Instructions: 1. the green LED lights = water content in the brake fluid H2O 2. the yellow LED lights = brake fluid water content H2O = 1.5% to 3%, can continue to use, test again six months later 3. the red LED lights = water content in the brake fluid H2O> 3%, can not continue to use the brake fluid needs to be replaced Red LED: change brake fluid 4. LED red flashing: battery replacement 5. LED yellow: low moisture content, check again in six months 6. LED green: brake fluid lines / cell row Technical parameters: Green: Battery OK, that is, brake fluid does not contain water Green / yellow: brake oil in water content of less than 1%, better brake fluid performance, ease of use. Green / yellow / yellow: brake oil in water content of about 2%, brake fluid can continue to use. Green / yellow / yellow / red: brake oil in water content of about 3%, the proposed replacement of brake fluid. Green / yellow / yellow / red / red: brake oil in water content of at least 4%, the brake fluid must be replaced immediately responsible for very dangerous. Attention : 1.
