3. Opsætning
The V200 is powered by the vehicle's 12V-24V battery. Connect the red alligator clip to the positive (+) terminal and the black alligator clip to the negative (-) terminal of the vehicle battery. Alternatively, use the provided cigarette lighter adapter for power.
3.1 Strømforsyning til enheden
- Batteriforbindelse: Sæt den røde clamp til den positive batteripol og den sorte clamp til den negative batteripol.
- Cigarette Lighter Connection: Insert the cigarette lighter adapter into the vehicle's 12V accessory socket.

4. Driftstilstande
The V200 supports four primary working modes, easily switchable with a single button press.
- DC bindtage Test: Detects the DC voltage value of the circuit under test with 0.1V resolution.
- AC Voltage Test: Detects Max/Min voltage, frequency, and duty cycle of the AC circuit.
- Modstandstest: Measures resistance between the probe tip and the auxiliary ground lead.
- Diode test: Determines the operation and conductivity of diode assemblies.

5. Nøglefunktioner
5.1 Polarity Identification
The V200 automatically identifies circuit polarity. A red LED indicates a positive connection, while a green LED indicates a negative connection. No LED indicates an open circuit.

5.2 Komponentaktivering
This feature allows you to activate components (e.g., lights, motors, relays) by supplying power or ground directly from the probe, aiding in troubleshooting. Use caution to avoid damaging components by applying incorrect polarity or excessive current.

5.3 Continuity, Sensor/Signal Circuit Test
Perform continuity tests, check sensor states, and verify signal integrity within circuits. The tool can also help locate short circuits and bad grounds.
6. Sikkerhedsfunktioner
6.1 Overbelastningsbeskyttelse
The V200 features a built-in 8-amp circuit breaker. In case of an overload, the device will automatically shut down to protect itself and the tested components. A beep warning will also occur.

8. Vedligeholdelse
To ensure the longevity and optimal performance of your VDIAGTOOL V200, follow these general maintenance guidelines:
- Keep the device clean and free from dust, dirt, and moisture.
- Store the tester and its accessories in the provided sturdy case when not in use.
- Inspect cables and connectors regularly for any signs of wear or damage. Replace if necessary.
- Undgå at udsætte enheden for ekstreme temperaturer eller direkte sollys i længere perioder.
9. Fejlfinding
If you encounter issues with your VDIAGTOOL V200, consider the following:
- Enheden tænder ikke: Ensure secure connections to the vehicle's battery or cigarette lighter. Verify the vehicle's power source is active.
- Ingen læsning/Forkert læsning: Check that the probe tip is making good contact with the circuit. Ensure the correct operating mode is selected.
- Overbelastningsbeskyttelse udløst: If the device shuts down with a beep, it indicates an overload. Disconnect the probe, allow a few moments, and then reconnect. Reduce the load or verify the circuit's specifications before retesting.
- Skærmproblemer: If the screen is blank or unresponsive, try disconnecting and reconnecting the power source.
