How to be twisted with an indicator twist: thin in the middle

Sometimes at the house, the apartments are blamed for folding, connected with electrical wiring with electrical appliances. Schoraz viklikati to himself an electrician will not be handy, that one is expensive. In case of this, you won’t start a sensation in yoga, so as a problem, which is even more often, you can fix it with your own hands, even if the stench is due to minor damage in the electrical circuit, vimikachi or rosettes. But to know that solve the problem, you need a special tool - an indicator spin.

Indicator spins

Such a twist can be given to the rich by the unknown, and it is not necessary for the needs of the household. And yet, as you grow up with її possibilities, you will become an indispensable subject of your home screen with tools. And our article will help you to find out in particular the indicator spins.

What are you

In order to zastosovuvat be-a kind of tool for recognition, it is necessary to understand yoga attachment and the principle of work. Cost of indicator (signal) twists. The stench of the call predicts the zvichaynі models. Ale, with tsomu, there is an indicator on it, which shows the presence of the struma in the lance. Himself wine and giving the name of the building. Indicator twist can replace a multimeter. If you won't, it will cost you much cheaper for a vimiruvalny fixture.
In simple words, this virib is an indicator of tension, preparations for a visible twist. Today, so many are released from the great crowd. When tsmu їm vsіh characteristic zagalniy principle of work.

Get respect! Irrespective of the single principle of work, such virobi can grow among themselves with a form of vikonnanny, as well as we will add.
Let's take a look at the common standard and the simplest indicator twist.

Budova indicator twist

Here є dosit simple bud_vlya:

• sting, as if acting like a guide;
• thyristor. A sting connects to the new one. This element of the appointment of a decrease in the strength of the struma is equal, which will be safe;
• svetlodiod. Vіn roztasovaniya after thyristor. Svetlodiod comes to the contact fields, placement on the ends of the twist.

All the elements of the indicator twist are placed at the openings of the body made of plastic. Lights of the light of a person can easily bleed the light of the light, also protected under the plastic case.
Such a budova is typical for the simplest and the cheapest voltage indicator. With this help, you can determine the working phase. This situation has a zero in this situation.
Now let's take a closer look, as if to practice with such a twist.

Algorithm of work with simple voltage indicator

Since we have looked at the simplest signal twist, it is necessary to designate the correct robot algorithm for it. Check the phase of the wires, in this situation, looking like this:

• with a sting, it is necessary for the stinger to hit all the darts;

Twisting in working mode

• pіd h dotik to drotіv nebhіdno torkatisya contact field. It is specially designed for a plastic case;
• at the moment the dotik stinged to the phase, the indicator on the rotation starts to light up.

Get respect! When the dot reaches zero, the indicator light is not lit.

Like Bachimo, with the help of such an instrument, it will be easy to know the phase and zero, but more safely.

Spinner with a neon lamp

Another type, the cream of simple indicator twisting is a voltage tester, equipped with a neon lamp.

Voltage tester with neon lamp

Such an attachment functions like this:

• an electric strum, which is on the surface, which is vimiryuetsya, vіddaєtsya on the sting of the vimirnik;
• Sweep the strum through a resistor (between the strum), which is 0.5 mOhm (minimum limit), using a neon lamp mounted on the contact in the housing;
• another contact of the lancet, the necessary inclusion of this type of light, is zamkaetsya people, on the handle of the twist.

Get respect! This type of voltage indicator is characterized by the inclusion of a light bulb in the lamps of the parameters in the capacity and support of the body of a person.

As a result, when such a tool is used, the light is less likely to occur due to the presence of a voltage. At one time, for the presence of contact with the body of a person, the light will not be guarded.
Until the failure of such a voltage indicator, it is possible to reach a high threshold, which is victorious for the voltage indication (type 60V). Models with a neon light bulb have proven themselves well in the situation by looking at the phase of the presence of the voltage. Z її with help it is not possible to determine the urvish of the lancer.

Voltage indicator with light bulb

The most popular and demanded for today type of indicator twist is the model equipped with a light bulb.

Indicator spinning with a light diode

The principle of functioning of this tool will be similar to the fact that the twisting of the indicator type with a neon light bulb is used. The main difference between models lies in the fact that light differences can significantly lower the threshold for indicating the voltage. Here, the light of the light of the poster is to be measured for the obviousness of the voltage, less than 60V.

Battery voltage indicator

The above-described models use windings of the indicator type, which are equipped with a light bulb and work with batteries (autonomous cords).

Indicator twist on the battery

Such varieties are richly functional, which allows them to win in the most challenging situations. Adding rich functionality is allowed by an additional element in the attachment of such tools - a bipolar transistor.
Before transferring the functions of indicator autonomous windings from the building, enter with a light diode:

• znakhodzhennya shaved lanceug;
• phase designation;
• znakhodzhennya mіstsya, where it became a miserable conductor;
• designated location of wiring. Such a function has become available to the obviousness of the voltage in any non-contact method;

Get respect! The construction of a contactless electrical system, according to the wire, is based on the induced magnitude of the magnetic field.

• polarity of different gerel strumu

Krіm tsgogo it is necessary to indicate that similar tools are built for the designation of microfluidic vibrance. Therefore, the stench can be vicorated for robots with micro-furnaces.

Electronic type of pressure indicator

Another type of indicator type of twisting is the electric model. Such a spin can be presented in two forms:

• with a rare crystal screen;
• without new.

Electronic spinning with a rare crystal screen

This type of instrument is equipped with an audible alarm, the activation of which indicates the presence of the voltage. As a matter of fact, this tool is supposed to make excuses and do it with a multimeter that is easy to use.
For the help of a built-in RK display, you can not only determine, but also know the magnitude of the voltage. Sound, this parameter is in the range from 12V to 220V.
The principle of operation of electronic voltage indicators is similar to all other models.

Rules for stopping voltage indicators

When working with similar tools, there are a number of rules that you need to know so that everything works correctly.
Here it is necessary to follow the following recommendations:

• dotrimannya rules for safe work with electrical circuits. Tse means that all manipulations with the indicator twist should be carried out with the package vimikachs turned off;

Vimkneni vimikachi in the electrical panel

• remember that the electric stream should flow through the conductor with the smallest support (from plus to minus);

Get respect! Whether any electric device would be less functional in that case, if it is the phase / plus through the lancet to go to the zero / minus wire of the line.

• for the assessment of folding electrical appliances, a similar indicator meter is not suitable for any type. With help, you can check the correctness of electric lanterns;
• in houses and apartments - standard mesh with a purity of 50Hz and a voltage of 220V;
• when working with such a twist, it is necessary to know that voltage is coming to the phase (+), zero is leading to the transformer (-), and the third wire is grounding (for example, at the rosette).

When coring with a signal twist in different robots, the obov'yazkovo should follow the rules. In another way, you can take the opposite result.

How to change the tool

As if it were an accessory with vimiryuvalnymi akostnosti, our signal twist and turn will require a re-verification of its practicality.

Get respect! p align="justify"> The work of the robot is always under constant pressure for the correctness of the winding tool.

Working indicator twist

So that our signaling tool is always known to the ready to work the tension, to give respect to such nuances:

• the body of the tool is forever guilty of being left clean and clean. On the new fault, there are daily cracks;

Get respect! For obviousness, the corps needs to be replaced. Otherwise, your safety for an hour of work is not guaranteed by a picker.

• Before the cob works, it is necessary to perekonatisya at the practicality of the tool. You can change it simply by bumping the conductor, for which there is a voltage;
• as the batteries are strong, it is necessary to replace them. For this, carefully twist the cap and replace the old batteries with new ones. The smut here is not to confuse the polarity. Otherwise, the spin is not functional.

Do-it-yourself repair of a signal twist, if any breakdowns are detected, it will be irrational - it is cheaper to buy a new tool.

Visnovok

The need for an indicator switch is there, where there is wiring and electrical appliances, etc. have any kind of appropriation. Correctly working with her, that pidtrimka of the practical work will be the guarantee of your safety when working with electricity, and with your own hands, you can fix small breakdowns of both equipment and the wiring itself.
