Specification for LCD inflatable paddle board/surfboard inflator
I.Introduction to main functions:
1.The default display upon startup is the last set air pressure value,
2.Measurement range:0~22psi,measurement accuracy:±0.5PSI
3.Resolution:0.01 PSI
4.Temperature range:-10 to 50 degrees Celsius
5.5 buttons:PSI button,Bar button,start/stop button,+button,-button
6.Unit selection:Press the button to switch between units,PSI and Bar,
7.The+and-buttons can be used to preset the air pressure value,and the preset value will not be lost in case of power failure,
9.Panel display:Unit display,8888(four 8s)display for real-time inflation pressure value,preset pressure value display,no battery power status display
(When turned on,it blocks the display of three non-functional features:battery level,storage,and lights,which meets certain requirements.)
10.Powered by a 12V car battery,it displays all information upon power-on and automatically resets to the previous preset value of PSI
11.Backlight continuously on
12.The default preset value upon initial power-on is 10.0 PSI
II.Working status
(1)There is no power button.When powered on,the real-time digital display lights up,indicating that it has been turned on.The default preset air pressure is 10.0 psi for the first power-on,and it is necessary to customize the preset air pressure value;
There is no shutdown button.Disconnecting the cigarette lighter will shut down the device,and re-powering it will restore the preset values before shutdown.
Press the inflate button to start the air pump,and press the on/off button again to stop the air pump;when the air pressure reaches 0.68 psi,switch from the small motor to the large motor;long press the inflate button to force a switch to the large motor;during the operation of the air pump,pressing the inflate button will stop the air pump.
(2)Preset air pressure:
Press the+or-key to enter the preset state,and the digital display will show the last preset pressure;
Press and increment,with a step size of 0.5 psi/0.034 bar(continuous pressing for rapid increment);
Press and hold-decrement,with a step size of 0.5 psi/0.034 bar(continuous pressing for rapid decrement).The preset value will be automatically saved 1 second after the button is released,and the digital display will show the real-time air pressure value;
(3)After the settings are completed,press the power button to start inflating until the air pressure reaches the preset value,and then stop inflating.During the inflation process,pressing the pump button will stop the air pump.
(4)When the preset value is less than the actual air pressure of the air pump,the air pump cannot start inflating.
(5)Control working status of 2 motors:After pressing the air pump button,the small motor No.1 continues to work.When the actual air pressure reaches 0.68 psi,the small motor No.1 stops,and the large motor No.2 starts.The large motor No.2 continues to work until the air pressure reaches the preset value,and then it stops and does not work anymore.
When starting up,first activate the No.1 small motor.After inflating to 0.68 psi,the No.2 motor starts,and the No.1 small motor stops inflating.The No.2 large motor then inflates alone until reaching the set pressure value.If the machine stops halfway and the pressure is higher than 0.68 psi,the No.1 small motor will not start again.-
III.Key definitions
Air pump start/stop button:Press to start/stop the air pump,long press to forcefully start the large motor
PSI button:Switch to PSI unit
Bar button:Switch units to Bar
"+"button:Press to increase air pressure incrementally(continuous pressing for rapid increment)
-Key:Air Pressure Decrease:Press to set air pressure decrement(continuous pressing for rapid decrement)
