Before measuring, first check whether the dial hand stops at the "0" position on the left end. If it does not stop at the "0" position, use a small screwdriver to gently turn the middle positioning screw under the dial to make the pointer point to zero, usually called mechanical zero adjustment . Then insert the red and black test leads into the positive (+) and negative (-) test pen jacks, respectively.
Almost all smart meters are used now. It is more precise and intelligent, making it easier for you to control the power consumption. The smart meters are composed of different circuit boards and are the control center of the meter. They are made of larger blank glass fiber boards. A board can make 6-8 circuit boards, depending on the form of the electricity meter. In order to improve the accuracy of the electricity meter, many processes in the manufacturing process are completed by robots.
The electric meter is used to measure the electric energy consumed in a certain period of time, or the electric energy consumed on the load. It is a measurement device. The measurement unit of the electric meter is kWh (that is, 1 degree), so it is also known as the kWh meter, or electric energy. Meters, electricity meters, are widely used in various fields of society.
The increase in voltage also speeds up the meter. The voltage on the line fluctuates within a certain range. If the 220V voltage fluctuates to 237V, it is within the normal range, but the higher the voltage, the faster the meter will move. If a blackhearted person controls the voltage a little, the number of residents' electricity consumption will increase greatly.
