OPERATION OF THE 12V LED BATTERY/ALTERNATOR TESTER
BATTERY TEST
1. Connect the red clamp to the positive (+) terminal of the car battery, then connect the black clamp to the negative (–) terminal.
➠ The “Battery OK” LED (F) will light up if the battery voltage is at least 10 V.
2. Remove the black clamp from the negative (–) terminal of the car battery, then remove the red clamp from the positive (+) terminal.
BATTERY CONDITION DURING VEHICLE START
❗👉➨ NOTE: The battery must be fully charged.
1. Connect the red clamp to the positive (+) terminal of the car battery, then connect the black clamp to the negative (–) terminal.
2. Start the vehicle.
3. During the starting process, when the starter is operating, the message “Battery OK” is indicated. The LED (F) remains on if the voltage does not drop below 10 V.
➠ If the “Battery OK” LED (F) goes out, you should consult an automotive service workshop.
4. Remove the clamps in the reverse order.
ALTERNATOR TEST
1. Connect the red clamp to the positive (+) terminal of the battery, then connect the black clamp to the negative (–) terminal.
➠ Ensure the measuring device has a good connection to the battery.
2. Start the engine and switch on the headlights and the car radio.
➠ The “GOOD” LED (B) lights up if the alternator is in good condition and producing the correct voltage.
➠ If the “DEFECT” LED (A) lights up, the alternator output exceeds 14.8 V, which can cause battery electrolyte evaporation. The voltage regulator is likely faulty.
➠ If no LED lights up, this means the measured voltage is less than 13.8 V. The alternator may be defective.
BATTERY CHARGE LEVEL
1. With the engine off, turn the ignition key to the first position and switch on the headlights and the rear window defroster for approximately 1–2 minutes.
2. Switch off the headlights and remove the ignition key.
3. Now disconnect the negative (–) terminal of the car battery.
4. After 10 minutes, connect the red clamp to the positive (+) terminal of the battery, then connect the black clamp to the negative (–) terminal of the battery.
5. Depending on the battery charge level, the LED will indicate:
➠ FULLY CHARGED (C) – Fully charged
➠ HALF CHARGED (D) – Half charged
➠ MINIMAL CHARGE (E) – Minimal charge
Threshold Voltage Values for Each Measurement Interval
MAINTENANCE
CLEANING
➠ Do not use liquid cleaning agents.
➠ Do not use flammable cleaning agents.
➠ Do not immerse the device in water or allow liquids to spill on it.
➠ If necessary, clean the device with a light, damp, soft cloth.
