Data Record After setting the reference to zero, the last reference value is still maintained when the power is turned on or off.	Super Magnetic Base Attaches firmly to the metal surface. Super suction power to ensure that it won't fall off during the adjustment process.	Battery-Powered Mode This car camber tool is powered by two AAA batteries.The battery is not included, you need to buy it separately.

Easy to Use: Use the camber gauge to determine which tire's camber angle needs to be adjusted; Remove the camber caster gauge and remove the tire; Attach the camber gauge to the brake disc and adjust the positioning bubble to the center; Press the "ON/OFF" button to turn on, after the number on the interface is stable, press the "ZERO" button to reset (the interface displays "0.0" and "ZERO" at the same time); Replace the bolt on the shock absorber of the original car with an eccentric bolt; Adjust the eccentric bolt to make the camber angle reach the expected value, and tighten the eccentric nut with a torque wrench ("Up arrow" means inward tilt, so the value needs to be adjusted down; "Down arrow" means outward tilt, so the value needs to be adjusted up); Install the tire, remeasure with the camber angle, and correct other angles (If there is a slight deviation in re-testing with the camber angle, just fine-tune it under the car. Generally, a slight deviation will not cause positioning faults).
