LED Indicator Display:
1. green LED = water content in brake fluid H2O Less than 1.5%, brake fluid qualified
2. yellow LED brake fluid indicators water content H2O = 1.5% to 3%, can continue to use, the test again after six months
3. LED red LED = water content in brake fluid H2O Greater than 3%, can not continue to use the brake fluid must be replaced
Red LED: brake fluid replacement
4. red LED flashing: battery replacement
5. yellow LED: low moisture content, check again in six months
6. green LED: brake line fluid / mobile line
Technical specifications:
Green: Battery IN ORDER, that is, the brake fluid does not contain water
Green / yellow: brake oil in water content less than 1%, better brake fluids performance, ease of use.
Green / yellow / yellow: brake oil in water content about 2%, the 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 not less than 4%, the brake fluid must be immediately replaced with the responsibility for very dangerous.
