4. Instruccions de funcionament
The TVA3006 features a user-friendly interface and a single button for navigation.
4.1 Interfície de pantalla principal
Upon connection, the main interface displays the following real-time parameters:
- Voltage (V): Vol actualtage lectura.
- Corrent (A): Actual amplectura d'època.
- Potència (W): Calculated power consumption.
- Work Timekeeping: Duration of the current measurement session.
- Temperatura: Temperatura interna del dispositiu.
- Direction of Current: Indication of current flow direction.
- Quantity of Electricity (mAh/mWh): Accumulated charge and energy.
- Capacitat: Measured capacitance.

4.2 Data Statistics Interface
The tester automatically records and displays statistical data:
- Dades en temps real: Current live readings.
- Maximum Value (Max): Highest recorded voltage, corrent i potència.
- Average Value (Ave): Volum mitjàtage, current, and power over the measurement period.
- Minimum Value (Min): Lowest recorded voltage, corrent i potència.
4.3 Funcionament del botó
The single button on the side of the tester allows for display control:
- Premsa curta: Cycles through different display screens (e.g., main interface, data statistics).
- Premsa llarga: Flips the display orientation. This is useful when the tester is inserted in a way that makes the screen difficult to read, allowing you to view data in the forward direction.
4.4 Actualització del firmware
The TVA3006 supports firmware upgrades to enhance functionality and improve performance. Connect the tester to a computer via its Type-C port and follow the instructions provided by SEQURE for the upgrade process.

5. Manteniment
To ensure the longevity and optimal performance of your SEQURE TVA3006 USB Tester:
- Mantingueu el dispositiu sec i allunyat de la humitat.
- Clean the screen and body with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
- Store the tester in a cool, dry place when not in use.
- Eviteu deixar caure o sotmetre el dispositiu a forts impactes.
6. Solució De Problemes
- Sense pantalla: Ensure the tester is properly connected to a power source and a device. Check if the power source is active.
- Lectures inexactes: Verify that all connections are secure. Ensure the device being tested is functioning correctly. If testing PD, confirm a load is connected.
- Screen Not Flipping: Ensure you are performing a long press on the button. A short press will cycle through display modes.
