Configuració
Before using the MP0514A tester, ensure the vehicle's ignition is off and the engine is not running. Prepare the battery terminals by cleaning any corrosion to ensure a good electrical connection.
- Locate your vehicle's 12V battery.
- Identify the positive (+) and negative (-) terminals. The positive terminal is usually larger and marked with a plus sign, while the negative terminal is marked with a minus sign.
- Connect the RED alligator clamp of the tester to the POSITIVE (+) battery terminal.
- Connect the BLACK alligator clamp of the tester to the NEGATIVE (-) battery terminal.
- Assegureu-vos tant clamps are securely attached to the battery terminals to prevent inaccurate readings or disconnections during testing.

Instruccions de funcionament
The MP0514A tester performs two main functions: battery state of charge testing and alternator/charging system analysis.
Battery State of Charge Test:
This test assesses the current charge level of your 12V battery.
- Ensure the tester is connected to the battery with the vehicle's engine OFF.
- Observe the LCD display for the battery voltage lectura.
- Refer to the LED indicators on the left side of the tester (labeled "STATE OF CHARGE"):
- COMPLET: La bateria està completament carregada.
- MITJÀ: Battery has a moderate charge.
- BAIX: Battery charge is low, consider charging.
- BUIT: Battery is critically low or discharged.

Alternator / Charging System Test:
This test evaluates the performance of your vehicle's alternator and charging system.
- With the tester still connected to the battery, start the vehicle's engine and keep it running.
- Observe the LCD display for the charging voltage lectura.
- Refer to the LED indicators on the right side of the tester (labeled "Alternator"):
- ALTA: Alternator output is too high (potential overcharging).
- BO: Alternator is functioning correctly and charging the battery optimally.
- DEAD: Alternator is not producing sufficient charge.
- REVERSA: Indicates incorrect polarity connection (if lit during initial connection).

Manteniment
To ensure the longevity and accurate performance of your MP0514A battery tester, follow these simple maintenance guidelines:
- After each use, wipe the tester body and clamps with a clean, dry cloth to remove any dirt, grease, or battery acid residue.
- Inspect the alligator clamps and cable for any signs of damage, fraying, or corrosion. Replace if necessary.
- Store the tester in a dry, cool place, away from direct sunlight and extreme temperatures.
- Do not immerse the tester in water or any other liquids.
Resolució de problemes
If you encounter issues while using the MP0514A tester, refer to the following guide:
a) LCD screen does not turn on when connected to batteries:
- Check for loose connections between the battery clamps and the battery posts. Ensure a firm connection.
- Verify polarity: The red clamp must be connected to the positive (+) post and the black clamp a la publicació negativa (-).
b) LCD screen displays "LO" or "HI":
- The tester's voltagEl rang és de 4-20 volts DC.
- "LO" indicates the battery voltage is below 4 volts DC.
- "HI" indicates the battery voltage està per sobre de 20 volts DC.
c) Alternator side LED indicators do not turn on during alternator test:
- Ensure the vehicle's engine is running during the alternator test.
- If the alternator output is below 13.6 volts DC, the LEDs may not illuminate, indicating a potentially low alternator output. Inspect the alternator for issues.
d) LCD screen value is fluctuating:
- The tester is powered directly by the battery being tested. A weak battery may cause unstable voltage readings on the LCD.
e) LCD screen does not turn on, but the Red "REVERSE" LED is lit:
- This indicates incorrect polarity connection. Disconnect the clamps and reconnect them correctly (Red to +, Black to -).

Consells per a l'usuari
- For the most accurate readings, ensure the battery terminals are clean and free of corrosion before attaching the clamps.
- When testing the alternator, make sure all major electrical accessories (headlights, radio, AC) are turned off to get a baseline reading of the alternator's output under normal load.
- If the battery consistently shows "LOW" or "EMPTY" even after charging, it might be time to consider replacing the battery.
