We will solve one of the most frequently asked after-sales problems - Laser Level Accuracy Check.
This time we gonna move to Vertical Laser Beams Accuracy Check.
Generally applicable to 3D laser level either.
After ensuring the above conditions, we will start testing now.
Before we start, please take notice that important things:
The accuracy check need to turn on the Self-leveling Mode.
The accuracy check will be affected in the vibration environment.
Before start, we have to say , Vertical Check is relatively complicated.
Place the laser tool on the floor and turn on the vertical beams of the front laser window and side laser window.
Mark the cross point below the laser tool as mark A and remain the laser tool in the same position. mark B on the floor 5m away from mark A, mark the cross point on the ceiling as mark C.
Mark the laser line at the position of mark C on the ceiling as mark D.
Measure the offset of mark C and mark D on the ceiling.
If the measured value is more than the value in the table below, the laser tool should be returned to the service center for repair.
