Background

Static electricity is a static or non-flowing charge (a flowing charge creates a current). Static electricity is formed when charges are accumulated on an object or a surface, and the charges are classified into two kinds of positive charges and negative charges, that is, the static electricity phenomenon is also classified into two kinds, i.e., positive static electricity and negative static electricity. When positive charges are accumulated on a certain object, positive static electricity is formed, and when negative charges are accumulated on a certain object, negative static electricity is formed, but no matter the positive static electricity or the negative static electricity is, when an object with static electricity is contacted with a zero potential object (a grounding object) or an object with a potential difference, charge transfer can occur, namely, a spark discharge phenomenon is seen daily.

Some electrostatic potential testers exist on the market, and an ion balance plate is arranged on the electrostatic potential tester, and the ion balance plate can be removed only by pressing buttons on two sides at the same time, but the ion balance plate cannot be easily removed by operators with small strength in use.
