 How to use: 

 a. key boot, Beep sound, LCD all were about 2 seconds, then displays 00.0PSI (or the 000 other units), 

 b. the tire pressure and tire-bit aligned and pressed into the air, the pressure stability of about 2 seconds, or hear the "Beep" sound, 

 Instantly displays the correct measure of the number 

 c. the tire gauge and into the air spaces separated and re-measure the new pressure value, displays the new pressure value, 

 d. can be key conversion units (PSI-> Bar-> KPA-> Kg/cm2-> PSI), LCD display instantly convert the pressure value, 

 e. the number shown for about 10 seconds, then LCD back to "0", if the goal is not to measure, 

 Off automatically after about 20 seconds. Press and hold key for 2 seconds, manual shutdown.
