4. With +5.000% in the X-axis, take a second reading at Point A.
5. Alignment:
•
If the second reading is equal to the first reading, the X-axis is aligned cor-
rectly.
•
If the second reading is greater than the first reading, rotate the Zone60 DG
clockwise (to the right) until the two readings are equal.
•
If the second reading is less than the first reading, rotate the Zone60 DG
counter-clockwise (to the left) until the two readings are equal.
☞
An optional sighting scope is available for the Zone60 DG which improves the axis
alignment for second day setups. It is recommended that you first perform the pre-
cise alignment procedure, and then adjust the scope to these axes.
3.9 Laydown Operation
You can use the Zone60 DG in laying down position to create a vertical plane for layout and
alignment jobs.
