Capacitometer

November 1, 2021

In electronics the capacimeter has been used since the 18th century. It is presumed that around the year 1750, when electricity was still not seen as a science but rather as an entertainment. It was designed by Germans but the English later perfected it.

It is a test tool that is used to measure the electrical magnitude that is present in an electrical capacitor or capacitor. With it you can check the capacity it has and know if it is suitable for use.

Many times you cannot recognize what capacity the variable capacitor circuit offers or find a capacitor that needs to be tested. However, in these cases the ideal instrument is the capacitor.

What is a Capacimeter?

The capacimeter is an electronic measuring instrument, which tells you the capacity of certain capacitors. It is a device with which it is possible to measure magnitude with excellent precision, for this reason it has become a very common tool in all laboratories.

With this wonderful tool you will be able to check the delimited data of electrical capacities, as well as the resistance and inductivity values ​​of any capacitor, giving their values ​​in certain cables and circuits.

What is the Capacimeter for?

The capacitor is one of the most effective and widely used instruments today in the field of electronic repairs. Most of them can measure capacitors, from scales that are too low, such as nanofarad and picofarad, the limit will depend on its manufacturer and its quality.

It is used to measure the capacity that is present in a capacitor or capacitor of a ceramic or electrolytic type. It circulates the signal of a certain frequency through a capacitor, to then perform a calculation and thus obtain the value of the capacitor’s capacity measured, in this way it is visualized through a glass display.

The application of this tool goes beyond just measuring the capacitance of the capacitor, you can determine the value of an inductance indirectly.

How does the Capacimeter work?

The Capacimeter is an electronic measuring instrument , which is very simple to use, however, you must know how it works, so that you can give it the correct use and reading of the results of its analyzes.

This instrument has a screen where the results are reflected, to perform the measurement, this instrument has two tips that are placed on the negative and positive pairs of the capacitor. The instrument offers you the option of selecting the measurement scale, which will generate the exact electrical charge that the capacitor has.

In the event that the measurement is given in the wrong way, you will be able to determine if the capacitor works or if, on the contrary, it no longer fulfills its functions. It is possible that when you make the measurements, the capacitors, even when they are new, generate results lower than their capacity, this is because the energy that accumulates in them is lost over time.

Using the Capacimeter

The capacitor is an instrument used in most laboratories , as it is considered a very necessary tool, if not indispensable for the design and development of circuits in which capacities intervene.

With it you can check the status of a certain capacitor and at the same time know the value of its capacity. It is very useful to verify capacitors that have been disassembled from other installations, in order to discard those that are in bad condition and to be able to classify those that work and take advantage of them for future assemblies.

It should be noted that, with variable capacitors, the capacitor will give you an exact prediction of the minimum and maximum values.

Capacimeter types

Today you can find a wide variety of capacitors on the market, you can find the right one according to your preferences and needs.

Sometimes, you may see capacitors whose value that is printed on them has been erased, in these cases it is necessary to have a tool as useful as this at hand. The result will be the same with whichever of the two capacitors you decide to use.

You will be able to find the professional, who in addition to measuring the capacity, can calculate the ERS that the capacitor has. It is the perfect tool when it comes to measuring capacitors, since it can measure those of different frequencies, as is done in any specialized laboratory.

  • Digital capacitor

This is an instrument with the electrical capacity of a capacitor, the difference with the analog is that it has an LCD screen, which indicates the value of the capacity. This model is usually the most popular on the market.

  • Analog capacitor

It also measures the electrical capacity of the capacitor, it has a needle to indicate said measurement by expressing the electrical magnitudes that the capacitor has.

Both are very effective tools in the world of electronic repairs . Electrolytic capacitors tend to fail a lot in electronic equipment, especially in power stages in which the temperature is very high, causing the capacitor to lose the electrolyte that is deposited between its plates, causing erratic operation or circuit failure.

Capacitor characteristics

When I speak of a capacimeter, I am referring to an artifact whose frequency is established by the capacity to be measured. E l oscillator is connected to a frequency counter prepared for measuring periods, it can be seen the capacity of the capacitor being tested. It has certain characteristics:

  • A micro controller
  • In case of being analog, it has a needle indicator
  • Digital display, if digital
  • Test clips to hold the capacitors, usually short to facilitate the measurement of capacitors: a red one, with which positive polarity is measured, and a black one with which negative polarity is measured
  • An indicator wheel that displays the scales in different magnitudes nano farads, milli farads and micro farads

These are the basic characteristics of every capacitor, its shape, manufacturing material and size may vary from one manufacturer to another.

Importance of Capacitor

The capacitor is considered an essential instrument in any laboratory , for the elaboration of circuits in which the capacities intervene, as it is a very useful tool to check the status and the capacity value of any capacitor.

If you are passionate about electronics, you will long for the capacitor to measure the value of capacitors that you get from old electronic devices, such as computer memory cards, old radios, among many other systems, from which you can recover these parts.

In addition to measuring capacity, it can measure other parameters such as: leakage, inductive component and dielectric resistance, bearing in mind that the limit of capacity that can be measured will depend on the manufacturer and the quality of the device. The most common are in maximum ranges of 10,000 or 20,000 mf, being this enough to test the capacitors that are placed in most electronic devices.

If in your laboratory you still do not have a capacitor, do not hesitate to buy it, it will be very useful and useful. You will surely find the best model, the one that best suits you, your tastes and needs.

Born and raised in Brussels in an English family, I have always lived in a multicultural environment. After several work experiences in marketing and communication, I came to Smart Water Magazine, which I describe as the most exciting challenge of my career.
I am a person with great restlessness and curiosity to learn, discover what I do not know, as well as reinvent myself daily, someone who is curious about life and wants to know. I enjoy sharing knowledge.
This is my personal project but I also collaborate in other blogs, it is the case, the most important web on water currently exists in the US, if you are interested you can read my articles here.
