23. CHECKS AND ADJUSTMENTS
9. Confirm that the values are in the adjustment
range.
If both correction constants are within the
range 1600 ±120, select [YES] to renew the
correction angle. <Instrument configurations>
is restored. Continue to step 11.
If the values exceed the adjustment range,
select [NO] to cancel the adjustment and
restore <Instrument configurations>. Contact
your Sokkia agent to perform the adjustment.
PROCEDURE Recheck
10. Select "Tilt offset".
11. Wait a few seconds for the display to stabilize,
then read the automatically compensated angles
X3 and Y3.
12. Press [OK] to automatically rotate the top of the
instrument and telescope through 180°.
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.
