• Support the staff so that it is perpendicular, checking the circular
bubble scope on the staff. If the staff is tilting, height and distance
measurements will be incorrect.
• If the surface is catching the light, turn it just enough to stop the
reflection.
• Make sure shadows are not cast on the staff as this could make
measurement impossible.
• When holding the staff during measurement, make sure your
hand does not cover the RAB code.
• If dark locations make measurement difficult, shine a flashlight on
the staff. Stand at a distance so that the beam shines evenly
