3. Enfòmasyon sou Sekirite
Always observe the following safety precautions when using the AUTOOL BT260 to prevent injury or damage to the tool or vehicle:
- Mete pwoteksyon pou je ki apwopriye lè w ap travay sou sistèm elektrik machin nan.
- 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.
- Pa janm aplike 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 ranje.
4. Enstalasyon
Before using the AUTOOL BT260, ensure it is properly assembled and connected to a power source.
- 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.
- Connect Electricity Supply: Tache cl batri wouj laamp 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.

5.1. Vòltage Tès
Pou fè yon voltage tès:
- Ensure the BT260 is powered on and connected to the vehicle's battery.
- Point the probe tip to the desired circuit point (positive or negative).
- 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:
- Connect the battery clips to a metal part of the car (ground).
- Point the probe tip to the electric circuit or component you wish to test.
- 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.
