Adjusting the laser output
This is the value which the laser power adjustment control was on during
automatic
operation mode.
To manually adjust this value, aim the scanner to the surface to be scanned. Continue by
reading the value of the laser output control. Now switch the laser adjustment control to
manual
operation mode (see section 8 for how to change values) and write this value
(Output of the adjustment control * 4) into the register “Exposure Control”. The laser
output adjustment control is now adjusted on the object to be measured.
