5. Opsætning og tilslutning
The KWS-DC28 is designed for inline measurement. Follow these steps to connect the device:
- Identificer input og output: The device typically has a male connector on one end (input) and a female connector on the other (output). Ensure you connect the power source to the input and the load (device to be tested) to the output.
- Tilslut strømkilde: Plug the male connector of the KWS-DC28 into your DC power source (e.g., USB charger, power adapter).
- Tilslut belastning: Plug the device you wish to test (e.g., mobile phone, USB fan) into the female connector of the KWS-DC28.
- Bekræft visning: Once connected, the display should illuminate and show real-time voltage, nuværende og andre parametre.
Important: Always ensure the voltage and current of your power source and load are within the KWS-DC28's specified operating ranges (DC 4-30V, 0-12A).
6. Betjening
Once connected, the KWS-DC28 operates automatically, displaying real-time data. There are no complex settings or buttons for basic operation.
- Overvågning i realtid: The display continuously updates with current voltage-, strøm- og effektaflæsninger.
- Accumulated Data: The device automatically accumulates charge (mAh) and energy (mWh) over time. This data is useful for testing battery capacities or device consumption over a period.
- Resetting Accumulated Data: To reset the accumulated mAh and mWh values, disconnect the power from the KWS-DC28 for a few seconds, then reconnect it. The values will reset to zero.
The small button on the side (if present, not clearly visible in images but common for such devices) might be used to cycle through display modes or reset data. If your unit has a button, gently press it to observe its function. Typically, a short press cycles display, a long press resets accumulated data.
7. Vedligeholdelse
- Rensning: Brug en blød, tør klud til at rengøre enheden. Brug ikke slibende rengøringsmidler eller opløsningsmidler.
- Opbevaring: Opbevar enheden et køligt, tørt sted væk fra direkte sollys og ekstreme temperaturer.
- Håndtering: Undgå at tabe enheden eller udsætte den for kraftige stød.
8. Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Skærmen er tom | No power, incorrect connection, or voltage for lavt. | Ensure the power source is active. Check connections for correct polarity. Verify input voltage er inden for DC 4-30V. |
| Forkerte aflæsninger | Faulty connection, device malfunction. | Reconnect the device. Test with a known good power source and load. If problem persists, contact support. |
| Accumulated data not resetting | Device not fully powered off. | Completely disconnect the device from power for several seconds before reconnecting. |
| Enheden bliver varm | Operating near maximum current/power, poor ventilation. | Ensure adequate ventilation. Reduce load if possible. If overheating persists at normal loads, discontinue use and contact support. |
