Tightly press the tire valve with the tail end of the tire pressure gauge, that is, the number displays the highest value._x000D_3. Please keep the front vertical direction to measure the pressure with the tire pressure gauge, and read the tire pressure._x000D_4. Please check the tire pressure value (refer to the description of the car for this pressure value) and keep the tire pressure correct._x000D_5.After the reading is completed, press the pressure relief valve to let the pressure in the pressure gauge drain._x000D_6. After the measurement, re-lock the cap on the tire valve. 13?200PSI digital tire inflator, accuracy is within 1 PSI, support switchable 4 units( PSI/KPA/Bar/Kgf/cm^2), can be used to test things from bicycles to heavy trucks. 2Digital tire pressure gauge can display the test value of 2?3s for easy reading, with backlight function, can be read clearly even in the dark. Automatically switch off to save battery power if there is no operation within 15s. 3Support deflate and inflate function, side bleed valve helps to vent the air when there gets high pressure, when the air pressure is too low, just connect the air compressor and press the "inflate" button to start inflating the tires. 4The design of the double?head chuck make it easier to connect the tire valve. It helps extend tire life and improve fuel economy, reduce the burden on the vehicle and allows you enjoy a comfortable and smooth driving. 5With on/off key, when the air pressure enters, it automatically recognizes the air pressure and turns it on without manual operation.
