We power test personnel all know that when the large current generator operation, the current is very huge, which requires the majority of users to pay attention to its use method, the correct operation, in order to ensure the safety of production and personnel. So let’s learn about the correct use of large current generator.
1. According to the debugging requirements, connect the current riser and the tested product, and connect the power supply.
2. Select the orientation of the current transfer switch according to the size of the current required by the tested product. Because the current transformer does not allow open circuit, the current transfer switch can only be set to the “large” or “small” orientation, not the middle orientation. High-power equipment can complete high-current gear conversion by adjusting the position of the short-circuit piece in series and parallel.
3. Turn on the power supply, the green light is on (if the green light is not on, the voltage regulator knob should be counterclockwise to zero, until the green light), press the start button, the green light is off, the red light is on, clockwise rotation of the voltage regulator handle, the current to the required value can be.
4. Counterclockwise the voltage regulator handle to zero, press the stop button, the red light off green light, the test is completed.
5. In low temperature and humid environment, start the device for a period of time before using it.
