4.1 ڈسپلے کو پڑھنا

• The tester features a dual-color IPS display. Typically, one color (e.g., red) indicates current (Amperes, A) and the other (e.g., blue) indicates voltage (Volts, V).
• The display shows the instantaneous voltage and current being drawn by the connected device.
• The device also detects power (Watts, W), which is calculated from voltagای اور موجودہ.

4.2 Understanding Measurements

• والیومtage (V): Represents the electrical potential difference. A stable voltage reading indicates a healthy power supply.
• موجودہ (A): Represents the flow of electrical charge. Higher current indicates faster charging (if supported by the device and charger).
• پاور (W): The rate at which electrical energy is transferred. Calculated as Voltage x Current.
• QC2.0/QC3.0 Identification: The tester can identify if the connected charger and device are utilizing Quick Charge protocols, which may result in higher voltage readings (e.g., 9V, 12V) during fast charging. Note that real-time data may vary slightly due to dynamic charging conditions.

5 دیکھ بھال

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

• صفائی: Wipe the device with a soft, dry cloth. Do not use liquid cleaners or solvents, as they may damage the display or internal components.
• ذخیرہ: ٹیسٹر کو براہ راست سورج کی روشنی اور انتہائی درجہ حرارت سے دور ٹھنڈی، خشک جگہ پر اسٹور کریں۔

6 خرابیوں کا سراغ لگانا

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

• No Display/No Readings:
  • Ensure the tester is firmly plugged into a working USB power source.
  • Verify that the connected device is drawing power (e.g., charging).
  • ایک مختلف USB پورٹ یا پاور سورس آزمائیں۔
  • Ensure the cable connecting your device to the tester is functional.
• غلط پڑھنا:
  • Ensure all connections are secure. Loose connections can lead to unstable readings.
  • Test with a known good charger and cable to verify baseline accuracy.
  • Note that some power sources or cables may have internal resistance affecting readings slightly.
• Device Not Charging Through Tester:
  • Check if the device's charging cable is properly connected to the tester's output port.
  • Ensure the power source is providing sufficient power.
  • Try connecting the device directly to the power source to confirm the device and cable are working.

If the problem persists, please contact Voktta customer support for further assistance.
