For the commonly used electrical appliance testing instruments and meters, it is necessary to carry out regular optimization processing during technical testing, because no matter what testing technology is, it is impossible to guarantee 100% problems. Especially with the rapid development of electric power technology, more diversified methods should be used to optimize the detection methods to effectively solve the corresponding problems and prevent repeated problems from recurring.
With the development of the times and the progress of society, various electrical appliances have become an indispensable part of people’s work and life, and the practical applications of commonly used electrical testing instruments have become more and more extensive. In short, the safety of electrical applications is very important, and testing instruments are indispensable.
