4. Moduri de operare
The V200 supports four primary working modes, easily switchable with a single button press.
- DC Voltage 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.
- Test de rezistență: Measures resistance between the probe tip and the auxiliary ground lead.
- Test de diodă: Determines the operation and conductivity of diode assemblies.

5. Funcții cheie
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 Activarea componentelor
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.

- Evitați expunerea dispozitivului la temperaturi extreme sau la lumina directă a soarelui pentru perioade prelungite.
9. Depanare
If you encounter issues with your VDIAGTOOL V200, consider the following:
- Dispozitivul nu pornește: Ensure secure connections to the vehicle's battery or cigarette lighter. Verify the vehicle's power source is active.
- Fără citire/Citire incorectă: Check that the probe tip is making good contact with the circuit. Ensure the correct operating mode is selected.
- Protecție la suprasarcină declanșată: 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.
- Probleme legate de ecran: If the screen is blank or unresponsive, try disconnecting and reconnecting the power source.
