6. ઓપરેટિંગ મોડ્સ
The BT280 offers several operating modes for comprehensive electrical system diagnostics. Navigate through the modes using the directional buttons and 'OK' button on the device.
6.1. Smart Test Mode
In Smart Test mode, the device automatically identifies the voltage, resistance, and polarity (positive or negative) of the component being tested. A green indicator means negative, and a red indicator means positive.

Figure 6: Smart Test mode automatically identifies voltage, resistance, and polarity.
6.2. Multimeter Mode
This mode provides comprehensive multimeter functions, allowing you to quickly test DC voltage, resistance, diode, current, and frequency in the circuit system. The device also features a built-in flashlight for convenience.

Figure 7: Multimeter mode showing voltage, resistance, diode, current, and frequency measurements.
6.3. Oscilloscope Mode
The Oscilloscope mode allows you to display the parameter curve diagram of the tested component, such as voltage, frequency, and time. This is useful for visualizing electrical signals. Adjust the voltage value using the up and down keys (test range 1V-49V).

Figure 8: Oscilloscope mode displaying a square wave, showing voltage, frequency, and time parameters.
6.4. Relay Test Mode
This mode is designed to test the functionality of common automotive relays, including both 4-terminal and 5-terminal types. Connect the relay using the provided test lines as shown in the diagram.

Figure 9: Relay test interface and connection diagram for 4-terminal and 5-terminal relays.
6.5. Component Activation Mode
The Component Activation mode allows the BT280 to generate 'Active' signals to power and test various components such as lights, motors, and other on-board electronic devices. This helps in verifying component functionality directly.

Figure 10: Demonstrating component activation by powering an LED strip.
6.6. Injector Test Mode
This mode is specifically for testing fuel injectors. It can output different pulse signals to the injector, providing 4 distinct pulse modes to accurately detect the condition and performance of the injector.

Figure 11: Injector test mode showing different pulse options for comprehensive diagnosis.
6.7. 0-5V Power Supply Mode
The 0-5V Power Supply mode allows you to set a specific output voltage between 0-5V. This is useful for verifying the wiring condition of a tested component or for powering low-voltage circuits. The device is equipped with a voltage setting alarm that will activate if the output voltage deviates by more than 0.1V from the set value due to a short circuit or fault.

7. વપરાશકર્તા ટિપ્સ
- When using the Oscilloscope mode, ensure proper connection to avoid unexpected behavior. If testing negative signals, be aware that incorrect connections or signal types might cause issues with the vehicle's system.
- The BT280 is designed for ease of use, but always refer to the specific vehicle's service manual for detailed wiring diagrams and component specifications before testing.
- Keep the device's software updated by the factory. Users do not need to perform software upgrades independently; improper upgrades can damage the equipment.
8. મુશ્કેલીનિવારણ
- ઉપકરણ ચાલુ થતું નથી: ખાતરી કરો કે બેટરી clamps are securely connected to the correct terminals (red to positive, black to negative) of a 9V-30V vehicle battery. Check for loose connections in the power supply line.
- અચોક્કસ વાંચન: Verify that the probe tip is making good contact with the component. Ensure the device is in the correct operating mode for the measurement you are trying to take. Clean the probe tip if necessary.
- Oscilloscope mode issues: If the oscilloscope is not displaying a stable waveform or causing vehicle issues, double-check the connections and ensure the signal being tested is within the device's capabilities. Consult a professional if unsure about complex signals.
- ભાગtage alarm triggers frequently: This indicates a potential short circuit or fault in the component or wiring being tested. Disconnect immediately and inspect the circuit for damage or incorrect connections.
9. જાળવણી
- સફાઈ: ઉપકરણને સોફ્ટ સાથે સાફ કરો, ડીamp કાપડ ઘર્ષક ક્લીનર્સ અથવા સોલવન્ટનો ઉપયોગ કરશો નહીં.
- સંગ્રહ: Store the BT280 in its original carrying case in a dry, cool place away from direct sunlight and extreme temperatures.
- તપાસ ટીપ: Keep the probe tip clean and free from debris to ensure accurate contact.
- કેબલ્સ: Inspect all cables and connectors regularly for signs of wear or damage. Replace any damaged components immediately.
