How to read the reading of digital electricity meter and how to read the reading of IC card digital electricity meter
Since human beings entered civilized society, the water, electricity and various materials used by people need to be exchanged with money of. In the past, we used pointer-type water and electricity meters, and pointer-type water and electricity meters are more complicated to read degrees. With the development of electronic technology, people invented the digital meter. It is very simple to read the degree of the digital meter, because the degree of the digital meter is generally displayed directly on the LCD screen. But there are still some people who don’t know how to read it, so below, I will teach you how to read the digital meter.
How do digital meters read degrees
1. Digital meters can be divided into several types, one is a straight-forward single-phase meter, this digital meter It is possible to see the degree directly. There is also a three-phase meter, which can also read the numbers directly. These two water meters will display two kinds of data. The upper data is the current data, and the lower data is the data of the previous month. If you want to know the degree of this month, just subtract the upper degree from the lower degree. .
2. Three-phase digital meters mainly use current transformers, which are digital meters with electrical connection. There are 10 wires in total, and the current ratio is observed by the amount of current in the wiring. Generally, the current ratio will be marked on the current transformer of the digital meter, like this: 100/5, 150/5. The number on the meter needs to be multiplied by the current ratio to calculate the correct amount of electricity. If you want to be accurate, you can add the data of current change loss and line loss yourself.
3. Single-phase metering and three-phase metering are different. Because the single-phase digital meter can directly read the degree on the LCD screen, it belongs to the direct connection. There will be a small red dot on the single-phase meter. The position where the red dot jumps is the total use, and the jump is the remainder. The single-phase digital meter is a dual-graphics meter, which can read the upper and lower degrees.
How to read the IC card digital meter
What is a digital meter? It can be simply understood as an IC card digital meter. Because most digital meters use IC cards to sense and transmit data, and use electrical energy as a data transmission medium. Digital electricity meters are widely used in communities and schools, and have the function of monitoring the flow of water and electricity.
The above is how the digital meter reads the degree, do you know it now? The digital meter mainly refers to the smart meter of the IC card, which can be directly viewed on the LCD screen, which is easier to read. Ic card digital meters are widely used in residential areas and staff dormitories. Magnetic cards are needed to sense them, and the numbers will change. Whether it is a digital meter or an analog water meter, the principle of reading degrees is the same. Now that digital meters have become popular, it is more accurate to calculate utility bills.
