Configuració
- Connecteu la font d'alimentació: Plug the integrated USB-A or USB-C input cable of the VOLTCRAFT PM-41 into your USB power source (e.g., wall charger, power bank, computer USB port). The tester's display should illuminate, showing initial voltage lectures.
- Connect the Device to be Tested: Connect the USB device you wish to test (e.g., smartphone, tablet, USB fan) to one of the output ports on the VOLTCRAFT PM-41 (either USB-A or USB-C, depending on your device's cable).
- Ensure a Load: For accurate current and power measurements, ensure that the connected USB device is actively drawing power (i.e., it is charging or operating). If no load is connected, the current reading will be zero.
The tester will automatically begin displaying real-time measurements once connected.
Instruccions de funcionament
The VOLTCRAFT PM-41 features a clear display and two control buttons: 'Mode' and 'Read'.
Display Readings:
- VDD (V): Mostra el volum actualtage en Volts.
- Cur (A): Displays the current draw in Amperes.
- mAh: Displays the accumulated electrical charge (capacity) in milliampere-hours. This value accumulates over time.
- Hora: Displays the elapsed time since the measurement began.
- Wh: Displays the accumulated electrical energy in Watt-hours. This value accumulates over time.
- Equivalent Resistance (Ω): This value is typically calculated from voltage and current (V/A) and may be displayed in some modes.
Funcions del botó:
- Botó de mode: Press this button to cycle through different display modes or measurement parameters.
- Read Button: Press and hold this button for a few seconds to reset accumulated data such as mAh, Wh, and Time.
Nota: The tester automatically starts measuring when a power source and a load are connected. Ensure stable connections for accurate readings.
Manteniment
- Neteja: Use a soft, dry cloth to clean the device. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the casing o pantalla.
- Emmagatzematge: Store the VOLTCRAFT PM-41 in a cool, dry place, away from direct sunlight and extreme temperatures. Keep it away from dust and moisture.
- Manipulació: Avoid dropping the device or subjecting it to strong impacts, which can damage internal components.
Resolució de problemes
| Problema | Causa possible | Solució |
|---|---|---|
| La pantalla no s'il·lumina. | No power source connected or power source is faulty. | Ensure the USB tester is properly connected to a working USB power source. Try a different power source. |
| Current (Cur) reading is 0.00A. | No USB device connected or the connected device is not drawing power. | Connect a USB device that requires power (e.g., a phone that needs charging). Ensure the device is turned on or actively charging. |
| Lectures inexactes. | Loose connections, faulty cables, or device malfunction. | Check all connections for tightness. Try different USB cables. If the problem persists, the tester or the connected device might be faulty. |
| mAh/Wh/Time values are not resetting. | 'Read' button not pressed correctly. | Press and hold the 'Read' button for a few seconds to reset the accumulated data. |
