Accuracy improvement: 1. It can reach 0.1psi in psi unit mode 2. It can reach 0.01bar in bar unit mode 3. It can reach 1kpa in kpa unit mode 4. It can reach 0.01kg/cm in kg/cm unit mode 5. The reading can be freely converted after pressure measurement, which is convenient to use. LCD screen brightness enhancement: the use of high-brightness LCD screen and blue spotlights greatly enhance the screen brightness, making it clearer and more convenient to use at night. Instructions: 1. Turn on the tire pressure gauge, it will display "8.8.8" after turning on, and then lightly press the power button to complete the four types of PSI, BAR, KPA KG Conversion of units on the LED display. 2. Push the pressure measuring nozzle into the tire valve quickly and firmly, and keep it airtight and stop for one second. Pull out the tire pressure gauge and read the value. 1KG/CM2=14.2PSI 1KG/CM2=0.98BAR 1KG/CM2=98.0KPA 3. This product will automatically shut down after half a minute. Note: The pressure measurement function needs to be turned on again before each retest Specification: Product name: Digital display car tire pressure gauge Product size: 13.8 x 5.6 x 3 cm Product net weight: 58 grams Pressure range: 0-150PSI, 0-10bar, 0-1000KPA, 0-10kg/cm Optional pressure unit: PSI, BAR, KPA, KG/CM2 Resolution: 0.5PSI/0.05BAR Accuracy: +/-1.5psi Power supply: AG13*3 ON/0FF button, automatic manual shutdown
