2 Description of the System
2.1 System Components
The Zone80 DG is a laser tool for general construction, levelling and slope applications such as:
•
Setting forms,
•
Agricultural levelling applications,
•
Levelling to grade,
•
Controlling grade levelling,
•
Controlling depths for excavations.
If set up within the self-levelling range, the Zone80 DG automatically levels to create an accu-
rate horizontal, vertical or sloped plane of laser light.
Once the Zone80 DG has levelled, the head starts rotating and the Zone80 DG is ready for use.
30 seconds after the Zone80 DG has completed the levelling, the H.I.Alert system becomes
active and protects the Zone80 DG against changes in elevation caused by movement of the tri-
pod to ensure accurate work.
The Zone80 DG is a dual grade laser;
it produces an accurate plane of laser
light for applications which require
level (1), single slope (2) or dual slope
(3).
