3. Bediening
3.1 FOXWELL NT604 OBD2 Scanner Operation
The NT604 scanner connects to your vehicle's On-Board Diagnostics II (OBD-II) port to access vehicle system information.
- Zoek de OBD-II-poort: De OBD-II-poort bevindt zich meestal onder het dashboard aan de bestuurderskant.
- Sluit de scanner aan: Plug the NT604's diagnostic cable into the vehicle's OBD-II port. The scanner will power on automatically.
- Vehicle Communication: The scanner will attempt to establish communication with the vehicle's ECU (Engine Control Unit). Follow on-screen prompts.
- Hoofdmenunavigatie: Use the navigation buttons (up, down, left, right, OK, ESC) to select desired functions from the main menu. Common functions include:
- Codes lezen: Retrieves Diagnostic Trouble Codes (DTCs) from the vehicle's systems.
- Codes wissen: Erases DTCs from the vehicle's memory. Note: Clearing codes does not fix the underlying problem. Address the issue before clearing codes.
- Actuele gegevens: Displays real-time sensor data from the vehicle.
- Bevroren beeld: Legt een momentopname vast van de bedrijfsomstandigheden van het voertuig op het moment dat een foutcode werd gegenereerd.
- I/M-gereedheid: Controleert de status van emissiemonitoren.
- System Diagnostic: Accesses specific vehicle systems like Engine, ABS, SRS (Airbag), and Transmission for detailed diagnostics.

3.2 FOXWELL BT100 Pro Battery Tester Operation
The BT100 Pro is designed for testing 12V automotive batteries. It can perform tests both in-vehicle and out-of-vehicle.
- De batterij voorbereiden: Zorg ervoor dat de accupolen schoon en vrij van corrosie zijn.
- Sluit de tester aan:
- Sluit de rode cl aanamp naar de positieve (+) accupool.
- Sluit de zwarte cl aanamp naar de negatieve (-) accupool.
- De tester wordt automatisch ingeschakeld.
- Selecteer testtype:
- In-Vehicle Test: For batteries installed in the vehicle.
- Out-of-Vehicle Test: For standalone batteries.
- Selecteer batterijtype: Choose the correct battery type (e.g., Regular Flooded, AGM Flat Plate, AGM Spiral, GEL) from the menu. Incorrect selection may lead to inaccurate results.
- Enter CCA Rating: Voer de koudstartwaarde in. Amps (CCA) rating found on the battery label.
- Test uitvoeren: The tester will perform the analysis and display results such as:
- Deeltage
- Gemeten CCA
- Interne weerstand
- Gezondheidstoestand (SOH)
- Laadstatus (SOC)
