3. تنظیم او پیوستون

Follow these steps to connect and power on your USB Tester Meter A3.

Connecting the Tester:

1. Identify the appropriate input port (USB-A, Type-C, or Micro USB) on the tester for your power source (e.g., wall charger, power bank).
2. Connect the power source to the tester's input port.
3. Connect your device (e.g., smartphone, tablet) to the tester's output port (USB-A or Type-C) using a compatible cable.

Important Notes for Type-C Connections:

• If the display does not light up when using a Type-C connection, try flipping the Type-C cable and re-inserting it. Type-C protocols can be one-sided, and this is normal operation, not a malfunction.
• When using PD (Power Delivery) power, ensure both the charger and the charging device support quick charge protocols. If a PD power source is not connected to a fast-charge device, the tester may not power on by default.
• For some Type-C connections, using the included Type-C accessory (adapter) may be necessary to ensure proper connection and display functionality.
