Setting Grades
(requires remote control that comes with Grade & Grade +MM kits)

OPERATING INSTRUCTIONS cont.
The EL614 Grade and Grade + MM kits come with a remote control that
can set a grade on one axis, it can be set to either the “X” or “Y” axis but
not both.
First set up the laser aligning the X axis with the direction of the required
grade rise/fall, the laser can be placed anywhere on site as long as the X
axis runs parallel or in line with the desired grade.
For this example we want a grade of 1 in 60 or 1.667% or in other words
for every 6m (6000mm) travelled away from the laser along the X axis we
want the laser plain to tilt down/up 0.1m (100mm).
To achieve this measure out 6m away from the laser along the X axis and
hold the staff at this point slide the receiver up/down the staff until the
receiver indicates level.
Then making a note of the height on the staff slide the receiver up/down
the staff 100mm from the level point, this is now the height the laser needs
to be hitting to be setting a 1 in 60 slope or grade.
Using the remote, select grade mode on the X axis and use the Slope Grade
Direction buttons to slope the laser until the receiver shows level (see page
6 for remote diagram).
The Grade is now set at 1 in 60 or 1.667% on the X axis and anywhere on
or parallel to the X axis on site.
