1. The instrument must have a good grounding (very important);
2. Connect the power supply to connect the output end of the control console to the input end of the generator, and connect the instrument to the instrument. Turn on the air switch, and at this time, the current regulator waits for the current to rise;
3. Rotate the voltage regulator clockwise evenly, paying attention to the output current indication on the control panel until the desired high current is reached;
4. During the test, if any abnormal phenomena are found, the air switch power supply should be immediately cut off, and the cause should be identified before conducting the test;
5. After the test is completed, the voltage regulator must be reset to zero, the power supply must be cut off by pressing the air switch, the working power supply must be cut off, and the test wiring must be removed to ensure safety;
6. For newly installed and unused current transformers, use a 1500 megohmmeter to measure the insulation resistance between coils and between coils and ground before operation. Only when the resistance value is not less than 0.5 megohm can they be used;
7. Reliable grounding is required for the use of medium current transformers and operating consoles to ensure safety;
8. When using, the flow should be slowly and evenly raised, and excessive vibration should be avoided during transportation;
9. The contact surface between the voltage regulator and the electric brush should be kept clean, and 90% alcohol dipped in cotton yarn should be wiped clean depending on the situation; 10. This device is designed for short-term operation, so it is not allowed to work at the rated capacity for a long time, especially not to exceed the rated current to prevent overheating;
11. This equipment should be stored indoors in a clean, ventilated, and dry environment.
