1. Before use, select a qualified electroscope with appropriate voltage level based on the rated voltage of the equipment to be tested.
2. The electroscope must be self-tested before use: the method is to press the self-test button with your finger. If the indicator light flashes intermittently and an intermittent alarm sounds at the same time, it means that the instrument is normal.
3. When conducting electrical inspection work above 10KV, the "Electrical Industry Safety Work Procedure" must be carried out. Workers must wear insulating gloves and boots, and ensure a safe distance from live equipment.
4. When testing electricity, the staff should hold the handle part below the protective ring of the electrical appliance, and according to the provisions of the "Safety Working Procedures for the Electrical Industry", first conduct the inspection on the electrical facilities to verify that the electroscope is indeed in good condition before use. , Do not use this instrument in rainy or foggy days.
In order to ensure the safety of people and equipment, according to the "Electrical Industry Safety Work Regulations", the electroscope should conduct insulation withstand voltage tests and start-up tests regularly for three months in humid places and half a year in dry places. If there is any abnormality, it should be stopped. .
