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
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.
