Instrument Usage Method
1. Connect the working circuit according to the electrical schematic diagram. The transformer casing, operation console, etc. must be properly grounded.
2. Connect the power supply, the green indicator light on the operation console lights up, press the start button, the red indicator light lights up, at this time the current booster waits for current boosting.
3. Rotate the voltage regulator evenly clockwise, pay attention to the output current indication on the operation console until the required high current is reached. To ensure test accuracy, a standard ammeter can be connected in series at the instrument terminals.
4. During the test, once any abnormal phenomenon is found, immediately cut off the power supply, find out the cause, and then conduct the test again.
5. After the test, the voltage regulator must be returned to zero, press the stop button to cut off the power supply, cut off the working power, and then remove the test wiring to ensure safety.
6. When conducting high current tests, connect the working circuit correctly according to the product circuit diagram. According to the size of the output current, select the position of the large and small range switch. First return the voltage regulator to zero, then press the start test button (green), at this time, hold the handle of the voltage regulator and slowly rotate the handwheel clockwise while watching the ammeter until the required current value is reached. After the test reaches the set value, immediately return the voltage regulator handwheel counterclockwise to zero, press the stop button, and cut off the power supply.
Operating Precautions
1. For newly installed or long-term unused current boosters, before operation, use a 1500 megohmmeter to measure the insulation resistance between coils and between coils and ground. Only when the resistance value is not less than 0.5 megohms can it be used.
2. During use, the current booster transformer and operation console must be reliably grounded to ensure safety.
3. When in use, the current should be increased slowly and evenly, and avoid excessive vibration during handling.
4. The contact surface between the voltage regulator and the brush should be kept clean. If necessary, wipe it clean with cotton yarn dipped in 90% alcohol.
5. This equipment is designed for short-time work, so it is not allowed to work under rated capacity for a long time, especially not allowed to operate exceeding the rated current to prevent overheating.
6. This equipment should be stored in a clean, ventilated, and dry indoor environment.
