Select the quality multimeter for home and work

click fraud protection
have self-respecting home worker must be a device to test all sorts of electric parameters.It can help you find a broken wire, check for voltage at the wall outlet or a battery lamp learn integrity, PETN, and other electrical and radio components.Digital electronic tester measures parameters such as AC and DC voltage, electric resistance, AC and DC current, temperature, frequency, inductance, capacitance, etc.In this article, we'll show you how to choose a multimeter and what is best for homes, jobs and cars.

the main criteria for selection

not every webmaster needs in use all the functions listed above, someone will be enough and more.would be enough to choose a simple multimeter-builder electrician, who will measure voltage, checks resistance, will ring chain.Therefore, to acquire an expensive tester does not make sense.

for electrical equipment, electrical equipment which serves to be beneficial to select the function "current clamp", which allows to measure the load on the operating equipment without interfering with the scheme.This in turn allows you to control and prevent accidents.

Bale masters are very helpful other functions associated with radio: ohmmeter, voltmeter, ammeter, measuring capacitance and inductance, frequency and so on.

Below we provide the most reliable models for each profession, and now I would like to touch briefly on the main points that you should consider when choosing a multimeter in 2016:

  1. Analog or digital.Digital course, sinceit has many functions and high accuracy.
  2. Functionality.This is what we have said and discuss in detail below, when will provide an overview of multimeters.
  3. Availability backlight and data hold button with them much easier to carry out the measurement.
  4. error operation may vary from 0.025 to 3%.The smaller the error, the better the tester.
  5. design.You have to choose the most convenient for multimer, focusing on its size, performance controls and other unimportant things.
  6. degree of protection from moisture, dust and shock.The higher the degree, the better the longer the tester and his life.
  7. Safety class.Another important selection criterion, which should definitely be paying attention.According to the standards, there are 4 classes: CAT 1 - it is possible to carry out measurements in low voltage networks, CAT 11 - supply networks, CAT 111 - distribution circuits in buildings, CAT 1V - distribution circuits outside of buildings.Protection can be provided by fuses (electromechanical) or more robust - electronic.Recommended to choose a digital multimeter with electronic protection.
  8. company.No less important factor, which should pay attention.Good producers of digital testers in 2016 are companies Mastech and UNI-T.

consider in the article, in our view, widespread and popular models of multimeters that can be selected for home, work and car diagnostics.

review the best models

DT-830B

DT- 830B with it should begin his acquaintance, if you never had the meter.An inexpensive device with a set of parameters that may be required for beginners and experienced electrician and handyman.

830

small size of the device, powered by a 9V battery krona.There is an LCD indicator, the function switch, the two probe red and black, three jacks 20A, V A Ω, COM to select the type of measurement parameters.As for features, the meter can measure:

  • DC with the range of 20 mA to 200 mA, as well as through a separate slot within 10A;
  • AC voltage up to 200V and up to 500V;
  • DC voltage in the range of 200 mV to 500V;
  • resistance to 2000 ohms;
  • diode test;
  • determination of the parameters of transistors.

Achilles' heel of this device is the wrong choice of measurement parameters.If you select continuity or resistance measurement and Gaugeable mains voltage tester fails.This model is very popular for home and is widely represented in our market.There are modifications of 830 models differ both in appearance and the presence of various functions.For more information, you can learn on the video:

Summarizing it should be noted that the choice of inexpensive multimeter is reasonable in the case, if it is used in electrical work on the house or onconstruction.

C266 (DT-266)

On the basis of the previous model, the measuring unit is collected not less than wonderful tester C266 (DT-266), which we also recommend that you choose.

K266

feature is the clamp meter and measure the lock button.When the check is going on in places such equipment, digital display disappears from view, or is not physically accessible, on the right side of the device there is a button that is fixed at the time of measurement and the result is not lost with the multimeter screen until the button is pressed.

Otherwise, he is not much different from the previous survey participants.It is often chosen for electricians.Structurally, it is more massive than 830 models.There is an LCD display and switch, three jacks for connecting probes, current clamps, switch and powered by battery krona.Depending on the company's products multimeter may differ in certain functional differences, the placement of controls and measuring ranges.

This instrument will measure:

  • AC voltage up to 750V;
  • constant 1000V;
  • constant current 20A;
  • 1000A AC, measure the "ticks";
  • resistance of 20 megohms;
  • to ring the integrity of the electrical circuit 200 ohms;
  • learn temperature using external thermocouple 750 ℃.

There is also a model equipped with a tester transistors and diodes, so if you need to work in the radio workshop of these features, you can choose a suitable multimeter.

M812

next member of our M812 review.Small but perfectly formed, it is about him.Swiss knife electrician, with small size and weight of 90 grams.This tester can easily fit in your pocket, it does not take up much space.This multimeter is deservedly popular with autoelectricians for repair and diagnostics of automotive equipment, so if you need a tester specifically for this, be sure to select the M812.

812

Structurally, it is made in the classical case and has a three-digit display, the mode switch, three jacks for connecting probes, as well as a connector for testing diodes and transistors.

M812 will learn such parameters:

  • DC and AC voltage within 500V;
  • direct current from 10 mA to 10 A, through an additional connector;
  • continuity audio signal;
  • resistance measured section to 2 MW;
  • check electronic semiconductor components;
  • presence of a signal generator to test the amplifiers and other radio.

If you want to choose a multimeter to auto or motorcycle diagnostics, this option is definitely worth considering.

DT9208A

next in our survey assistant for DIY and electrical DT9208A tester.If you want to choose a multimeter to 1000 rubles, the price and quality will be one of the best.

dt9208a photo

This meter serious looks.Large display with adjustable angle.Swing leg, through which the device can be positioned as convenient and informative about the user.The case is closed an additional striking cover, which performs protective functions.Large switch features two buttons: power and memory.This model is equipped with a shutdown timer.A useful feature that saves crown capacity and resource function switch.

In relation to the previously described testers, this unit has an extended measuring range.The body has four connectors for probes.DC voltage measurement range is divided into - 200mV, 2V, 200V, 1000V.For AC 750V, 200V, 20V.Current measurement range is divided into - 20 μA, to 20 mA, 200 mA, 20 A for DC and 200 mA, 20A AC.In addition, the meter allows for measurement of the resistance and continuity with the sound notification, check the p-n junction diode or thyristor.The measuring range is divided into the buzzer, 200 ohms, 2k, 20k, 200k, 2M, 20M, 200M.There is a function of the measurement of logical levels to test digital devices.It is also possible to measure the frequency range of 2 kHz and 200 kHz.

To check all kinds of converters and generators, the input impedance in the frequency mode is 10MOm, ie the effect on the measured circuit is minimal.Another advantage is a measure of the capacitors 2000 p, 20 n, 200n, 2 uF and 20 uF.Besides using DT9208A can check the temperature and check transistors. DT9208A better to choose a ham, asit has everything you need to repair the electronics.

MS 8229

last in our survey will combine all possible measurements MS 8229.
