The electricity meter calculation of the smart meter mainly depends on the three bases of voltage, current and power. In theory, the user can change the current, voltage, meter speed, etc. to achieve the purpose of stealing electricity. The stealing of smart meters must be completed through the internal transformation of the electricity meter, which requires the foundation of an electrician. In addition, smart meters are controlled by computers. Therefore, it is difficult for smart meters to steal power. Below we have summarized some smart meter how to steal electricity.
How to steal electricity from smart meters
First determine what kind of model your electricity meter is (now a great variety of electronic models, electronic watches, electronic LCD performance table, dumb type meter, IC card prepayment meter, digital tube performance of electronic watches, etc.) meter is divided into single phase And three phases, so please clarify whether your meter is single-phase or three-phase, the model of the meter and whether it has long-distance.
1. Connect a wire to the front and back of the front of the meter. The meter should have a resistance. The point will take your line and the meter will not run.
2. The two households can steal electricity by tying together, and the two home appliances will be swapped out of the zero line. The two home appliances will not go.
3. If you are looking for a professional to open the fire table, change the ade7xxx chip circuit inside the analog-to-digital conversion, and then redo the seal, it is probably not visible.
4. Use infrared settings to deploy the device. After cracking the password after connecting with the 485 interface, reset the data, but the programming port is hard-switched.
5. Meters with anti-tampering effects can only be connected directly from the meter to the zero line of the fire directly into the house, throwing off the meter. Otherwise it will be investigated.
7. The ordinary electronic meter with a pour table, liquid crystal electronic watch can use the controller to achieve.
8. Change the internal circuit layout of the meter. Smart meters have a fatal flaw:
1 The user's electricity record is analyzed by sampling the manganese copper shunt. If the internal electronic components are broken down, the amount of the ledger is incorrect.
2 The user's on/off power is connected to the magnetic connection relay installed in the meter to achieve long-distance control. It also means that the user's arrears are relayed by the long-distance signal, if the external magnetic field is disturbed (such as NdFeB permanent magnets. , magnets, etc.) will not open the relay
3 Therefore, in the case of arrears, the electricity cannot be cut off - the user will not pay the electricity fee once it is turned on, and the terminal performance has already owed a power cut, but the user is still using electricity.
9. It is very simple, another way to bypass a smart meter, use this line to the normal power supply to the home, smart watch the normal line, only a light bulb, so a turn on the light, smart watch to run, other The appliance will not take away the electricity meter.
Xiao Bian concludes: The above knowledge about how to steal electricity from smart meters. Xiao Bian reminded that stealing electricity violates the law. Electricity is a commodity, and electricity is used to pay for it.

To create the ideal environment for your fish, proper and regulated light in the aquariums is of premier importance. Fish thrive under proper light but in relative moderation.This means that considerable thought and a modest investment will be required to keep your tank well lit, both for your pleasure as well as the fish.
The light in an average home is generally not enough for the fish living in an aquarium. Living all day and all night in that environment will not be conducive to the fish`s health or even their temperament. Like humans, fish thrive in a warm and pleasant atmosphere. Statistics definitely prove that fish living in a well lit aquarium certainly live longer and appear to be more energetic which must cause us to assume that they are happy.
