In industrial production and daily life, low-voltage testers are widely used in the maintenance and inspection of electrical equipment. However, due to the special nature of electrical equipment, the use of low-voltage testers requires following some key precautions to ensure the safety of operators and the proper operation of the equipment.

Prior to using a low-voltage tester, technicians must undergo professional training and guidance. Understanding the device's functions and operation methods is crucial for effective electrical testing. During the testing process, strict adherence to operational procedures is mandatory; altering device settings or neglecting warnings is prohibited. Regular inspections and maintenance are required for low-voltage testers during use, especially for contact points (components and connection lines), which should be cleaned and checked for damage or contact issues on a regular basis. Any identified problems should be addressed promptly or replaced to ensure the device remains in good working condition. During the testing process, operators must wear standardized protective gear, such as insulating gloves, boots, and goggles. Concentration and strict adherence are essential during operations; it is strictly forbidden for technicians to wear metallic jewelry or damp clothing to avoid accidental electric shocks.

Proper storage and maintenance of low-voltage testers is crucial as well. Equipment should be kept in a dry, well-ventilated area, away from excessive heat and cold. Protect it from direct sunlight and rain. Regular inspections should be conducted during storage to ensure the equipment is free of dust and damage, maintaining its cleanliness and integrity.
