6 Instrument Technology
Although the problem is reduced with a beam that uses a smaller measuring area, the error can not be
completely eliminated. The most accurate solution to measure to tight corners and eliminate errors
caused by beam divergence, is to use an offset measurement method such as that used in the field
application software.
Do the following:
1. Measure two points on the face of the building.
2. Aim the instrument at the corner to store the correct horizontal and vertical angle.
Offset measurement:
With offset measurements, you can accurately measure difficult locations in reflectorless mode and
eliminate beam divergence errors. For more information, refer to the field application software
documentation.
