Which multimeter is better to choose for the house: market overview and tips

Washing machines, hobs, fixtures and fans actuates the electrical current. Without this universal energy resource it is impossible to imagine modern apartment building. But we must understand that the most high-quality equipment can be disabled. To not address each time for troubleshooting the services of paid professionals, it makes sense to study the repair procedure. However, even the simplest recovery operations are not without suitable instruments. This article describes what the meter is better to choose for the house based on customer requirements and specifications for future tasks.

Which multimeter is better to choose for the house

Do not be afraid of difficulties when looking at the picture above with the working professional space electrician. Such protective equipment used when working with high voltage, which is not used in everyday life. The house is enough to observe basic precautions. In particular, do not touch the exposed wires. Measurement of electric resistance and other quantities operate without feeding feedingThat provides a high level of security.

However, the lower will be considered not only simple, but also professional measuring instruments. These devices have enhanced functionality. They are better protected from vibration and other adverse external influences. After studying this article, you will learn how to choose the best meter for the house to solve successfully the current and future challenges.

Classification

Devices of this type are designed to perform the following work steps:

• Measurement of voltage level, current.
• Checking the integrity of the contacts, "continuity" chains.
• Figuring performance semiconductor junctions in transistors and other devices.
• Measurement of resistance of the conductors, capacitors.

In this photo, the last - voltmeter V3-10A. He cited as an example of a good, but already obsolete product. It can be used to measure voltage in six different ranges (from 0,5 V to 300 V). Modern digital analogues of smaller, lighter, more convenient. They are designed to measure different variables. With a large display easy to read testimony.

But multimeters of this type in the new version used so far. Their main advantage - saving performance (individual function) without its own power supply. All digital devices are driven by the built-in battery, Batteries.

The fixed version release devices with improved accuracy for laboratory testing, scientific experiments, production checks.

Note! If you select the meter for a home with a minimum set of measurement capabilities, this is enough to solve common tasks. With such a probe is convenient to work in tight spaces.

The construction and use

In a typical instrument of this type input signal using the stylus is supplied to the selector. They selected measurement range, current, voltage, or other value. By proper circuit signal is fed to a dedicated chip. After processing the resulting value in a user form is displayed on a digital display. Most commonly used screens, liquid crystal, which differ in the minimum power consumption.

The following list shows the notation below:

• 1 - central switch;
• 2 - selected range when measuring AC voltage (750 V, or 200V) in this sector;
• 3, 4 - sectors with ranges of constant voltage (the allowable maximum of 200 mA and 10 A, respectively);
• 5 - is set in the slot connector (red) if the measured DC current with the greatest value of 10 A;
• 6/7 - zero / phase terminal;
• 8 - special connector verification transistors (n-p-nand p-n-ptipov);
• 9 - the position of "continuity test" to check the integrity of the electrical circuit;
• 10 - in this sector is selected resistance measurement range conductor;
• 11 - measuring the magnitude of the constant voltage sector;
• 12 - liquid crystal display.

How to pick up the equipment according to the target destination

Not to overpay, you must define a list of important criteria for a particular user.

built-in indicator light It lights up when the touch probe to phase conductor. Versatile multimeter is useful for a wide range of different operations.

Such equipment is used by amateurs and professionals to test, build, repair and settings various electronic circuits. In addition to accurately measure quantities with the integrated oscilloscope user may examine the shape of the signals.

This device is specially designed for use with vehicles. Long convenient probe for measurements in difficult locations. It was created without a sharp tip that is able to damage the skin cable to find the right wires in the wiring. Integrated lighting facilitates precise execution of individual actions.

The functionality of modern measuring devices

To determine the potential of the specialized equipment, it is possible to study in detail some models.

Multimeter DT 832 Instructions for Use

Assignment of control elements described above with the "younger" model DT 830. In this modification, a signal generator added.

This device with dimensions (height x width x depth in mm) 126 x 70 x 28 and a weight of 140 g is suitable for mobile operation. At economical LCD panel displays not only the measurement results, but also a low battery level. Overload protection is installed inexpensive fuse.

Important! It should be remembered that in the nest 10 A protective devices do not. Exceeding the maximum level measuring device spoil.

For each range, the manufacturer has determined specific tolerances and error:

The measurement is started by connecting the test leads to the appropriate jacks. First, choose a maximum range. Gradually switch down until the desired sensitivity. If the screen appeared the figure "1", an overload. Need to quickly move to a higher range. The electrical circuit continuity test mode audible alarm is triggered when the resistance is less than 1 kOhm.

To the device for a long time to keep working capacity, measurement is performed in accordance with the official manufacturer's instructions. Replacement of batteries and the failed fuse links operate only in position «Off» switch ( "OFF").

simple tester

When selecting the meter for the house, you can restrict the ability of the next fixture.

There is built in the housing Tally levels (from 12 V to 690V). Below - there is a miniature display. It is designed to display an indication, since even in the official manufacturer of store does not result in the exact values ​​of errors. For most everyday tasks of this functionality is enough. Good protection class IP 67 will prevent accidental damage is not too gentle treatment.

professional Products

These devices provide precision measurements with high precision, up to 6 decimal places.

This technique is able to detect temperature using remote sensor in the range from -200 ° C to + 600 ° C. It can be connected to a data network Ethernet. Acceptable software update, a record of information in the internal and external memory hook. It - equipment for professional laboratory use, it will not necessarily include the rating multimeter for home use. It only shows the maximum capabilities of modern instrumentation.

Note! Parameters multimeters Russian production is no worse than foreign analogues. When comparing devices allow for formal guarantees, the availability of spare parts, the development of a network of repair shops.

General conclusions

Based on these examples and recommendations are not difficult to make a decision about what is best to choose a multimeter for home use:

• For the "continuity" chains and determine the presence of voltage outlet enough to buy a simple tester screwdriver.
• If we assume a more complex operation, it is necessary to make a list of the required quantities. A suitable device is selected with the range and precision of measurements.
• Be sure to take into account the individual requirements to the size of the meter and its protection against external influences. Check ergonomics, equipment, audible alarm and other additional features.
• Radio amateurs need not only numeric values, but also information about waveforms. He is useful to a combined unit with an oscilloscope.
• If the test road network is expected, it is possible to purchase specialized equipment.

To find out what is best to buy a multimeter, reviews study together with other parameters. Especially valuable are the relevant recommendations of experts. To search for specific types of instruments and comparison shopping conditions Use standard Internet tools.
