Modern electrical devices are calculated on the fixation of electricity spent in different ways. Now in homes are statistical products that work on electronic components and microprocessors. In many homes that were built earlier, induction devices are installed. These are old models of meters operating on electromechanical schemes. These two species work equally, but consider electricity in different ways. Accordingly, the principle of removal of data from the instruments is different. Consumers should understand the intricacies of how to replace the electricity meter readings from induction or statistical instruments. Devices are constantly in operation mode, counting power and reflecting information on a special display panel or counting mechanism.
Features of the induction meter
This type of electrical appliances operate in residential buildings, educational institutions and industrial enterprises for many years. Devices ensure the accuracy of calculations in class 2.0 and 2.5, reflect information about the electricity used on the scoreboard.
An account mechanism is rotating wheels on which figures are applied. They denote a certain discharge.
The features of the induction meter include:
- Values are reset at the counter in the original condition. They are expressed in the numerical version 0000.0.
- The end number will be viewed 9999.9. This means that one cycle of electricity reference is completed.
- After 9999.9, the number of numbers is shown at 0000.0. The counter of the meter continues.
- The comma shares the whole values of discharges from decimal values. The latest testimony is neglected without recording in the testimony. If they are recorded in values, then the calculations of electricity will have an incorrect result.
How to remove and calculate readings from an induction meter
Data from the device is removed once a month in the same number to carry out the calculation of the electricity spent. The process of writing testimony from the meter looks like this:
- Write on a sheet of testimony for the previous month. For example, for March, when the testimony was recorded at 8876.4 kilowatt-hour.
- Record readings for April - 8989.5 kilowatt-hour.
Calculation of the consumption is carried out by a simple arithmetic calculation of one number from the other. From the testimony for April, testimony is taken for March: 8989.5 (for April) - 8876,4 = 113.1 kilowatt-hour. Thus, for April, 113.1 kilowatt electrical energy was spent.

There are important features when calculating the testimony, when the counter shows this value - 0086.5 kilowatt-hour. The presence on the scoreboard of such values suggests that the counter completely passed the next cycle of work. The calculation of the testimony will be as follows: (1) 0086.5 (for April) -9965.1 (for March) = 121.4 kilowatt-hour. Figure 1 Ahead of the value 0086.5 means switching to a new electricity reference cycle.
In May 1, there is no need to add, since the calculation takes place in a four-digit format.
Electronic electricity meters: features
Mechanical scoreboard in electronic devices, i.e. statistical type, replaced by electronic. The consumer when checking electricity to the table sees not only kilowatts spent for a certain period of time, but also other numbers:- Date.
- Device operation time.
- Other information associated with electricity.
Data update occurs once a few seconds. In multi-zone counters, the testimony is reflected for each zone, which is expressed by the letter T and the corresponding sequence numbers.
Remove the readings in two ways:
- Wait to update the numbers on the board, write off the data.
- Press the "Enter" button. Waiting until the figures are for T1..t4 (for multi-zone counters) or the word "Total", you can record the testimony. Sometimes you have to find a button several times.
Only the numbers of the whole part are rewritten, without taking into account the signs going after the comma.
"Mercury 200"
Counter "Mercury", which is a few species - one idarithric and multitarithic.
Indications from a particular model are removed according to one principle. It differs only the number of times pressing the "Enter" button, waiting for the desired numbers to appear. At first, the instrument shows the time, then the date, and only then - the tariffs for each zone. In the left corner of the screen, the title name is displayed. If there are several of them, first will first appear, then the second, third and so on. Values are recorded whole, without comma.
At the very end, the total (control) amount of tariffs appear. You need to have time to record numbers before their update every 5-10 minutes. If the consumer did not have time to write the necessary information, then the tariffs will have to switch again. The "Enter" button must be pressed and released, waiting for the appearance of the desired value.

The calculation of the expendable electricity for each month is carried out for each zone, and then the readings are summed up.
Energomer
The devices of this company operate on the "Day-Night" system, are two tied and multitiff. Viewing readings occurs by analogy with the meter "Mercury 200". The button on the device has the name "PrSSM", i.e. View. Depending on the modification of the buttons on the counter can be two or three.
By clicking on the button of each tariff, you can get the desired digits of kilowatt-hours. Data calculation is carried out for each zone.
"Micron"
Another multitariff counter, on which one button is located on the housing. It is designed to remove the testimony from each zone. Difference of the meter is that the letters T1, T2, T3, T4 and R + should appear ticks. This means that the indications can be removed and further calculated electricity.
Saiman.
Difference of this model of instruments for counting the expendable electricity is the absence of buttons. To see the readings, the consumer must flip data all the time until the desired values appear. They are marked with the word Total. SAIMAN counter information is reflected in this order - date, time, number number, gear ratio, total electricity spent. For a one-tariff counter, it will be only one word Total, and for multitarithic first indications for each zone - T1, T2, and then only Total. In the testimony in the receipt, it is written for a single-forwarded general reading, and for multitarithic all values - T1, T4, and then Total.
Automatic transmission of data on electricity
Such devices are very convenient to use, since the participation of consumers in the transfer of data is minimal. It is only required to press the automatic data transfer device button once a month, or make data on the company's website. The readings are sometimes sent in different ways: once or several, every five to ten minutes. Such actions are performed in order for the controlling company to receive information and conveyed confirmation to the consumer.You can configure automatic data transmission so that the device reset the testing company once a day. Due to the fact that the data on the counters with automatic data transmission is archived once an hour, consumers are not required every month to record indications, calculate. These functions perform the controller, based on information coming regularly - once a day.

Counters for three phases
Three-phase devices for fixing the expended electricity are divided into two groups - the old type, which work from transformers, and electronic connected directly. It is easiest to take readings from an electronic counter. To do this, it is enough to click on the button and wait for the desired readings to the scoreboard.
Show readings from three-phase meters of an old sample that work on transformers is not difficult, but it is worth showing attentiveness. The readings are recorded from each phase to which the transformer is connected. The obtained data is multiplied by the transformation ratio. The result received and entered into the receipt, as the actual consumption. The transformation ratio is established by GOST or by a controlling company, which, when signing a contract with the consumer, should indicate this indicator in the document, as well as bring the calculation formula.
The process of removing indications from the electricity meters of induction and electric type is different. The calculation is carried out at the same scheme - the new value is taken by the testimony for the previous month. For three-phase meters, the transformation coefficient is also taken into account.
