Red laser to prisms
Accurate measurements to prisms should
be made with the standard program (Reflector EDM
mode).
Red laser to reflector tape
The visible red laser beam can be used to measure
to reflective foils, also. To guarantee the accuracy
the red laser beam must be perpendicular to the
reflector tape and it must be well adjusted (refer to
the chapter "Checking and adjusting").
Make sure the additive constant belongs to
the selected target (reflector).
