Impostare

1. Identificare le porte: Locate the USB-A input, Type-C input, USB-A output, and Type-C output ports on the device. The input ports are typically marked as "INPUT" and output as "OUTPUT" on the display side.
2. Collegare la fonte di alimentazione: Plug the USB-A or Type-C input of the power meter into your power source (e.g., wall charger, power bank, computer USB port).
3. Connetti dispositivo: Plug the device you wish to test or charge (e.g., smartphone, tablet, USB fan) into the corresponding USB-A or Type-C output port of the power meter.
4. Accensione: The device will typically power on automatically once connected to a power source and display readings.

Istruzioni per l'uso

The DEWIN USB Power Meter provides real-time data on its 0.96-inch HD IPS color LCD screen. A single interface displays voltage, current, accumulated energy, power, and synchronization time.

Comprensione del display

Figura 5: Detailed breakdown of the information displayed on the meter's screen, including voltage (V), current (A), power (W), capacity (mAh), time (T), and capacity groups (1-9).

• Voltage(V): Visualizza il volume correntetage viene fornito.
• Corrente (A): Shows the current flowing through the device.
• Potenza (W): Indicates the real-time power consumption (Voltagex Corrente).
• Capacità (mAh): Accumulates the total charge transferred over time.
• Time (T): Tracks the duration of the measurement.
• Gruppi di capacità (1-9): Allows for storing and recalling up to 9 sets of accumulated capacity data. Refer to the device's physical buttons (if any) for cycling through or resetting these groups.

Scenari di connessione

Figura 6: This diagram shows how to connect the USB Power Meter to various devices and power sources for testing and charging.

The meter can be used to test a wide range of devices, including mobile phones, tablets, power banks, USB fans, USB lights, and various chargers (ordinary USB chargers, Type-C chargers, car chargers).

Caratteristiche protettive

The integrated electronic switch element ensures safe detection. The output is automatically turned off to protect your device from damage if abnormal conditions are detected. The device can also store data in case of a sudden power outage.

Figura 7: The meter features warning pages that alert the user if measured voltage or current values exceed or fall below predefined thresholds.

Manutenzione

• Pulizia: Per pulire il dispositivo, utilizzare un panno morbido e asciutto. Non utilizzare detergenti liquidi o solventi.
• Magazzinaggio: Conservare il dispositivo in un luogo fresco e asciutto, lontano dalla luce solare diretta e da temperature estreme.
• Gestione: Avoid dropping or subjecting the device to strong impacts, as this may damage internal components or the screen.

Risoluzione dei problemi

• Nessuna visualizzazione:
  • Ensure the meter is properly connected to a power source (input).
  • Ensure a device is connected to the output port and drawing power. The display may not light up if no load is detected.
• Letture imprecise:
  • Verify that all connections are secure and free from debris.
  • Test with a different power source or device to rule out external factors.
  • Assicurarsi che il dispositivo funzioni entro il volume specificatotage e intervalli di corrente.
• Dispositivo non in carica:
  • Check the power meter's display for any error messages or warning indicators (refer to Figure 7).
  • Bypass the power meter and connect your device directly to the power source to confirm the power source and device are functional.
  • Ensure the cables used are in good condition and support the required current/voltage.

Informazioni sulla sicurezza

• Non smontare o modificare il dispositivo. Modifiche non autorizzate possono causare malfunzionamenti o scosse elettriche.
• Tenere il dispositivo lontano da acqua, umidità e umidità elevata.
• Avoid exposing the device to extreme temperatures or direct heat sources.
• Use the device only within its specified voltage and current ranges to prevent damage to the meter or connected devices.
• This device is intended for informational and testing purposes. Do not use it as a primary protective measure for critical systems.
