Proper maintenance ensures the longevity and reliable operation of your power supply.

• Cleaning: Regularly clean the exterior of the unit with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Ventilation: Keep the cooling fan and vents free from dust and obstructions. The fan operates automatically to maintain optimal temperature.
• Storage: When not in use for extended periods, store the power supply in a cool, dry place, away from direct sunlight and extreme temperatures.

6. Troubleshooting

This section addresses common issues you might encounter with the HM605T power supply.

• No Power:
  • Check if the power cord is securely connected to both the unit and the AC outlet.
  • Ensure the main power switch on the rear panel is in the 'ON' position.
  • Verify the fuse in the AC input socket. Replace if blown (refer to specifications for correct fuse type).
• No Output:
  • Press the Output button to ensure the output is enabled.
  • Check for active protection (OVP, OCP, OPP). If any protection is triggered, the output will be disabled. Address the cause of the protection event (e.g., reduce voltage/current settings, check load).
  • Ensure the load is correctly connected to the output terminals with proper polarity.
• Incorrect Readings:
  • Verify that the measurement leads are properly connected and not damaged.
  • Ensure the device is operating within its specified temperature range.
• PC Software Connection Issues:
