操作手順

Once connected, the Voktta USB Tester provides comprehensive real-time data. Here's how to utilize its features:

• Real-time Detection: The tester continuously displays voltage (V), current (A), power (W), capacity (mAh), energy (mWh), time (T), resistance (Ω), and temperature (°C).
• ディスプレイの向き: The 0.96-inch IPS display can be connected in two directions, offering a 160° wide view読みやすさを最適にするために角度を調整します。
• 表示モードの変更: Press the physical button located on the side of the tester to cycle through different display interfaces. Each interface may present a different combination or layout of measurement parameters.
• パワーオフメモリ機能： The tester is equipped with a power-off memory function. When the power supply to the mobile device is interrupted, the accumulated capacity (mAh) and energy (mWh) data are stored. This feature is particularly useful for measuring the total energy capacity of mobile power sources over time.
• Quick Charge Protocol Identification: The tester supports the identification of Quick Charge protocols, specifically QC2.0 and QC3.0, allowing you to verify if your device is fast charging.

メンテナンス

To ensure the longevity and accurate performance of your Voktta USB Tester, follow these maintenance guidelines:

• クリーニング： Use a soft, dry cloth to clean the exterior of the device and the display screen. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the plastic and screen.
• ストレージ： テスターは、直射日光、極端な温度、高湿度を避け、涼しく乾燥した場所に保管してください。
• 取り扱い： Handle the device with care. Avoid dropping it or subjecting it to strong impacts, which could damage internal components or the display.
• 分解： Do not attempt to disassemble or repair the device yourself. Unauthorized disassembly voids the warranty and may lead to damage or injury.

トラブルシューティング

If you encounter issues with your Voktta USB Tester, refer to the following common problems and solutions:

• No Display or Screen Not Lighting Up:
  • Ensure the tester is securely connected to a functional USB power source.
  • Verify that the device being charged is also properly connected and drawing power.
  • Try connecting the tester to a different USB port or power adapter.
• 不正確な読み取り:
  • Check all connections to ensure they are firm and stable. Loose connections can lead to fluctuating or incorrect readings.
  • Test with a different USB cable, as faulty cables can significantly impact charging performance and measurement accuracy.
  • Test with a different power source or load device to isolate if the issue is with the tester or other components.
• Capacity/Energy Data Not Stored:
  • The power-off memory function stores data when the power supply is completely disconnected. Ensure the device is fully powered off or disconnected from the power source for data to be saved.
  • If the power is only momentarily interrupted, the data might not be saved.
• テスター経由でデバイスが充電されない:
  • The tester itself should not prevent charging. If your device is not charging, first bypass the tester to confirm the power source and cable are working.
  • If the device charges without the tester, ensure the tester is not damaged and is properly connected.
