Accuracy Adjustment
•
It is the responsibility of the user to follow operating instructions and to periodically check
the accuracy of the laser and work as it progresses.
•
The Zone60 DG is adjusted to the defined accuracy specification at the factory. It is recom-
mended to check the laser for accuracy upon receipt and periodically thereafter to ensure
accuracy is maintained. If the laser requires adjustment, contact your nearest authorised
service centre or adjust the laser using the procedures described in this chapter.
•
Only enter the accuracy adjustment mode when you plan to change the accuracy. Accuracy
adjustments should only be performed by a qualified individual that understands basic
adjustment principles.
•
It is recommended to perform this procedure with two people on a relatively flat surface.

hecking the Level Accuracy
☞
The Zone60 DG is within its accuracy specification if the four marks are within
± 1.5 mm (± 1/16") from the centre.
1.
Place the Zone60 DG on a flat, level sur-
face or tripod approximately 30 m
(100 ft) from a wall.

2.
Align the first axis so that it is square to a wall. Allow the Zone60 DG to self-level
completely (approximately 1 minute after the Zone60 DG begins to rotate).
3.
Mark the position of the beam.
4.
Rotate the laser 180° and allow it to
self-level.
5.
Mark the opposite side of the first axis.
6.
Align the second axis of the Zone60 DG
by rotating it 90° so that this axis is
square to the wall. Allow the Zone60 DG
to self-level completely.
