1 The use of electroscopes on electrical equipment for electrical inspection operations shall be carried out in accordance with the relevant provisions of the electrical safety work regulations.
2 Before use, select the appropriate type of electroscope according to the rated voltage of the electrical equipment to be tested.
3 The operator must hold the operating handle and pull the operating lever all the way out to perform the power inspection operation in the order specified.
4 In the case of non-all power failures, the electroscope should be tested on the energized part, then tested at the construction site, and then returned to the electrical part for retesting to ensure safety. This operation cannot be replaced by a self-test button test of the electroscope. The self-test button test is for reference only. The electronic components of the electroscope have a natural aging process. To ensure the safety and reliability of the electroscope operation, and to ensure the personal safety of the grid equipment and the electrotechnical operators, the normal service life of the electroscope is set at three years from the date of delivery, special circumstances. When the service life is to be extended, the manufacturer's consent must be obtained, and the relevant re-inspection procedures must be completed and the consent to extend the use certificate can be used before continuing to use, but the maximum service life must not exceed five years.
