It will automatically turn on when it is powered on for the first time, the blue backlight will be on when it is turned on, and the LCD will display the actual pressure value after 1 second. 2. Long press the power button to turn on/off, the blue backlight will be on after turning on. The air pressure unit is the air pressure unit when the machine was turned off last time. Short press the power button to cycle through the air pressure units, and short press the setting key to view the set target air pressure value. In this mode, press the SET key to set the target value cyclically. After viewing or setting the target value, there is no button operation and the actual air pressure value will be displayed after 3 flashes, or the actual air pressure value will be displayed after short pressing K1 once. 3. Setting values in four unit modes: a) Unit: PSI Range: 3.0PSI-150PSI Adjustable accuracy: 1.0PSI b) Unit: BAR Range: 0.2BAR-10.3BAR Adjustable accuracy: 0.1BAR c) Unit: KPa Range: 2.0KPa-1030 (display A03) KPa Adjustable accuracy: 10KPa d) Unit: Kg/cm Range: 0.2Kg/cm-10.5Kg/cm Adjustable accuracy: 0.1Kg/cm 4. There is no key operation or pumping operation in the middle of the machine after starting up (the detected air pressure value is less than 20 KPa) It will automatically shut down after 2 minutes. 5. The air pump can only work when the air pump switch is pressed in the actual air pressure display mode.
