1 – Accuracy of correction will depend on accuracy of
installation against target. If distance is 0.9 meters, then
unit will have 0.1 m offset during all future
measurements.
2 – Target should not have high-reflective surface (white
color is not considered high reflective in this case.
3 – Unit shall be well levelled with deviation from 0 not
more than ±0.75 degrees. Horizontal direction shall be to
Magnetic North (not True North). If devices detects large
installation errors (unit is not well levelled or not aimed to
the North), then LCD will show result “444” and “99”,
which means that correction was not performed due to
incorrect setup.
