For Interior work, we suggest using slower speeds, where the laser beam is
easier to see by eye; but for Exterior Groundworks – run the FRE-301R @ its
maximum speed of 600rpm, which gives the best working range when used
with the supplied Laser Detector. Even with its bright Red beam, a detector
will still be required for most outdoor work.
SCAN function - for Interior setting-out:
The top button on the right of the keypad is the Scan function. The User can
set a Dot, or 10, 45, 90, 180 degree lines as required & use the two buttons
(top left hand side of the keypad) to move these "lines" around the room.
AS THIS LASER AUTO LEVELS BOTH HORIZONTALLY & VERTICALLY,
all the control settings above operate in either mode.
(Vertical leveling,
with the laser positioned on its side, is often referred to as "
Laydown
")
Grading:
This is a
DUAL GRADE
facility laser level. This means that the FRE-301R can
be switched to "Manual" (to over-ride the level sensors) and then the User
can set a grade (incline/slope) in the X axis only, Y axis only or both together.
The max. settable slope is an approx. fall of 1m over 10m.
For X & Y alignment, please see the case markings on the TOP of the laser
body where an arrow points in the direction of the axis being set.
Setting a single axis slope
-
This sets a grade in the X axis.
Procedure – switch ON; the FRE-301R then auto levels. Press the "Manual"
button on laser's keypad (bottom left hand side) & the green LED illuminates.
Using the left & right Arrow buttons, set the % slope (fall) required - as
measured on your staff. The same buttons can be found on the Remote
Control.
To return to Auto level, switch the Manual button to OFF (green LED turns
off). The Laser will wait to find true level, then automatically restart, self-
levelled.
Setting Y axis slope -
This sets a grade in the Y axis.
Procedure – switch ON; the FRE-301R then auto levels. Press the "Manual"
