Intelligent meters "run fast", is there a problem with smart meters? In fact, this probability is very small, because smart meters from production to installation to the customer's home, need to go through a lot of tests: the meter factory is responsible for the first school, second inspection and spot checks; quality supervision departments in addition to strict requirements for the qualifications of the meter manufacturers, but also mandatory verification of each smart meter, and before entering the home to spot check some smart meters technology; Supervisory departments will carry out "flying inspection", that is to say, without prior notice, direct sampling inspection of smart meters on the assembly line or at the packaging end is qualified. So the probability of a problem meter outflow is comparable to winning the lottery.
