2.3 Vertical Accuracy Verification/Calibration
1.
Set the instrument on the platform and face telescope to the wall.
2.
Tighten the center screw and level the instrument.
3.
Loosen the vertical lock knob and adjust the telescope as shown in
the figure to the right.
4.
Adjust the focus knob until the target on the top end of the wall
could be observed clearly.
5.
Turn the telescope to make the vertical hair of the cross hair
coincide with the zero position of the target.
6.
Adjust the telescope, as shown in figure to the right. To focus
until the target on the lowest end could be observed clearly.
7.
Then observe the deviation D of the vertical hair from the zero
position. If D > 1.5mm, the vertical accuracy of the
instrument is beyond the tolerance and should be calibrated.
2.3.3 Vertical accuracy calibration
1.
If the vertical hair locates on the left side of the zero position, as shown below, use a hexagon spanner to loosen
elevation-difference level screw 2 and tighten elevation-difference level screw 1, as shown below. Tighten the two level
screws simultaneously until the vertical hair coincides with the zero position.
2.
If the vertical hair locates on the right side of the zero position, as shown below, use a hexagon spanner to loosen
elevation-difference level screw 1 and tighten elevation-difference level screw 2, as shown below. Tighten the two level
screws simultaneously until the vertical hair coincides with the zero position.

After the vertical accuracy of the instrument has been adjusted, please recheck the sightline
levelness of the instrument with the same method as above. If the sightline levelness is
beyond tolerance, it is necessary to make readjustment.
