Insulation resistance meters are widely used in power stations and electrical equipment to detect insulation resistance, which is of great significance to ensure product quality and the safety of people and equipment during operation. The insulation performance of electrical products is one of the important signs to evaluate the insulation quality. One, it is reflected by the insulation resistance.
Before measuring resistance, the circuit under test must be completely discharged and completely isolated from the power circuit. If the test pen or power adapter is damaged and needs to be replaced, the test pen and power adapter of the same model and electrical specifications must be replaced.
