POSSIBLE ERRORS
If the measurements calculated by the laser are incorrect, this could be
caused by :
• use of the laser near plastic or glass windows.
• dirt or obstruction of the beam windows.
• the laser may have fallen over without your knowledge. This highlights the
importance of regularly checking the laser’s precision.
• extreme changes in temperature, e.g. using the laser in a cold
environment after storing it in a warm environment. Wait a few minutes for
the device to reach room temperature.
