[0002] A tester is an instrument that detects whether an object is charged and roughly estimates the amount of charge. It is divided into low-voltage testers and high-voltage testers.

[0003] Low voltage tester is used to test low voltage electrical equipment with a voltage to ground of 1000V or less. It is also a common electrical safety tool in the home. It is mainly composed of working contacts, voltage drop resistors, neon bulbs, and spring components. This kind of tester works by using the current passing through the tester, the human body, and the earth to form a loop, and the leakage current makes the neon bulb glow.

[0004] High-voltage tester, high-voltage tester is mainly used to test high-voltage electrical equipment with a voltage of more than 1000V to the ground. There are three types of widely used types: luminous type, sound and light type, and windmill type. High-voltage tester is generally composed of three parts: detection part, insulation part, and handshake part.
