February**Dynamic Incentive Plan 1Single-phase energy meter
If the editing meter cannot read the data normally, the solution is: It is possible that the meter is not powered on or malfunctioning, and the meter should be powered on or replaced. It is possible that the meter is wired incorrectly, and it should be rewired correctly. When the positive active power of the meter is zero, and the reverse active power is not zero, it means that the incoming and outgoing lines of the meter may be reversed. Go to the site to check whether the table number of the smart meter is consistent with the table number of the master system, and if not, you need to perform the meter replacement process in the system. Check if the meter is using electricity under the same transformer, as only meters that use electricity under the same transformer can be found. Check the manufacturer of the electric energy meter module, open the cover of the electric energy meter module, and check the solution manufacturer on the internal module. Check whether the module in the energy meter matches the concentrator module, if it is inconsistent, the matching module should be replaced; If it is not yet online, it is necessary to use the handheld test module of the corresponding module manufacturer. If the module is good, it means that there is a problem with the energy meter, and the energy meter will be replaced; If the module lights up red or the module light flashes, the corresponding module should be replaced, and after the module is replaced, the energy meter parameters should be re-ordered at the master station. If the number of energy meters exceeds 600, the meter reading effect is not good, so you can add a concentrator in one station area to share the meter reading task of another concentrator. If there is a black screen and abnormal screen display of the electric energy meter, the electric energy meter should be removed and replaced with a new one. The meter reading distance is long, the carrier signal attenuation is serious, and the meter reading is unstable. The solution to this problem is to install a concentrator in the place where the remote carrier signal in the station area is weak to copy this part of the sub-table; A signal amplifier is installed according to the strength of the carrier signal in the station area. If there is a large interference source near the station area, a concentrator should be added to move the interference source out of the station area. 
Edit and view the voltage indication UA, UB, UC on the three-phase meter screen, and there can be no missing or flashing items. The UA, UB, UC of the three-phase meter must be displayed properly. Tighten the terminals and metal voltage connectors so that UA, UB, and UC are displayed normally in the lower row of the screen to prevent the meter from losing voltage.
