13. Wait a few seconds for the display to stabilize,
then read the automatically compensated angles
X4 and Y4.
14. In this state, the following offset values (tilt zero
point error) are calculated.
Xoffset = (X3+X4)/2
Yoffset = (Y3+Y4)/2
When both offset values fall within the range ±10",
adjustment is completed.
Press
{ESC} to return to <Instr. const>.
If one of the offset values (Xoffset, Yoffset)
exceeds ±10", repeat the check and adjustment
procedures from the beginning. If the difference
continues to exceed ±10" after repeating the
check 2 or 3 times, have your Sokkia agent
perform the adjustment.
