SAFETY INSTRUCTIONS

This manual includes guidelines on the operation of your device and the precautions to follow for your own safety. Ensure it is read carefully before first use and keep it handy for future reference.

Risk of explosion and fire

  • A battery being charged can emit explosive gas.
  • The battery tester should only be connected to batteries with a rated output voltage of 6 V, 12 V and 24 V .
  • CAUTION: Reverse polarity will cause the fuse to blow and could cause permanent damage. Damage due to reverse polarity is not covered by our warranty.
  • If the car’s battery is disconnected, some management systems may be disabled.
  • Consult your vehicle manual for more information on installation.
  • Do not use the battery tester if the cord or terminals are damaged.
  • Do not use the battery tester if it has received a severe shock or has been damaged in any way.
  • Do not disassemble the device. Incorrect reassembly may result in a risk of electric shock or fire.

Acid projection hazard!

  • Wear appropriate safety glasses and clothing.
  • If your eyes or skin come into contact with battery acid, rinse the affected part of the body with plenty of water and seek immediate medical assistance.
  • Avoid flames and sparks. Do not smoke.
  • Protect the electrical contacts of the battery against shortcircuiting.
  • The device complies with European Directive.
  • The certificate of compliance is available on our website.
  • EAC conformity mark (Eurasian Economic Commission)
  • Material conforms to UK requirements. The UK Declaration of Conformity is available on our website.
  • The device is compliant with Moroccan standards.
  • The C م (CMIM) declaration of conformity is available on our website.
  • This product should be disposed of at an appropriate recycling facility. Do not dispose of domestic waste.
  • The recyclable product falls within waste sorting recommendations.

CONNECTING THE BATTERY TESTER

  1. Ensure that the area is well-ventilated before performing a test.
  2. Tester for 6 and 12 V batteries and test of the 12/24 V battery charging system (only 12 V on the START & STOP batteries).
  3. Before performing a test on the battery, make sure that the ignition and the consumers are switched off. Close all the doors and the boot.
  4. Make sure that the battery connections are clean. If necessary, clean them using a wire brush. Any presence of oxidation between the tester terminals and the battery connectors or between the battery connectors and the battery terminals reduces the effectiveness of the tester.
  5. Check that the tester has 6 x 1.5V batteries in the compartment.
  6. Connect the negative plug (black) to the negative terminal of the battery. Connect the positive plug (red) to the positive terminal of the battery.

DEVICE SETTINGS

ERROR CHARGE

| The battery exceeds 2000 CCA or 200 AH, or the clamps are not properly connected.

If neither of these two elements listed above are the cause, fully recharge the battery and test again. If the display remains the same, replace the battery.

  1. In each case, to display the battery health status (SOH) and charge status (SOC), press to scroll through the results.
  2. Press «ENTER» to return to the home screen. Press «ENTER» again to access the main menu.

TEST OF THE ALTERNATOR CHARGING SYSTEM

  1. Press «SYSTEM TEST» and the following screen appears
  2. Make sure all vehicle consumers are switched off (lights, air conditioning, radio, etc.).
  3. Start the engine. One of these three results appears
