1. Select an electroscope with a suitable voltage level according to the rated voltage required by the electrical equipment and lines.
2. The electroscope should be wiped with a clean, soft, dry cloth before use to prevent flashover and fear of electricity.
3. It is necessary to conduct self-test before use. Press the self-test switch, and the electroscope will send out continuous and intermittent sound and light alarm signals. If there is no sound and light alarm, it means that there is a problem with the electroscope and cannot be used continuously.
4. When the battery voltage of the electroscope is insufficient, the battery undervoltage indicator light will automatically light up, indicating that the battery should be replaced.
5. Before use, the electric test should be carried out on the live equipment of the same level of voltage to ensure that it is normal before use to ensure personal safety.
6. When using, the operation lever must be pulled out completely before the electric inspection operation can be carried out.
7. The electroscope must conduct preventive tests on a regular basis to ensure its safety performance.
8. In case of damage, it cannot be disassembled without authorization.
9. The electroscope should be stored in a place with good ventilation and dry environment.
