Smart meters are intelligent terminals in smart grids. They are no longer meters in the traditional sense of the word. In addition to the metering functions of traditional energy meters, smart meters are also used to meet the needs of smart grids and new energy sources.
The three phase digital voltage bidirectional electric meter can be selected through software programming to meet the needs of different users. Can choose photoelectric communication or infrared communication, can expand the cover recording function.
An electronic energy meter is the measuring device of the energy that consumed in kWh. One kilowatt-hour is the amount of electric energy which required to provide an amount of 1,000 watts of power fin a period of one hour.
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.
