4.1 Key Features

• LCD Display: Shows output voltage for +12V, -12V, +5V, -5V, +3.3V, +5V Standby (SB), and Power Good (PG) values.
• Audible Warning: A buzzer sounds and the corresponding value flashes if any parameter exceeds normal limits.
• Broad Compatibility: Supports ATX, BTX, ITX, TFX computer power supplies.
• Multiple Connectors: Includes jacks for 20/24-pin ATX, P4, P6, P8, Floppy, HDD, CDROM, and SATA.

5. Setup

Setting up the TECKEEN LCD Power Supply Tester is straightforward. Ensure your power supply is disconnected from the computer and any wall outlet before proceeding.

5.1 Connecting the Power Supply

1. Locate the main 20/24-pin ATX connector from your power supply.
2. Plug the power supply's 20/24-pin ATX connector into the corresponding jack on the power tester.
3. If testing other connectors (e.g., P4, P6, P8, SATA, Floppy, HDD), plug them into their respective jacks on the tester. You can test multiple connectors simultaneously.

6. Operation

Once the power supply is connected to the tester, you can begin the testing process.

1. Power On: Connect your power supply to a wall outlet and turn it on (if it has a switch). The tester will automatically power on.
2. Initial Check: Upon powering on, you should hear a single beep sound. The LCD display will illuminate and show various voltage readings. If there is no flickering on the display and no continuous buzzer sound, the power supply output voltages are generally normal.
3. Interpreting Results:
   • Normal Operation: The LCD displays stable voltage values for +12V, -12V, +5V, -5V, +3.3V, +5V SB, and PG.
   • Fault Detection: If a specific voltage signal is not detected, or if a detected voltage value is outside the normal operating range, you will hear a continuous long buzzer sound. Additionally, the corresponding voltage value or the PG value on the LCD will flash, indicating a power supply failure.

8. Troubleshooting

• No Display/No Power: Ensure the power supply is properly connected to the tester and is receiving power from the wall outlet. Check the power supply's own switch if applicable.
• Continuous Buzzer Sound and Flashing Values: This indicates a fault in the power supply. One or more voltage rails are outside acceptable limits, or the Power Good signal is incorrect. The power supply should be replaced or serviced by a qualified technician.
• Incorrect Readings: Double-check that all connectors are firmly seated in the tester. Ensure you are using the correct connectors for your power supply type.

9. Maintenance

The TECKEEN LCD Power Supply Tester requires minimal maintenance.

• Cleaning: Wipe the device with a soft, dry cloth. Do not use liquid cleaners or solvents.
• Storage: Store the tester in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
