1. Selecting Power Supply Mode: Press the 'Mode' button until the display indicates Power Supply mode (e.g., showing voltage and current output).
2. Setting Voltage and Current: Use the 'Voltage Setting' and 'Current Setting' buttons, then rotate the 'Adjustment Knob' to set the desired output voltage and current limits.
3. Output On/Off: Press the 'On/Off' button to enable or disable the output. The button will illuminate when the output is active. A long press can set the automatic output function to activate 5 seconds after booting.
4. Overvoltage Protection (OVP) and Overcurrent Protection (OCP): Press the 'Ω/OVP / ÷/OCP' button to access OVP/OCP settings. Use the adjustment knob to set the maximum voltage and current thresholds. These functions protect your circuit by automatically shutting down the output if the set limits are exceeded.
5. Constant Voltage (CV) and Constant Current (CC) Output: The device automatically switches between CV and CC modes to protect the circuit. If the actual current exceeds the preset current value, the power supply automatically switches to CC mode.
6. Memory Functions: The device supports 4 groups of memory shortcut parameters for quick recall of frequently used settings. Use the 'Memory' button (F1) to save and recall these settings.
7. List Waveform Editing Output: The unit allows for editing up to 10 groups of timing output, enabling complex test sequences.

6.2 Multimeter Mode

1. Selecting Multimeter Mode: Press the 'Mode' button until the display shows multimeter measurement options (e.g., V, A, Ω, F).
2. Connecting Multimeter Leads: Insert the red multimeter lead into the positive (+) multimeter voltage/current socket and the black lead into the negative (-) COM socket.
3. Selecting Measurement Type: Use the 'Ω/OVP / ÷/OCP' button to cycle through different measurement types: Voltage (DCV/ACV), Current (DCA/ACA), Capacitance, Resistance, Diode, and Continuity.
4. Performing Measurements: Connect the multimeter leads to the circuit or component you wish to measure. The reading will be displayed on the LCD.

7. Maintenance

• Cleaning: Use a soft, dry cloth to clean the exterior of the device. Do not use abrasive cleaners or solvents.
• Ventilation: Ensure the rear fan is free from obstructions to allow for proper airflow and cooling.
• Fuse Replacement: If the device fails to power on, check the fuse located on the rear panel. Replace it with a fuse of the same type and rating (e.g., 250V, 15A for 200-240V AC input, or as specified on the unit).
• Storage: When not in use for extended periods, store the power supply in a cool, dry environment, away from direct sunlight and extreme temperatures.

8. Troubleshooting

• No Power:
  • Check if the power cord is securely connected to both the unit and the power outlet.
  • Ensure the rear power switch is in the 'ON' position.
  • Inspect the fuse on the rear panel. If blown, replace it with a fuse of the correct rating.
• No Output Voltage/Current:
  • Verify that the 'On/Off' output button on the front panel is pressed and illuminated.
  • Check OVP/OCP settings. If the output is being limited by these protections, adjust them or disable them temporarily for testing.
  • Ensure the unit is in Power Supply mode, not Multimeter mode.
• Inaccurate Multimeter Readings:
  • Ensure multimeter leads are correctly connected to the appropriate input sockets.
  • Verify that the correct measurement type (Voltage, Current, Resistance, etc.) is selected using the 'Ω/OVP / ÷/OCP' button.
  • Check the condition of the multimeter leads for any damage.
• Unit Overheating:
  • Ensure the intelligent temperature control fan at the rear is not obstructed and is operating.
  • Reduce the load on the power supply if operating at its maximum limits for extended periods.
  • Ensure adequate ventilation around the unit.

10. User Tips

• Gradual Adjustment: When powering sensitive circuits, always start with lower voltage and current settings and gradually increase them to the desired levels to prevent damage.
• Pre-check Connections: Before enabling the output, always double-check all connections to your circuit to ensure they are correct and secure.
• Utilize Memory Presets: For repetitive tasks, save your frequently used voltage and current settings into the memory groups for quick recall, saving time and reducing setup errors.
• Monitor Temperature: While the unit has an intelligent cooling fan, ensure it's not placed in an enclosed space to allow for optimal heat dissipation, especially during high-power operation.
