How to Rotate the Left and Right Disks?
1 Answers
The purpose of rotating the left and right disks is to eliminate parallax and instrument errors. In principle, there is no distinction between left and right. If the included angle is an acute angle and the instrument also displays an acute angle, it is considered the left disk. You can determine the left and right positions based on the horizontal spiral and the battery's location relative to the car owner. If the battery is on the right, it is the left disk, and the level tube bubble will also face the car owner at this time.
