4. Operating Instructions
4.1. Programmable Encoder Adjustment Knobs
The Eventek DC power supply features precision encoder adjustment knobs for setting voltage and current. To adjust a specific digit, press the corresponding knob to toggle through the digits. Once the desired digit is selected, rotate the knob to set its value from 0-9. This allows for accurate and precise adjustments.

4.2. High Precision Power Display
The unit is equipped with a backlit 4-digit LED display, providing highly accurate readings of voltage (up to 0.01V) and current (up to 0.001A). The display also automatically calculates and shows the power value. This ensures clear visibility even in low-light conditions and allows for precise monitoring of output parameters.

4.3. Memory Storage (M1-M3)
The power supply includes three memory storage buttons (M1, M2, M3) to save and recall frequently used voltage and current settings. To save a setting, adjust the voltage and current to the desired values, then long-press and hold one of the M1-M3 buttons until the setting is saved. To recall a saved setting, simply press the corresponding M1-M3 button. This feature streamlines repetitive tasks.

4.4. Output Button and Short Circuit Protection (OCP)
The dedicated Output On/Off button allows you to set voltage and current parameters without immediately applying power to the load, preventing accidental damage. The unit also features Overcurrent Protection (OCP). When OCP is enabled and a short circuit occurs, a buzzer alarm will sound, and the output will automatically stop, protecting both the power supply and the connected device.

4.5. USB Quick Charge Interface
A built-in 5V/3.6A USB port is available for convenient quick charging of mobile phones or other compatible electronic devices. This feature adds versatility to the power supply, allowing it to serve as a charging station for various gadgets.

7. Troubleshooting
This section addresses common issues you might encounter with your Eventek DC Power Supply. If the problem persists, please contact customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| No Power/Display Off | Power cable disconnected; Power switch off; Blown fuse. | Check power cable connection; Ensure power switch on the rear is ON; Inspect and replace fuse if necessary (refer to specifications for fuse type). |
| No Output Voltage/Current | Output button OFF; Overcurrent Protection (OCP) triggered; Incorrect settings. | Press the "Output" button to enable output; Check for short circuits in the load and reset OCP; Verify voltage and current settings are above zero. |
| Buzzer Alarm Sounds | Overcurrent Protection (OCP) triggered due to short circuit or excessive load. | Immediately disconnect the load. Identify and resolve the short circuit or reduce the load. The unit will automatically stop output to protect itself. |
| Inaccurate Readings | Loose connections; External interference; Unit calibration needed. | Ensure all connections are secure. Avoid placing the unit near strong electromagnetic fields. If persistent, contact customer support for calibration assistance. |
