Tripod Base
(refer to diagram page 4)
The CXR880
TM
can be operated with or without the Tripod base. The base is
ideal for outdoor squaring/layout as the Fine Adjustment Rotation knob (c)
is handy for aligning the vertical beams, also indoors it is particularly useful
when using the laser for plumb alignment. The Adjustable Feet (e) can be
used to bring the laser into self levelling range with the aid of the Bubble
Vial (b) when the laser with base is placed on the ground. To remove the
base place the Lock Switch (d) in the locked position and rotate the base off
anti-clockwise.
Setting a Site Square and layout
The CXR880
TM
has 4 vertical line all at 90 degrees to each other, this makes
this laser ideal for setting Site Squares and general outdoor and indoor layout
without the need to do a 3-4-5 calculation.
First place the CXR880
TM
over the datum corner for the desired 90 degree
square using the plumb down reference point. Next align one of the vertical
lines with one of the lengths by placing the receiver on it side at the far end
of the line to the datum point. (remember turn on in line mode and select
relevant range sensitivity see page 12)
Turn on all vertical lines, turn tilt off and select pulse mode (outdoor mode),
rotate the body of the laser at first manually then with the fine rotation
knob until the receiver picks up the laser and the solid tone indicating level
is heard. (sometimes its hard to get the laser beam exactly on the level
solid tone due to the extreme accuracy of the receiver if you get within a
millimetre or so that will be accurate enough for most jobs)
Take the receiver over to 90 degree line move the receiver side to side slowly
until you pick up the line and again get the solid tone. The point from the
receiver to the datum point is the second length of the square and is at 90
degrees to the first, your site square is done.
