Advice 1: How to take readings with the meter mercury 200

Meters "mercury 200" allow electricity to 4 tariffs in 8 time zones of day to 8 day type. Most often such detail is not required. It can work in automatic systems for commercial accounting of electricity. But if you don't have one, need to learn how to take readings manually.

How to take readings with the meter mercury 200
Instruction
1
Remember your fare type. The most common one-part and two-part. First do not change during the day. For the calculations the entire volume of energy consumed is multiplied by the installed cost kW/h. In the second case, is given separately in the daytime and at night. Each period has its own electricity price.
2
Read liquid-crystal display, without pressing any buttons. Before you - the amount of energy consumed during the operation of the counter at this rate. The inner room rate for the counter is expressed by the indication on the screen to the left. Before the number is the letter T: T1, T2, T3, T4. If you have a single, then the more you read nothing.
3
Subtract from take readings data for the previous month. Multiply them by the value of kW/h and you will get the amount of payment for electricity this month.
4
Click "Enter" to see the amount of power used on other types of tariffs. After the third tap, if the counter is configured to the maximum number of tariffs, the screen shows the total amount of electricity consumed. That is, you do not need to write off the testimony in all intermediate positions, just press the desired number again on the bottom button.

5
Click on the top button "O" to know the power loads connected to the meter. The right will be the unit of measurement is
"kW" on the left and the current rate. Press this button again to change the time. To make corrections you need to choose the "Input" button. Each time you press the time increases by 1 minute. It is impossible to make the amendment more than half an hour.
6
Click on the "O" button a third time to specify the date of the deposition. If in this position again, press the "Enter", then you will see the data on energy consumption for the last month. That is, with this meter you do not need to look at previous bills. The device itself will give all the necessary information.

Advice 2 : How to remove readings from a three-phase meter

Three phase electric meters are designed for accounting of electricity consumed in industrial three-phase network at a voltage V. 3Х380 their Main function – control and monitoring of legal consumption.
How to remove readings from a three-phase meter
Instruction
1
Determine the type of the counter. Modern industry produces a variety of models of three-phase meters with which you can measure the power consumption at the same time in several directions, and even multiple rates. Basically there are two types of counters – induction and electronic. Despite the use of more advanced technology in electronic counterx, their share compared to induction is relatively small. This is because they were commonly established until the mid 90-ies and their period of validity has not yet expired.
2
In practice, the indications of the meter may be removed as the representative of the supplier of electricity and owner of the counter. Inspect the counter. If it lists the three-digit indicator of electricity, then this means that a full rotation of the counter mechanism corresponds to 1000 kWh. For the four-digit counter , this figure will be equal to 10000 kW/h. Upon reaching values of, respectively, 999 and 9999 kWh readings will reset and starts a new report. When you take the readings with such meters, be sure to consider their characteristics.
3
In determining the amount of electricity consumed, you should use the difference in readingsx for the previous period and the last readings. In other words, the value of the testimony subtract the value recorded in the previous times, so you will get the value of the consumption for a certain period.
4
To translate the result into money, the difference in kilowatt-hours multiply by the current tariff. A situation may arise when you need to take readings with the meter replacement, for example, with a three-digit to four-digit. In such a situation, calculate the last readings of the old meter, and then sum them, after some time with the readingswe've a new counter.

Advice 3 : How to take readings with a mercury 200

Even in older homes often replace mechanical electricity meters with electronic stamps "mercury 200". While at first the tenants often have difficulty with the removal of indications of counters.
How to take readings with a mercury 200
Instruction
1
Without pressing any buttons on the counter, consider its indicator readingscorresponding to the current tariff (i.e. tariff, which applies in that part of the day in which the reading).
2
Find out what the tariff is valid in the current part of the day, the icon located on the indicator to the left of the statement. It consists of the letter T and the numbers corresponding to the number of tariffs (1 to 4).
3
To learn the readings of the counter corresponding to the other rates, press the lower key until until the the one testimony which you wish to read. To get out they will be cyclically (from first to last, then the total testimony, then the first rate). All rates can be, depending on the type of machine, from 2 to 4. When displaying the total readings for all tariffs icon is displayed in the "Amount".
4
Use the spin "mercury 200", you can simply and quickly find out the total power of all loads connected to it at the moment, without the tedious counting of revolutions or outbreaks. To do this, briefly press the top button - you will see on the display this parameter.
5
The meter can automatically calculate for you the amount of electricity consumed from the first day of the previous month on the first day, freeing you from having to carry out the subtraction. To do this, in the mode display power, press the top button again to display time. After the next pressing will display the date. Finally, the next press will display the energy consumed over a specified period of the first tariff. Subsequent clicks will cause the counter to display energy consumption over the same period for other rates, then the total consumed energy.
6
While in display mode energy consumption for the previous month on a particular tariff, press the lower key and you will see the equivalent figure for the month prior to the previous one. Subsequent clicks, you can view the history of readings for the next eleven months.
Note
Never highlights the counter open fire.

Do not touch the busbars and bare wires inside the shield.

Do not engage in hacking attempts and rollback counter.

Advice 4 : How to take the depositions of three-tariff electricity meter

Multi-tariff electricity meters are installed today in many new homes. And in older homes they may be embedded in the implementation of a major overhaul. The most common of them are electronic counters brand is mercury-200.
How to take the depositions of three-tariff electricity meter
Instruction
1
Before reading the meter , put on dielectric footwear. With him in the porch or hall, take a flashlight, even if the room is well lit. In any case, do not read the testimony in the light matches, candles, lighters. For clicking the spin button you will need to open the flap. Do not touch it to any live parts, even if they seem isolated. Do not touch anything except the buttons.
2
Aim the flashlight on the counter display if the indications on it are badly visible.
3
Check in which mode you have configured the counter: manual or automatic. Switching between these modes manually is impossible, it can be done only by the employees of the dispatch by special communication lines (if any). If the flap is closed on the lock, and the display of the meter switches between segments "T1", "T2", "T3" and "Sum" means automatic mode. When on any of the segments with the letter "T" and the digit indications on the display correspond to the rate number associated with this figure. When the included segment Sum, the readings correspond to the sum of all three rates.
4
If the counter is configured to work in manual mode, the indicator is always on the segment with the letter "T" and number of the tariff, which is valid in the current time of day. To switch segments "T1", "T2", "T3" and "Amount", press the upper key - they switch on the ring, and the display will appear the corresponding information. Only write the corresponding rates indications.
5
In case of three rates, the calculation of the cost consumed per month energy to exercise according to the following formula:C=(t1*e1)+(t2*e2)+(t3/e3), where c is the total cost consumed per month energy (RUB), en is the amount of energy consumed per month at the rate n (kWh), tn - the cost of one kilowatt-hour of electricity at the rate n ( € ).
