How to Calibrate Laser Level?
The best laser level should meet the following conditions
The level axis of the vial should be parallel to the collimation axis of the telescope's collimator. (Main condition)
The collimation axis of the telescope does not change position due to focusing. (Main condition)
The circular level axis should be parallel to the rotation axis of the rotary laser level. (Minor condition)
The horizontal wire of the crosshair should be perpendicular to the rotation axis of the laser level. (Secondary condition)
Inspection before calibration
The principle of inspection and calibration sequence: The previous inspection items are not affected by the following inspection items.
Inspection method: The leveling axis of the level should be tested and calibrated equally with the rotating axis.
