1. Connect the working circuit according to the electrical schematic diagram. The transformer shell and console must be well grounded.
2, through the power supply, the green indicator light on the console, press the start button, the red indicator light, this time the riser waiting for the flow.
3. Rotate the regulator clockwise and evenly. Pay attention to the output current indication on the console until the required high current. In order to ensure the test accuracy, a standard ammeter can be connected in series with the meter terminal.
4. In the course of testing, if abnormal phenomena are found, the power supply should be cut off immediately and the cause must be ascertained before testing.
5. After the test is completed, the regulator must be returned to zero. Press the stop button to cut off the power and cut off the power supply before removing the test wiring to ensure safety.
6. The large current generator is designed for a short period of time, so it is not allowed to work under rated capacity for a long time. Especially, it is not allowed to exceed the rated current to prevent overheating. 1500 megohmmeters can be used only when measuring the insulation resistance between the coils and the coil to the ground and their resistance value is not lower than 0.5 megohms.
7. In use, the up-flow transformer and console must be grounded reliably to ensure safety.
8. When using, it should be slowly and evenly lifted, and excessive vibration should be avoided during handling.
9. The pressure regulator and brush contact surface should be kept clean. Use 90% alcohol to wipe clean
