What can you do with a digital multimeter?

Digital multimeters combine the testing capabilities of single-task meters: They are capable, for example, of working as a voltmeter, measuring the difference in potential in volts; like an ammeter when it throws measurements in amperes product of the calculation of the intensity of the current and like an ohmmeter in those cases in which it is adjusted so that it measures the ohms of an electrical resistance.

In short, with these devices you can measure resistances, diodes, transistors, capacitance, frequency, continuity in audible form, direct current voltage, alternating current voltage and amperage, values ​​that are used to check the correct functioning of the device components and electronic circuits. Some even incorporate functions to perform temperature measurements, characteristics that make this device an indispensable device for those who are dedicated to electrical repairs or have interest in that area.

What is a multimeter and how does it work?

It is a test tool, almost always pocket, also known as a multimeter, which serves for the appropriate measurement of two or more electrical values ​​mainly voltage, current and resistance. Commercially it is also known by the name of tester.

It is a standard diagnostic device generally for the use of technicians in the electricity or electronics industry, which allows the measurement of current in continuous or alternating following several margins of measurement in each of the cases.

Initially these devices were created in an analogical way and, with the arrival of technology, the manufacturers started to market their digital versions, both have the same functions, however, the latter are the most common nowadays and, according to the Expert opinion and knowledgeable, also tend to be a little more accurate, reliable and are available in variable prices.

Although there are some more sophisticated than others, making comparisons we can see that these teams usually have several parts or components in common. First, there is the screen where you can see the result of the measurement, the buttons to select various functions, the selector or rotation dial to select the primary value of measurement and the input sockets where the terminals of the tips are connected test.

The digital multimeters have a fairly simple operating system that consists of turning the rotation knob of the device to select the parameter to be measured; then the cables or test leads are connected to the input sockets of the device and these are then brought to touch the device whose load magnitude is to be known. On contacting the tester, the data of the measurement result is displayed on the front screen.

The multimeter’s selector is usually one of the most important parts of the device since its rotating system allows to select different elements that can be measured, including different selections for the same parameter.

Usually the function of the rotary switch or selector is complemented by a series of buttons that allow a more specific selection of the characteristics of the values ​​to be measured, even some of the most detailed and sophisticated equipment come with small transistor measurement sockets. .

About the operation of these equipment is essential to know some details that allow its correct use. To measure resistors of a circuit with a digital tester it is necessary to do it without there being current flowing through them, that is to say, that one of the pins of the circuit must be removed to carry out the measurement correctly.

If you want to measure the voltage, it is best to first know what type of current is being measured, that is, we must know if it is a direct current like the batteries usually have; or alternating, equal to what is usually in the wiring of homes and offices.

In the case of continuity measurement, it is necessary to verify the characteristics of the track or circuit to be measured, for example, if they are cut or have a problem. In most cases the measurements of these elements do not cause problems, however, it is necessary to be careful when measuring a diode because they let the current flow in only one direction, so it is essential to place the batteries correctly to do the measurement.

Multimeter or Analog Meter

It is, basically, the predecessor of the digital multimeter, it is a more complex artifact with scales of values ​​that are understandable, in most cases, by those who have knowledge of electricity or electronics.

This type of equipment is also composed of a rotation knob and outputs the results on a scale of values ​​of different load magnitudes, indicating the value measured with the movement of a needle.

Normally, modern analog multimeters are equipped with a mobile coil measurement system. The first generation, however, were equipped with a mobile iron measurement system.

The analog multimeter measures the current by moving the coil counter with the appropriate internal resistances, which are inside the circuit, based on the selection of the range switch. It is used to measure the direct and alternating current, as well as the voltage. It is also used to measure the resistance and there are some that also serve to measure transistors and capacitors. The actual resistance of the analog multimeter depends on the chosen range, as well as the sensitivity.

Despite digital technology, some manufacturers are still betting on this market because these teams are still used for academics in schools, training companies, laboratories, universities and in the research sector. However, in the opinion of some users, this equipment does not stand out in the accuracy that digital devices do.
