Measurement Result
Measurement result unreliable
Cause: Target surface is not reflecting clearly (e.g. water, glass)
Corrective measure: Cover the target surface
Cause: Laser beam output (13) or reception lens (12) is concealed
Corrective measure: Always keep the laser beam output (13) and the reception lens (12) clear
Measurement result implausible
Cause: Obstacle in the course of the laser beam
Corrective measure: Ensure that the laser point is fully on the target surface
Cause: Incorrect reference level set
Corrective measure: Select the reference level appropriate to the measurement
