3. Safety Information

Always observe the following safety precautions when using the AUTOOL BT260 to prevent injury or damage to the tool or vehicle:

• Wear appropriate eye protection when working on vehicle electrical systems.
• Ensure the vehicle's ignition is off before connecting or disconnecting the tester, unless specific test procedures require otherwise.
• Avoid touching hot engine parts or moving components.
• Do not use the tester if the cables or probe tip are damaged.
• Keep the tester away from water, oil, and grease.
• Never apply voltage to the probe tip when the tester is connected to the vehicle's battery and the power switch is pressed, as this can damage the unit.
• The BT260 is designed for 6V, 12V, and 24V systems. Do not use it on systems outside this voltage range.

4. Setup

Before using the AUTOOL BT260, ensure it is properly assembled and connected to a power source.

1. Connect the Probe Tip and Power Cord: Insert the probe tip into the main unit and securely connect the power cord to the base of the tester.
2. Connect Electricity Supply: Attach the red battery clamp to the positive (+) terminal of the vehicle's battery and the black battery clamp to the negative (-) terminal or a suitable chassis ground. The tester will power on automatically.

5. Operating Instructions

5.1. Voltage Test

To perform a voltage test:

1. Ensure the BT260 is powered on and connected to the vehicle's battery.
2. Point the probe tip to the desired circuit point (positive or negative).
3. The BT260's display will show the voltage of the circuit point. The LED lights on the probe will indicate polarity (red for positive, green for negative).

5.2. Resistance Test

To test for resistance or continuity:

1. Connect the battery clips to a metal part of the car (ground).
2. Point the probe tip to the electric circuit or component you wish to test.
3. The BT260 will display the resistance value. A reading of "OL" indicates an open circuit (no continuity), while a numerical value indicates continuity and resistance.

5.3. Changing Language Settings

The BT260 supports multiple languages. To change the language:

1. Press the function key (yellow button on the body of BT260) 3 times to navigate to the loudspeaker icon.
2. Then, press and hold the upward button, and simultaneously press the function key 5 times to enter the "Language" menu.
3. Press the function key to select your desired language.
4. Press and hold the function key for 3 seconds to save the language setting.
5. Press the function key once to return to the main menu.
