal tester is the fact that when carrying out any measurements, the rotating knob must be set to the maximum value so as not to damage the electronics.

Then, if the readings are lower, the knob is moved to lower levels to get the most accurate measurement results.

Now let's look at how to make basic measurements with this device.

We measure the voltage

This type of measurement is one of the most popular in everyday life: it is often necessary to check the size or charge of the battery. Let's take a closer look at how to perform such manipulations.

To measure the voltage in the socket, the switch must be in the ACV sector, at the maximum mark, in this case, it is 750. Then, carefully holding the probes by the insulated handles, we touch the different contacts of the socket with needles.

The display will display the results in volts. In the same way, you can measure the voltage on a lamp or other household appliance. You should remember the safety rules and do not touch exposed areas of electrical wiring with your hands.

To measure DC voltage, for example, when repairing a car's electrical system or battery, the rotary knob of the multimeter should be in the DCV sector. When working with a battery, it is enough to set the knob to the 20 volt position to get accurate readings.

To take measurements, you need to touch the battery contacts and take readings. Polarity matters in that when connected in reverse, the values ​​will be with a minus sign.

In the same way, you can take measurements from any part or wire of the vehicle’s on-board network. The same technique is used to find out the charge of a AA battery.

Also a useful function for everyday use is checking the resistance.

    This is done in the following order:
  1. The circuit in which measurements need to be made is disconnected from the power supply. This is necessary so that the tester readings in ohmmeter mode are not distorted.
  2. Then the switch is placed in the Ω sector at the approximate value of the resistance that should be in the circuit (according to the passport or technical specifications).

The ability to use a multimeter in ohmmeter mode in everyday life will be useful for measuring the resistance of failed electrical appliances, especially those containing heating elements. Thus, you can determine whether the heating element needs to be replaced or the cause of the breakdown is different.

Dialing mode

This mode is also quite useful even for “dummies”: with its help you can find an open circuit in any circuit. The most common method used is to search for dialing: both home and car. To enable the continuity mode on the multimeter, the switch is placed in the sector designated diode.

Before you start looking for a break, the entire circuit is de-energized, and the probes for checking the multimeter are short-circuited with each other - a sound signal should follow, indicating that the device is working. After this, you can begin to search for an open circuit, ringing small sections one by one.

What criteria should you follow when choosing a multimeter?

When approaching the idea of ​​buying a multimeter, you need to identify the necessary selection criteria, and this, as a rule, is the price of the device and the tasks for which it is purchased.

If the device is required for the home, for a car, or for infrequent use, then an excellent option would be some kind of low-budget, basic-level multimeter so that, if necessary, you can quickly take readings, determine, or calculate how much charge is left in the battery.

Such multimeters can be found at Resanta, Elitech or bought on Aliexpress.

It will be convenient for specialists to have a multimeter with advanced functionality. You need to pay attention to the additional features provided in order to know whether they will be useful in practice.

If you need to work with electrical installations, high precision is required, and professional devices that diagnose a wide variety of faults are suitable.

Which device to buy depends on what goals you are pursuing.

    In this case, it is worth proceeding from the following criteria:
  • Ease of use. This is the most important condition. All other criteria are not so important if you constantly experience discomfort when working with the device. If the device is uncomfortable to hold, the readings are difficult to see, and the plug is difficult to get into the socket, the work begins to irritate.
  • Functionality sufficient to solve your problems.
  • Possibility to illuminate the display panel. An electrician often works with the lights turned off. Each time moving the flashlight from the wires with attached probes to the indicator and back is simply dangerous.
  • There is a button for storing the measured value, which is very convenient - you don’t have to write down or remember the readings.
  • Moisture-, dust- and shock-proof. Measurements often have to be taken in extreme conditions - in a damp basement or dusty attic, and it is often only a matter of time before the device falls onto a hard floor. If it has good security indicators, you don’t have to worry about operation.

Protection can be electrical or electronic. Electrical protection is just a fuse, while electronic protection is more reliable, and you don’t have to disassemble the device to replace the fuse.

The accuracy of the readings is important, but not critical. Most work with a multimeter is simply checking the presence/absence of contact or determining the serviceability of an element.

Brand. The de facto standard is devices from UNI-T and Mastech.

In general, it is better to purchase an inexpensive and simple digital multimeter. Even with the minimum configuration, its capabilities are enough to perform most of the work related to electricity - checking the charge of the batteries, the health of the wiring, the voltage in the socket/at the battery terminals, and so on.

Expensive and complex multifunctional models are really only needed by professionals - those who regularly perform critical work with electrical equipment.

Parameters for selecting a device

When choosing a multimeter for your home, consider important characteristics. For example, the price of the device and the manufacturer are important. Another equally important parameter is the bit depth, which displays the number of digits after the decimal point. Slight error may exist in products purchased for home use.

More careful measurements are necessary in specialized equipment. The measurement limit is of no small importance. These are the upper and lower parameters that the multimeter displays. The indicator hold button and backlight will make using the device much easier.

Conditions in which the device will be used. Depending on the place of use, you can wisely select a multimeter with the required degree of protection. For example, with protection from dust or moisture.

Functional. You need to pay attention to the necessary options of the device and not give up those that protect the device from overloads or make using the multimeter more comfortable. This way, the display backlight will not be superfluous at all, especially if you use the device in a place where there is no normal lighting.

Equipment. If the box with the multimeter contains it, it will be very convenient.

The degree of error of the device. If you buy a professional multimeter, then its error should be minimal and be approximately 0.025%. If a multimeter is purchased for home and household needs, then 3% error will be a normal figure.

Measuring range. At home or for a car, multimeters with a minimum range of standard parameters will be quite successful. If the device is purchased for professional purposes, then the approach is different. The wider the range for each measurement, the better.

Selecting a security category

An important point in the selection process is an accurate understanding of how much voltage you will have to work with.

    There are 4 electrical safety categories in total:
  1. “CAT I” – designed for low-voltage networks and standard office equipment (telephony, alarm, printers, copying machines).
  2. “CAT II” – for voltages up to 500 Volts and for testing equipment designed for single-phase networks, including construction power tools and household appliances (hammer drills, washing machines).
  3. “CAT III” – for three-phase networks and three-phase equipment (household electricity meters, industrial machine motors, welding machines, single-phase lighting lines).
  4. “CAT IV” – for work with overhead power lines, underground cables, industrial electricity meters, transformer substations.

You should understand the difference between the electrical safety category of a multimeter and the rated permissible voltage. The higher the safety category, the lower the risk of electrical injury, even if a device with category “CAT I” says “up to 1000 Volts”, and a device with category “CAT IV” says “up to 500 Volts”.

The closer your place of work is to a transformer substation or to a power line, the higher the category of the multimeter should be.

To ensure that such a tool does not let you down, you need to carefully study its properties before purchasing. First, you need to outline the required list of multimeter functions. A lot depends on the tasks for which you are buying the product.

So, if you plan to use it only at home to measure the voltage in the network, check the electrical circuit, or the battery charge level, then there is little point in buying professional multimeters with a huge range of auxiliary capabilities.

Most people believe that to choose a digital model of acceptable quality, you must look at the country of origin. This opinion is not always correct, since the guarantee of good performance and the main part of the entire product is the microcircuit, the quality of which is quite high.

In addition, when choosing, you need to take into account the quality of the multimeter case, and at the same time the reliability of the switching parts in the tool set, for example, such as contact probes. On inexpensive models, they are most often made from cheap raw materials, and therefore break quickly.

It's a good idea to check the multimeter's certification. There should be a Rostest logo on the back of the device casing. This is some guarantee of quality and indicates that this device can be distributed throughout our country.

When answering the question of how to choose a multimeter, the very first thing that comes to mind is the degree of error. This term defines the deviation of the displayed result from the measured one. The error is indicated as a percentage; it is preferable that it should not be more than one, maximum one and a half.

In addition, we must not forget that the accuracy of measurements of different quantities or instruments varies, but for using it at home this is not of fundamental importance.

When choosing a multimeter for the home, in addition to everything else, they also take into account the maximum measurement value. This is the highest limit of resistance or voltage measurement that the device can display.

In addition, you need to pay close attention to the quality of the multimeter display.

What is the difference between a multimeter and a tester?

People often confuse a tester and a multimeter, mistakenly believing that they are the same thing. Actually no. Multimeter is more multifunctional than a tester. Using a multimeter you can measure a wide variety of parameters.

Well, a regular tester has several diodes on its panel, thanks to which you can find out the voltage value. It also has a phase indicator, and it is possible to check the integrity of the circuit.

    It is believed that an analog (arrow) multimeter is an outdated model of a measuring device, because digital has a number of advantages:
  • Measurement accuracy. This is due not only to the stability of the microcircuits, but also to the fact that when reading the results from a dial multimeter, your eyes must look at the display strictly at an angle of 90°, which is not always achievable.
  • Additional functions. In the analog version they are absent as a definition; digital multimeters are always equipped with additional options and computational processes.
  • Does not depend on polarity. The digital tester will show all the necessary data for any connection. If the polarity is reversed, a minus sign “-” will appear before the result. In an analog multimeter, the needle will deflect to the left until it reaches the limiter.
  • Resistant to damage. A digital multimeter can fall off a desk, be stored in the bottom of a shopping bag, and still remain a highly accurate instrument. The analog counterpart is more “capricious” and requires careful handling, because contains in its design moving and very finely calibrated parts.
  • Independence from battery charge. Both analog and digital multimeters operate on batteries, however, when the batteries in the pointer device are discharged, it is necessary to periodically adjust the “zero”.
  • Digital does not need such calibration. An analog multimeter lasts about twice as long on battery power, but considering that a digital one also lasts six months from one set, this figure is not particularly relevant.
  • In general, analog multimeters are only used in specialized appliance repair shops or laboratories. Unlike digital ones, they show instant changes in indicators.

Choosing a multimeter for home

For the vast majority of home craftsmen and professional electricians involved in the repair and installation of electrical networks inside apartments and houses, the characteristics described below will be sufficient.

Country of origin and price. Most digital multimeters are equipped with all the necessary options, regardless of price and country of manufacture. Not counting, of course, the cheapest Chinese counterfeits. Anything that starts from $5 is, in most cases, a quality product. For example, the Latvian Resanta DT 838.

Bit depth. Those. how many digits after the decimal point the device will display when measuring. For example, the fluke 106 multimeter will show three digits (up to a thousandth), but the Resanta DT890B will only show two (up to a hundredth). For most tasks around the house, two decimal places are sufficient.

Error. If you plan to use the multimeter at home and for measurements related to electrical connections, the standard accuracy of a digital multimeter will be sufficient.

For example, Resanta DT9205A produces from 0.5 to 2% error depending on the measured parameters. For more accurate measurements, you should use specialized equipment, such as an analog multimeter.

Measurement limit. This number is also indicated on the device itself. Shows the limit (upper and lower) values ​​that are perceived by the multimeter.

    To complete most tasks you will need:
  1. Constant voltage from 200 mV to 1000 V;
  2. Variable voltage from 200 mV to 700 V;
  3. Resistance from 200 Ohm to 200 MOhm;
  4. Current strength from 2 mA to 20 A;

Rating of digital multimeters - from home electrician to professional

  • Multimeter type "M812"

The easiest choice for the home and garage is the M812 type multimeter. It is very small and light (about 90 grams), so you can easily put it in your shirt pocket. It can easily be kept in a toolbox under the saddle of a moped.

But, despite its modest size, it has all the necessary functions: a “dialer” with sound, a voltmeter up to five thousand volts (both direct and alternating voltage), as well as a built-in audio frequency generator to determine the performance of amplifiers.

  • Devices marked “DT-83*” (“M-83*”)

Suitable for novice electricians. They have the necessary functions for measuring voltage, resistance, current, as well as sound “continuity” and checking semiconductor parts. Some additional functions present in other multimeter models are not available.

The disadvantage of this model is insufficient security against errors. So, when choosing a measurement mode, the incorrect position of the disk or a mismatch in current/voltage may damage the device. But all the minor shortcomings are made up for by the very affordable price of the device.

  • Multimeter “DT266” (“S266”)

Such models are a logical development of the previous design. This is a semi-professional device, the capabilities of which are often enough for professionals.

The main difference from its predecessors is the presence of a current-measuring “claw”, which allows you to measure current parameters without directly touching the conductor. Therefore, the weight of the device is naturally somewhat greater.

The kit necessarily includes a thermocouple for determining temperatures up to 750 degrees Celsius. Another plus is the button for recording readings; while it is closed, the maximum value remains on the display.

However, many “266” models do not have the ability to determine the health of transistors and diodes (this is still more of a tool for working with electricians, not electronics), so make a choice based on your needs.

  • "DT9208" and its modifications

They are, perhaps, the best in their price category up to 1000 rubles.

    The designers of this model clearly tried to create the most comfortable conditions for taking measurements:
  1. The scoreboard can be tilted towards or away from you.
  2. There is a special folding leg-stand so that you do not have to hold the device in your hands at an angle all the time so that the readings can be seen.
  3. The perimeter of the case is covered with a soft and rough protective case of bright color, so that even in the dark you can quickly find the device if, for example, it falls out of your hands.
  4. The markings on the body for the circular variator are painted in different colors to make it easier to navigate which mode is currently on.
  5. If there is no measurement for a long time, the device turns off automatically, saving energy.
    Button for holding readings during measurements.
  6. There is an additional fourth connector for the probe, placed separately - for measuring current strength of the order of milliamps.
  7. There are sockets for testing thyristors, diodes, capacitors and transistors.
  8. You can measure the logical signal level - for digital devices.
  9. Frequency meter from 2 kilohertz to 200 kilohertz.
  10. Thermal sensor directly in the device body plus an external thermocouple.
  • Models type "MC 8229"
    These are more professional multimeters that have all of the above advantages with the addition of the ability to measure:
  1. lighting;
  2. sound volume;
  3. air humidity.
    Also, most professional multimeters have the following differences:
  • can automatically select the measurement limit;
  • have overload protection in all measurement modes;
  • report an overload by showing “OL” (OverLoad) on the indicator panel;
  • warns about incorrect connection of probes;
  • have a multi-line display for comparing readings;
  • warns about the imminent discharge of batteries;
  • have an additional fuse with a self-recovery function.

Combines of this kind are used not only by electricians, but also by labor safety inspectors to measure noise, light, and humidity in workplaces. The price for them, naturally, is quite high - about 100 dollars.

When deciding which multimeters are best to choose for your home, you should consider this option. C 266 is assembled on the basis of the dt 830 device. A distinctive feature is a button for storing measurements and special clamps for measuring current.

A button that can be pressed to record certain data is located on the right side of the device. This type of device is in demand among electricians.

The device consists of an LCD indicator, sockets for probes and a switch. Designs may differ in some features.

    The product will allow:
  1. measure AC and DC voltage;
  2. current and resistance;
  3. determine the strength of the chain;
  4. find out the temperature.

A diode and transistor tester is also provided. The model is suitable for radio workshops.

The DT 9208 A equipment will be a good help in household chores. You can purchase a Russian-made multimeter; this is a good option in terms of cost and quality.

The device is equipped with a large indicator and a folding leg. There is also a function switch with memory and power buttons. This model has a timer and a function that saves the resource of modes and crown capacity.

The device also includes an expanded measurement scope. It can be used to measure circuit continuity and resistance.

When wondering which multimeter is best to choose at home, you can consider this option. Using this device you can determine the level of sound, light, temperature and humidity.

    MS 8229 has the following characteristics:
  • overload protection;
  • the presence of a sound and light signal if the wires are connected incorrectly;
  • The LCD display displays three readings at once;
  • can operate at an altitude of 2 thousand meters;
  • auto shut off function.

This device is suitable for professional craftsmen who repair electronic equipment.

What to choose from the Mastech product range

Many models are produced under the Mastech brand in the price range from $10 to $100.

The company offers a full range of measuring instruments - from cheap and simple analog devices for those who are accustomed to determining readings by arrow, to the stationary desktop model “Mastech MS8050”, which has laboratory measurement accuracy, software adjustment of measurements and the ability to transfer measurement results to a computer.

For everyday tasks, the DT830 digital multimeter is quite suitable, the price of which is about 3 US dollars.

    Its advantages are:
  1. overload protection;
  2. indication of low battery charge;
  3. sockets for testing semiconductor devices - transistors and diodes;
  4. warning sign “NV” when measuring the maximum permissible voltage values.

Mastech also offers an interesting model of a lightweight and convenient “pencil” type multimeter probe “MS8211D”.

    Its advantages:
  • miniature size and light weight;
  • built-in overload protection;
  • electrical safety category “CAT II 600 V”;
  • automatic power off (after 15 minutes of inactivity);
  • sound “continuity” of circuits;
  • the ability to turn off/switch operating modes with the thumb of one hand;
  • the tip of the probe on the body can be hidden inside by rotating the dielectric tip;
  • mode for storing the last and maximum of the measurements taken;
  • durable carrying case with a Velcro flap and a special strap for attaching to a mounting belt;
  • The crocodile connector is hidden inside the insulating tube.

In addition, this model is capable of checking the signal state of logical elements. Under the green plastic ring framing the tip of the probe, the LEDs are lit: green – logical “0”, red – logical “1”.

Which company is better

Which model is better to buy

Models of multimeters are divided into stationary and portable. Stationary multimeters provide an excellent range of capabilities, while portable ones are very convenient due to their mobility.

In addition, these devices can be divided into two more types: analog and digital. Analog multimeters are called pointer multimeters because their internal structure is a pointer magnetoelectric measuring device. The measurement results can be observed on the measuring scale along which the arrow moves. This type of multimeter is popular due to its budget price.

Digital multimeters have a special screen that shows the results of the measurements taken. These devices are the most accurate and fairly easy to use, but their price will be significantly higher. Based on these types of models, you can determine which model will be more acceptable.

Parameters for selecting a device

  • Conditions in which the device will be used. Depending on the place of use, you can wisely select a multimeter with the required degree of protection. For example, with protection from dust or moisture.
  • Functional. You need to pay attention to the necessary options of the device and not give up those that protect the device from overloads or make using the multimeter more comfortable. This way, the display backlight will not be superfluous at all, especially if you use the device in a place where there is no normal lighting.
  • Equipment. If there are current clamps in the box with the multimeter, then this will be very convenient.
  • The degree of error of the device. If you buy a professional multimeter, then its error should be minimal and be approximately 0.025%. If a multimeter is purchased for home and household needs, then a 3% error rate will be a normal figure.
  • Measuring range. At home or for a car, multimeters with a minimum range of standard parameters will be quite successful. If the device is purchased for professional purposes, then the approach is different. The wider the range for each measurement, the better.

What is the difference between a multimeter and a tester?

People often confuse a tester and a multimeter, mistakenly believing that they are the same thing. Actually no. A multimeter is more multifunctional than a tester. Using a multimeter you can measure a wide variety of parameters. Well, a regular tester has several diodes on its panel, thanks to which you can find out the voltage value. It also has a phase indicator, and it is possible to check the integrity of the circuit.
