Detailed instructions for beginners

The meter is almost the most important tool for any electrician and will be very useful in every home. Indeed, thanks to him, you can always check the integrity of the network, if there is any voltage and current of a particular device.

If you think that it is difficult to use, then you are deeply mistaken, and in this article I will explain how easy and simple it is to work with tseshka.

What are you Multimeter

First Things First let's find out what you can measure with the help of this device, and the miracle is there any indication on the front of his bar. So, you can see the following notation:

- OFF This position speaks for itself and indicates that the tester is turned off.

- ACV the acronym says us that is measured by the break voltage.

- DCV and here we see a constant voltage.

- DCA then measured by a constant current.

- Ω and in this section is calculated resistance.

For easier perception's visual image of the meter giving explanations

Note the circled area with large jacks, you can watch here for three connectors, and wire the two. This means that to get the true measurement data need to choose the correct slot. But here it is actually very simple. Black wire is always put in the socket marked

COM. But the changeover between the other two terminals is performed using a probe with a red coloration

And in the case of the vast nest suitable for household purposes "VΩmA ". This situation can produce a dial, voltage measurement and to measure the amperage 200 mA inclusive.

But if you need to measure current up to 10 A, it is necessary to reposition the red probe in 10ACD connector.

These provisions are very important, if you do not obey them, tseshka pass away very quickly into disrepair.

It can also have someone else lying around the old tseshka dial with a pointer, and so it has exactly the same functionality as that of the meter with an electronic scoreboard, but the latter is easier to work. So as you can see immediately the exact value of the measured parameter, and the error in the pointer instrument is somewhat higher.

We have examined carefully and tseshka now know what a responsible position, now let's move on to direct measurements.

we measure the voltage

So, let us now with our tseshki to measure voltage, for example, the nearest outlet. So we need to probes were in the positions as shown in the picture.

A switch arrow combine with point 750 located in sector ACV. All probes are now inserted in the socket and look at the scoreboard and seeing the numbers indicate voltage.

If you see an option below 200 VoltIt is possible to change the pointer position 200For accurate measurement results.

If you need to measure postoyanku, it is done as follows: the test leads are left in place, the pointer switch to the desired position us (for example, the car will suit the situation in the 20 Volt) and produced by attaching to negative black wire to positive and red - in this case we will see the value of a plus sign. If, however, will see a minus in front of the numbers, then your red probe sits on a red and black on black.

Important. Voltage measurement is carried out parallel adjoining probes. Most importantly, do not touch the exposed parts of the device when it is connected to the measurement with bare hands, as you can strike shock.

we measure the current

Everything here is a little more complicated, but this option is in the home is almost not needed. I will just tell you to be aware of how it's done.

First Things First, we need you to know how much current you need to measure: a constant or variable. Then we pretend so as its value if it exceeds the rate at 200 mA then insert the red end of the socket 10ADC.

Important. The current is measured by successive addition and since the current circuit break is undesirable, before tseshka measured value to include its chain. For this purpose one wire feed unit measured unscrew and connect tseshka formed gap, the ends must be tightened.

After all the preparations include tseshka and measured load. If everything is correct, then we are seeing, for example, a burning light bulb, and on the dial, the current consumed by it. Disconnect tseshka necessary only after switching off the load.

to measure resistance

This is the simplest and perhaps the most demanded in the home multimeter function. In order to measure the resistance takes the arrows in the section and select Ω we need setting.

Important. Before you measure the resistance, be sure to check that there is no element of tension. Otherwise multimeter resistance measurement function fails.

Thereafter, the ends leans to the measuring element and see what it gives the resistance. If you see an inscription OVER it means setting very low and you want to move the arrow to a higher range.

continuity

This is the simplest and perhaps the most demanded in the home multimeter function. With this function you can determine the integrity of, for example, wires to carry. If tseshka sounds an alarm when connecting test leads to the ends of the wires and the display shows zeros that lead intact.

Special bonus for those who read to the end, and who wants to know what your body produces stress. To do this, put the pointer in the position 200m in the sector DCV, Insert probes so black in COMAnd red in VΩmA. Now grasp the exposed part of the probe and you can see what your body produces stress. And yes, it is perfectly safe.

Now you know how to use such an important and necessary instrument as a multimeter. Thanks for attention.
