It is high voltage test equipment. Before use, observe whether the meter is in good condition. If the following conditions occur, stop using it, and perform corresponding inspections and repairs to avoid electric shock and unsafe accidents. A: The appearance is obviously damaged (such as cracks or damage in the shell, broken skin on the test lead); B: It was severely squeezed during transportation; C: It has been idle for a long time under improper conditions (such as in the bathroom or a relatively humid place). _x000D_ _x000D_ _x000D_ 2. Never open the case during the measurement process to avoid electric shock and unsafe accidents. _x000D_ _x000D_ _x000D_ 3. During the measurement, there is a large voltage input from the test lead. Do not touch the bare wire or the metal part of the test lead directly with hands to avoid electric shock. _x000D_ _x000D_ _x000D_ 4. Although sometimes all the phase indicators are not lit, but there is still a voltage loop, pay attention to prevent electric shock. _x000D_ _x000D_ _x000D_ 5. The circuit voltage should not be higher than 600V during measurement to avoid unsafe accidents. _x000D_ _x000D_ _x000D_ 6. When measuring 200V ACV, the continuous use time should be no more than 60 minutes; when measuring 600V ACV, the continuous use time should be no more than 4 minutes. _x000D_ _x000D_ _x000D_ 7. It is not allowed to use for measurement in rainy outdoor and humid environment, so as to avoid unsafe accidents. _x000D_ _x000D_ _x000D_ 8. Do not let the meter contact with water or other corrosive liquids, and do not place it in an environment with direct sunlight or high temperature and relatively humid temperature, so as not to affect its test performance. _x000D_ _x000D_ _x000D_ 9. Non professionals are forbidden to open the casing of the meter, so as not to affect its test performance. _x000D_ _x000D_ _x000D_ 10. The operator who uses the meter should have received special training, understand the related knowledge of high voltage operation and measurement, and carry out the measurement operation in strict accordance with this manual _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ About feedback If you are satisfied with our products, Pls give us 5 Stars.
