Nitrogen Tyre Inflator
Model: PN-8820
5.0 The Pressure Calibration Procedures
To the automatic tyre nitrogen inflators, when the users found the inflator accuracy is
higher than 1.5PSI / 0.1bar / 0.01Mpa / 0.1Kgf/cm2, they can calibrate the unit by the
following methods.
1. Open the tyre nitrogen inflator,the below part is seeing on the top of the machine.
2. Turn off the power, take off the accessory (C) from the kick 4 and kick 5 of the
accessory (B), then insert it to the kick 1 and kick 2 of accessory (A).Turn on the
power.
3. Find a 14 inch tyre with the pressure inflated to 2.5bar/36PSI exactly,connect the
tyre to the Automatic nitrogen inflation outlet (refer to Section 2.0 Cntrol Layout)
located in the nitrogen inflator by the Hose with single clip-on open type chuck
inclouded (the customer also should use this hose to inflate tyres,or else will cause
measuring difference.)
4. Currently,the tyre nitrogen inflator LED (PRESSURE SETTING) will display the
pressure reading value,maybe 2.3 bar,2.4 bar,2.5 bar,2.6 bar or other values.Rotate the
knob on the accessory (D) with screwdriver, the reading on the LED will
changing,and adjust the LED display pressure into 2.4 bar/35PSI.
5. Deflate the tyre totally,and the tyre pressure should be 0 bar at this moment,then
connect the tyre to the the Automatic nitrogen inflation outlet (refer to Section 2.0
Cntrol Layout) located in the nitrogen tire inflator (or disconnect the tyre from the
nitrogen tire inflator,and let the Automatic nitrogen inflation outlet located in the
nitrogen tire inflator linked to the atmosphere.)
6. Now the LED will display 0.01 bar,0.02 bar,0.03 bar or any other digitals,then
rotate the knob on the accessory (E) with screwdriver.The reading on the LED will
change too,and adjust the LED display pressure into 0.01 bar.
