LCD Tire gauge for Automobiles vechicle motocycle tyre meter electronic meter 

1. Product introduction
This product is a portable car tire pressure measuring tools. Pressure is the most important indicator of tires, too high or too low pressure shortens the life, and even dangerous. Tire pressure monitor at any time in order to ensure the safety and reducing the risk of bursting of accidents for tires.
2. tire pressure monitoring principled
High precision pressure sensor device can handle a fair-time data acquisition for the band, after ad module is converted into digital signal and processed by mcu (central control), after the measured data is displayed on the LCD screen.
3. how to know the normal car tire
According to the different model or different makes of car, tire standard is definitely different. In general, it can be found by the following:
A. Car manual;
B. The tag on the side of the cabin door (close to b-pillar);
C. The drawer of the cabin door;
D. The small door of the fuel tank;
E. Car tire pressure is close to the door pillar or on the fuel tank cap or on the side of the co-pilot's door

5. How to use the tire gauge
1. Press the button to start digital tire pressure gauge, then press again to select pressure unit psi, bar, kPa.
2. addresses the gauge valve valve, press down the power to ensure no leakage, and take two or three seconds, the LCD displays the tire pressure values.
3. again when you need to test, long press the button for 3 seconds to turn it off, and then restart the gauge and select a pressure unit
4. Once you finished the measuring work, long press the button for 10 seconds to turn it off, or wait for 1 minute off automatically
