1. Before using the high-voltage test pen to test the electricity, be sure to read the instruction manual carefully to check whether the test is over-period, whether the appearance is damaged or damaged.
2. For the GSY series high-voltage acousto-optic electroscope, the indicator should be self-checked before operation, so that the indicator can be rotated and fixed on the operating rod, and the operating rod can be stretched to the specified length. After self-testing again to proceed. Note that high-voltage electroscopes cannot detect DC voltages.
3. When using a high-voltage electroscope for electrical inspection, first of all, the operation monitoring system must be carefully implemented, with one person operating and one person monitoring.
4. The operator is in front and the guardian is behind. When using the electroscope, it must be noted that its rated voltage should be compatible with the voltage level of the electrical equipment under test, otherwise it may endanger the personal safety of the operator or cause misjudgment.
5. During the electricity inspection, the operator must wear insulating gloves and insulating boots to prevent the damage to the human body caused by the step voltage or contact voltage. The operator should hold the handshake part below the guard ring and check it on the powered equipment first.
6. The high-voltage electroscope is mainly used to test the high-voltage test equipment whose ground voltage is above 250V. Three types are widely used: luminous type, sound and light type, and windmill type.
7. They are generally composed of three parts: detection part (indicator part or windmill), insulation part and handshake part. The insulating part refers to the part from the metal connecting screw at the lower part of the indicator to the end of the cover guard ring, and the handle part refers to the part below the cover guard ring. Among them, the insulation part and the handshake part have different lengths according to different voltage levels.
