The principles of electricity -saving appliances; the single -phase pure metering table generally contains only one basic metering unit, an electronic meter, a light -emitting diode and pulse output port.5) Using high -voltage metal polypropylene capacitors, generally 0.22 ～ 0.47 μF, and the resistance should be ≥AC 250V. When the measuring pulse driver meter, the step motor of the calculation device will instantly absorb a larger current, which is used by the electricity.The principle of the role of the table knows that the electronic meter uses the reverse sensing electricity inspired by the circuit in the electrical electrical appliance, which affects the meter chip, which affects the pulse result.
Power meter savings of electrical appliances
ADH is 398 yuan.But it doesnt make much sense now.It is recommended not to buy.Electricity does not rely on using this machine but trying not to use power consumption.For example, less air conditioning can save a lot of electricity at one time
How to use electricity meters
1. When using the meter controller, please press the key start instrument when using the key 2. Then the meter controller is facing the meter. Press the data scanning analysis button to scan the meter data and analyze.The screen will have a prompt to perform the next step.3. Next, choose the function menu key to select the functions you need (there is stopping billing, slowing down the billing, speeding up the three functions) to complete, and press the function option key to determine which function it is.4. When the prompt operation is completed, the instrument can be taken away.The controller control effect of the meter controller is generally about 10-15 days. It is recommended to re-operate once every 12 days to maintain the effect.
Is it useful for the electric meter?
Home -saving appliances are basically useless. The reason is: First, many people have been on the street some so -called power -saving tricks. Selling a dozen dollars on the street claims that small capacitors that can stop or inverted the meter or have a meter on the spot.Come to demonstrate.In fact, the circuits or meters they demonstrated have been done, so that the electricity used by the experimental bulb is not passed through the meter.Second, many household power -saving manufacturers and dealers exaggerate the efficiency of power -saving efficiency. This household power -saving power saving rate is not very high, usually within 10%.At present, the household electrical meter does not measure the powerless power, and the installation of electrical saving is not a power -free current, but it has no great effect on the reading of the meritable electricity meter, saving power without money.In addition, the civil transformer switch cabinet generally uniformly installs a non -contribution compensation device. This part is saved by the cost profit of the substation department.
