1. According to the required voltage, adjust the "coarse adjustment" knob first, and then gradually adjust the "fine adjustment" knob to achieve the correct coordination. For example, when you need to output 12V voltage, you need to set the "coarse adjustment" knob to 15V, then adjust the "fine adjustment" knob to adjust it to 12V, and the "coarse adjustment" knob should not be set to 10V. Otherwise, the maximum output voltage will not reach 12V.
2. After adjusting to the required voltage, connect the load again.
3. During use, if you need to change the "coarse adjustment" gear, you should disconnect the load first, and then connect the load after the output voltage is adjusted to the required value.
4. During use, when the protection is caused by load short circuit or overload, the load should be disconnected first, and then press the "reset" button, or turn on the power again, the voltage can return to normal operation, and then connect it after troubleshooting load.
5. When connecting power supplies with different rated currents in series, the output current is the rated value of the smallest rated current.
6. Each power supply has a meter head, which indicates the output current or output voltage of the circuit when the A/V status is different. Usually placed in the voltage indication state.
7. Each channel has two output terminals, red and black. The red terminal means "+", the black terminal means "-", and the black terminal with the symbol of "earth" in the middle of the panel means that the terminal is connected to the chassis and is connected to each One output has no electrical connection and is only used as a safety line. People often take it for granted that the "earth" symbol means grounding, and "+" and "-" mean positive and negative power outputs to supply power to the dual power op amp.
8. Two voltages can be used in series. Parallel use is absolutely not allowed. The power supply is a supply meter, so long-term short-circuiting of the output terminal is not allowed.
