7. Leer resultados:
   • The LCD display will show the percentage of water content in the brake fluid.
   • Simultaneously, the LED indicators will provide a quick visual assessment:
     • BUENO (LED verde): Water content is below 1% (0.1% - <1%). Brake fluid is in good condition.
     • WARNING (Yellow LED): Water content is between 1.5% and 2.5%. Brake fluid quality is deteriorating; consider replacement soon.
     • STOP (Red LED): Water content is 3.0% or greater (>4%). Brake fluid is severely contaminated and requires immediate replacement.
     • LOW BAT (Red LED): Indicates low battery power. Replace batteries for accurate readings.
