A: 1. Find the meter
If the user is using a mechanical meter, then the meter should be found first, the mechanical meter display generally has a set of data, this set of data is the current total electricity consumption of the meter.
2, distinguish the degree color
When we look at the meter, we should look at this set of data in order from left to right, and the data are generally divided into black and red, where the black area represents tens of thousands, thousands, hundreds, and units from left to right, while the red area represents decimal places.
3, the specific reading
If the value of the black area is 14564, and the value of the red area is 3, it represents the meter number,14564.3 degrees.
4, different meter reading methods
If the user is using a smart meter, then see the degree method is relatively simple, we can find a button on the meter shell, and then press it constantly, every press, the meter display will switch to a different page, when the display displays \"current total electricity\" and other text and value, The value followed by the current total electricity is the total electricity currently used. This set of values will generally clearly display the specific integer and decimal, if the value is 10238.5, it means that the current degree is 10238.5 degrees.
However, due to the variety of meter models, the text and value displayed on the display may also be different. Under normal circumstances, this set of values will be updated every five seconds, the measurement is very accurate, so we should do a good job of monthly electricity degree record
1, the direct single-phase meter and three-phase meter can directly read the number, minus the last reading is the electricity at this stage, and then multiplied by the electricity price can get the electricity at this stage. 2, if it is a single-phase LCD smart meter, the total power and remaining power are directly displayed above, and the direct reading can be done. 3, through the three-phase electric meter connected to the current transformer, first check the current ratio on the nameplate of the current transformer, and then multiply the number read on the meter by the current ratio to generate electricity.

How to calculate the electricity meter
< br >
Electricity meter is short for electricity meter, is used to measure the instrument of electric energy, also known as electricity meter, fire meter, energy meter, kilowatt-hour meter, refers to the measurement of various electrical meters. According to the use, it can be divided into industrial and civil tables, electronic standard tables, maximum demand tables, and multiple rate tables. According to the structure and working principle, it is mainly divided into induction type, static type and electromechanical integrated.

The main types of smart meters are IC card meters, the user holds the IC card to the power supply department to pay for electricity, the power supply department uses the power sale management machine to buy electricity into the IC card, the user holds the IC card in the induction area to brush the contactless IC card, you can turn on the power supply, and the card will be taken away after the power supply. When the remaining power in the meter is equal to the alarm power, the switch off alarm.

If it is an IC card meter, only the light tube display is a single graphics card table. There will be a little red dot on the meter, and the red dot that jumps to the total use is the total use, and the surplus is the surplus. Dual graphics watch, read above or below can be. Three-phase pre-payment meter direct entry type direct reading, mutual inductance type with the meter reading multiplied by the transformer multiplier.
After charging the electricity bill, you can go to the electricity meter to see the meter.
For example, I charge 500 yuan for electricity in Alipay or wechat on my phone, and then go to the meter to see the amount you charge.
For example, charge your phone 500 yuan for electricity, and the meter will show you the sum of what you paid and the original amount.
There are numbers that tell you how much electricity you use, and how much power you have left.
Plug the meter card into the meter and the reading will be displayed immediately.
