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

5. Fonksyon kle
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 Component Activation
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. Karakteristik sekirite
6.1 Pwoteksyon Surcharge
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. Antretyen
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.
- Evite ekspoze aparèy la nan tanperati ekstrèm oswa limyè solèy la dirèk pou peryòd pwolonje.
NAN. Depanaj
If you encounter issues with your VDIAGTOOL V200, consider the following:
- Aparèy pa limen: Ensure secure connections to the vehicle's battery or cigarette lighter. Verify the vehicle's power source is active.
- No Reading/Incorrect Reading: Check that the probe tip is making good contact with the circuit. Ensure the correct operating mode is selected.
- Pwoteksyon Surcharge Deklanche: 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.
- Pwoblèm ekran: If the screen is blank or unresponsive, try disconnecting and reconnecting the power source.
