How to look at the degree of a household single phase meter

The last digit of the reading of a single-phase meter is generally a decimal place, (there is a decimal point, or a red number box, or a dotted box and other marks, so you should pay attention to the degree when looking at it.)

In addition, the single-phase meter equipped with a current transformer should be multiplied by the multiple ratio of the transformer when reading, which is the actual electricity consumption. Very few do not check the table for a long time. The meter will start counting from 00000, and the new degree at this time must be added to the original reading from the beginning to the maximum value to be accurate.

Watt-hour meters; It is divided into two wiring methods;

1. a shun-in type; 1 into the fire, 2 out of the fire, 3 in zero, 4 out of zero.

2. a jump-in type; 1 into the fire, 2 into zero, 3 out of the fire, 4 out of zero.

There is no red at the end of the household one-way meter, that is, there is no decimal meter, and the meter is marked with a corresponding number, ten, hundred, thousand, and ten thousand, as shown in the figure below

That's right, the one written above the 1 is the single digit. Ten, hundred, thousand, and ten thousand in order. Some new meters are as small as a single digit for convenience.

Isn't it hot these days, and you can turn on the air conditioner. Don't be afraid, the one with the wheel or the flashing light, 10 times is the only one degree.

Now that we are a conservation-oriented society, saving electricity is also what we should do.

Hello dear, <>

1. Meter code: The number in a row of windows on the dial of the meter shows the cumulative electricity consumption of the meter. The actual electricity consumption in a certain period is equal to the difference between the amount of electricity indicated by the meter at the end of the period and the amount indicated by the meter at the beginning of the period.

The general electric energy meter has a 5-6 digit window, which is painted with black and red markers, the black window represents the integer part, and the red window represents the decimal part, and the degree of the meter is the degree. 2. Calibration current: 10A outside the bracket corresponds to the basic current, the smaller the basic current, the smaller the current of the meter to start the metering, and the higher the sensitivity of the electric energy meter; The 40A in parentheses is the maximum current value, which is the maximum current value that the electric energy meter can pass under the requirements of accurate measurement.

3. Rated frequency: The rated frequency of AC circuit is pulse charge constant: 1600imp kWh means that the electric energy consumed by the indicator light flashing 1600 times is 1kWh active power, which is commonly referred to as 1 degree.

The power of a single-phase electronic meter is generally displayed on an electronic screen, and its display method may vary depending on the manufacturer and model. Here are some general terms and how to read the power of an electronic meter:

1.Active power (kW): indicates the power consumption of the current nuclear lead. Displayed as a number with a decimal point, for example: kw.

2.Electrical Energy (kWh): Indicates the total amount of electricity recorded by the meter. Displayed as an integer, for example: 1234 kWh.

3.Voltage (V): indicates the current supply voltage. Displayed as a number with units, for example: 220 V.

4.Current (a): Indicates the current current consumption. Displayed as a number with units, for example: a.

To check the power of your eMeter, you can follow these steps:

1.Confirm the status displayed by the meter first and whether it is operating normally;

2.Then, press the "Switch" button or "Display" button on the meter, so that you can see the different degrees, and by pressing these buttons to switch multiple times, you can take turns to check the data such as power, current, voltage, etc.

3.If you need to check the energy (kWh), you need to record the time you need (e.g. the current month or the current day), and then after a certain period of time, read the power again and subtract it (current degree - initial degree) to get the amount of electricity used.

It is important to note that the above steps are for reference only as electronic meters from different manufacturers may have different models and designs. If you are unsure how to change the reading of the meter of your appliance, please check the manual of your meter or consult a professional electrical technician for help and guidance.

Do the math how much it will cost you to renovate your home

I believe that everyone will be familiar with it, every family is indispensable to it, the meter can calculate how much electricity is used this month, so it is also very important to learn to read the meter degree. Let's introduce to you how to look at the degree of single-phase meter.

How to look at the degree of a single-phase meter.

The meter degree is in order from left to right, respectively, one, ten, hundred, thousand and thousand, generally speaking, there will be these numbers above the meter degree, if the rightmost is 1, then it means that its reading has no decimal point, if it is, it means that there is a decimal point.

Things to look for when choosing an energy meter.

1. There are several types of electricity meters, including single-phase and three-phase. Generally speaking, civil people will choose single-phase meters, which can be connected to 220V electrical equipment, so such as three-phase three-wire is suitable for power, three-phase four-wire is suitable for lighting or some power lines, and the selection must be based on the power supply and its load to choose.

2. When choosing an electric meter, you must pay attention to its current and voltage, and the current of the meter should be greater than or equal to the current of the line, which will not affect its readiness, and the fierce pin may affect its service life. The load of the meter should not be less than 5% of the rated value when in use, because the amount of energy it consumes cannot be calculated.

3. When you find that the current of the meter can not meet the line current, you can change the large current to less than 5 amps of this small current, and then connect it with the 5 amp meter to connect the fiber, and then multiply the 5 ampere degree of power consumption with the current transformer when calculating the power consumption, so that you can calculate the degree consumed.

Summary: How to see the degree of the single-phase meter related content is introduced here, the method of the meter degree is not difficult, according to the order from left to right, respectively, one, ten, hundred, thousand and thousand, and at the same time for its number to understand it, if you want to know more about the relevant knowledge, you can **** Qijia Home to consult.

1. How to look at the degree of single-phase electronic electric energy meter.

Single-phase electronic energy meters use the method of direct reading to read the reading, and only need to use the number read to subtract the last reading, which is the amount of electricity used during this period.

2. Maintenance and maintenance requirements for meter boxes.

1. Check whether the surface of the meter box is damaged and whether the box lock is intact and whether there is any messy connection according to the requirements; All electrical switches on the meter box should be light and reliable, without obvious noise, and there should be no relaxation and disconnection between the corresponding connecting wire knot and the binding post.

2. When the fuse is to be replaced, the current that is burned off should be matched with the current of the wide field road.

3. There are voltages of various properties on the control box, and the circuit must be clearly distinguished during warranty and maintenance to avoid short circuit events.

4. When cutting off the power supply, it is necessary to immediately detect whether the frame of the control cabinet has reliable grounding, and make the grounding resistance less than 4.

5. Use a brush or hair dryer to clean the dust of the screen board plug-in and each electromagnetic switch part, and check the status and connection of the electrical switch contacts in the control box, whether the insulation of the coil appearance and the action of the mechanical parts are reliable.

6. Clean the dust inside and outside the meter box on time to ensure that the box is clean and safe to use, and the meter reading is clear.

7. Check that the meter, switch, and wire are not damaged and heated, check whether the wire connector base will be loose and oxidized, and check whether the meter label is complete and whether it will be damaged.

8. Maintenance must be carried out by a professional electrician, before the overhaul must be cut off and the power must be checked, the maintenance cycle is best 1 time a year, and the inspection should be carefully filled in the "meter box maintenance record".

The following are the ways to see the degree of various meters: 1. The straight-forward single-phase meter can directly take the number and subtract the reading to be the amount of electricity. The straight-forward meter inlet wire is thicker, and the three-phase meter that is not connected by the transformer 2 and is connected by the current transformer connection has 10 wires.

Pay attention to the current ratio of the connected current transformer. The current transformer has a number on the nameplate. They are all marked with a numerical scale of 5, such as 100 5150 5, etc., which are read on the meter.

This number multiplied by the current ratio is the measured amount of electricity, and to be precise, the variable losses and line losses must be added. 3. The power reading method of single-phase electricity metering three-phase electricity is to read the meter number and multiply it by 3 by directly connecting to the meter. If the meter connected through the transformer wants to read the meter number multiplied by the transformer current multiplier and then multiplied by the smart meter, there is only one LCD screen, if it is a single phase, the total power and remaining power will be displayed directly, and it can be read directly.

If it is an IC card meter, only the light-emitting tube display is a single graphics card meter, then there will be a small red dot on the meter, and the red dot jumps to the total use is the total use, and jumps to the remaining there is the surplus. When using a dual graphics card, you can read above or below. Three-phase prepaid meters have direct readings, and the readings of the mutual inductance meter are multiplied by the transformer magnification.
