VEVOR Tire Inflator Portable Air Compressor, 150 PSI Electric Air Pump, 4000mAh Rechargeable Tire Pump with Auto-Off Function, LCD Pressure Gauge, 3 Nozzles, LED Light for Car Motorcycle Bike Ball
Hi, how can I calibrate the pressure readings? When I connect the inflator to a tyre it reads 1.00 Bar, but when I measure it using two different pressure gauges I see the tyre inflated to 1.40 Bar.
Can I put the unit into a calibration mode and set the pressure?
Thanks.
Dear Customer, Thanks for your inquiry.
After power on, do not connect the trachea, press the + - button for 3 seconds at the same time, release it after the display screen is fully lit, and wait for the calibration to complete.
