3. Veiligheidsmaatreëls
- The product does not include a battery. If the test lead or battery is not connected correctly, the device will not turn on.
- Vermy kortsluitings: Ensure that the tester is in good contact with the battery during tests to prevent short circuits, equipment damage, or battery overheating.
- Omgewingstoestande: Use this tester in a dry, well-ventilated area. To avoid equipment damage or inaccurate measurements, do not use it in humid or extreme-temperature conditions.
- Vermy High Voltage: Handle high-voltage batteries with care, and ensure that the tester's specifications are compatible with the type and voltage range of the battery being tested.
- Bergingsvoorwaardes: Store the tester in a dry, cool area when not in use. This helps prevent damage from moisture or high temperatures.
- Turn off the main power of the device before testing, and remove any keys or switches.
- Do not use the tester on batteries exceeding 48V. Testing batteries over 48V may damage the tester or cause personal injury.

4. Opstelling
Before use, ensure that any dirt or foreign substances on the positive and negative terminals of the battery are thoroughly cleaned to avoid affecting measurement accuracy. For optimal accuracy, fully charge the battery and allow it to rest for two hours before testing.
The battery tester can only be activated when voltage is above 6.5V and the positive and negative terminals are correctly connected. If the tester does not respond after these steps, consider recharging the battery or cleaning the terminals.
- Connect the Alligator Clips: Connect the red alligator clip to the positive (+) terminal of the battery and the black alligator clip to the negative (-) terminal. The tester will automatically power on.
- Kies batterytipe: Press the 'TYPE' button to select the correct battery type (STD, EFB, AGM, GEL) that matches your vehicle's battery.
- Select Test Standard: Press the 'D-STD' button to select the appropriate test standard (EN, IEC, SAE, CCA, DIN, AH).
- Enter CCA Value: Use the up/down arrow buttons to enter the Cold Cranking Amp (CCA) value corresponding to your battery. This value is usually found on the battery label.

5. Bedryfsinstruksies
Once the setup is complete, you can proceed with testing your battery.
- Begin toets: Press the 'TEST' button to initiate the battery test.
- View Resultate: Wait for 2 seconds. After this, the measurement result will display the battery voltage, resistance (I.R), State of Charge (SOC), and State of Health (SOH).
- Interpret SOH: The State of Health (SOH) indicates the battery's overall condition.
- SOH > 80%: UITSTEKEND
- SOH 60%–79%: GOED
- SOH 45%–59%: SLEG
- SOH < 44%: VERVANG (Replace battery as soon as possible)
- Interpret SOC: The State of Charge (SOC) indicates the current charge level of the battery. If the current charge is too low, the tester will indicate 'NEED CHARGE'.
- Return to Previous Step: Press the 'ESC' button to go back to the previous menu or measurement.
