Note: The product does not contain the battery because the aircraft cannot transport the battery. You need to purchase it yourself. Instructions: Brake fluid detection pen is based on the change in conductivity to determine the moisture change brake fluid. It shows clearly the extent of moisture contained by the light-emitting diode, high moisture content will lead to lower boiling point, affect braking performance. Red indicates the brake fluid needs immediate replacement, green represents good condition, yellow indicates the state is acceptable but soon replaced. LED Indicator Display: 1.The green 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.
