How to read the meter to calculate the degree

If you use a smart meter, it is suggested that you can check the current meter reading through the LCD screen on the meter; A string of numbers on the screen will directly display the integer and decimal readings of the meter. The data displayed on the LCD screen may be different for different models of electric meters. You can press the wheel display button next to the screen to switch the display interface, and check whether the data displayed on the LCD screen is "current total power" or "current positive total active power", that is, the accumulated power consumption of the current electricity meter.

If you use a mechanical electric meter, you can know the accumulated electricity consumption recorded by the electric meter through the numbers in a row of windows on the dial of the electric meter; In general, the red window represents the decimal part, that is, 1 digit after the decimal point; The black window represents the integer part, starting from the far right, with the first bit as one, and so on.

If it is necessary to calculate the actual electricity consumption in a certain electricity consumption period, the electricity consumption = current meter reading number-last meter reading number. If your meter is equipped with a transformer, you need to multiply it by the ratio of the transformer. (The above calculation method is for reference only, subject to the actual payment details of electricity charges. )
