4. Funtzionamendu moduak
The V200 supports four primary working modes, easily switchable with a single button press.
- DC bolumenatage Proba: Detects the DC voltage value of the circuit under test with 0.1V resolution.
- AC Boltage Proba: Detects Max/Min voltage, frequency, and duty cycle of the AC circuit.
- Erresistentzia proba: Measures resistance between the probe tip and the auxiliary ground lead.
- Diodo proba: Determines the operation and conductivity of diode assemblies.

5. Funtzio nagusiak
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 Osagaien Aktibazioa
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. Segurtasun Ezaugarriak
6.1 Gainkargaren babesa
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.

9. Arazoak
If you encounter issues with your VDIAGTOOL V200, consider the following:
- Gailua ez da pizten: Ensure secure connections to the vehicle's battery or cigarette lighter. Verify the vehicle's power source is active.
- Irakurketarik ez/Irakurketa okerra: Check that the probe tip is making good contact with the circuit. Ensure the correct operating mode is selected.
- Gainkarga babesa aktibatuta: 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.
- Pantailaren arazoak: If the screen is blank or unresponsive, try disconnecting and reconnecting the power source.
