 How to use: 

 a. Push down on the switch click, then release, power, Beep sound, LCD all were about 2 seconds, then displays 00.0PSI 

 (Or 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 

 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. Click each Push down the switch can be converted units (PSI-> Bar -> PSI), LCD display instantly convert the pressure value, 

 e. Push switch for tread depth gauge, shown in units of mm tread depth value, 

 f. If the goal is not to measure, automatically shut down after about 30 seconds. 

 g. to promote the switch does not let go down about 2 seconds, manual shutdown.
