Technical hints for measurements
Special measuring situations
Vibrations
Vibrations at the instrument, e.g. due to wind can be
damped by touching the upper third of the tripod.
Back light
Use the lense hood (optional accessory) to cover
the objective when back light disturbs your work. As
a last resort, use your hands to shield the objective
from disturbing backlight.
Darkness
Evenly illuminate the measuring area of the staff
with a flashlight or spotlight in darkness.
Measuring at the beginning of the staff
Measurements slightly below the zero point are
possible (negative measured values).
Measuring at the upper end of the staff
With the following staffs, measurements can be
made up to the end of the staff: 4.05m; 2.95m;
2.70m; 1.95m und 1.82m.
With other staff lenghts, measurements up to the
upper ends are not possible.
Code length required in the field of view
For exact measurements, the centering
area in the field of view should be free of
any interfering cover.
The following code lengths are required in the field
of view, depending on the distance, from which the
permitted amount of interfering cover on the edges
of the field of view can be determined:
