7. APPLIED OPERATION AND SETTING OF VARIOUS FUNCTIONS
It is possible to set grades for the laser beam and various functions from the menu screen.

7.1 Setting Grades

There are two methods to set grades on the laser beam: 1) direct entry of the grade values for
the X and Y axes, and 2) matching to set grades on laser beam according to the slope of the
ground on site.

„ How to enter grade values

Grade can be set in both axes, X and Y, as shown below.
Grades can be set in the range indicated below.

Single axis Dual axes

X axis Y axis

Grade range:
Grade range:
X: –15% to +15%
X: –15% to +15%
or
Y: –15% to +15%
Y: –15% to +15%

Y axis X axis
Minus Plus Plus Minus

Plus Minus Minus Plus

-15% +15%

Panel side
On the tripod whose head is horizontally placed, grades will automatically level to approximately
±8%. When setting larger grades, tilt the RL-SV2S towards the direction of the slope to maintain
within the auto leveling range. When exceeding the auto leveling range, the error message
"Exceeding leveling range" will be displayed.C12. ERROR DISPLAY(p. 65)

G
If you set grades by placing the RL-SV2S in a place where temperature suddenly changes, let
the instrument stand for about 10 minutes to allow it to adjust to the temperature prior to actual
use.
When temperature changes 5°C or more after setting a grade,
temperature difference is detected and the grade is corrected
automatically. During auto correction, laser will stop temporarily
(and [AUTO CALIb] will be displayed). When auto correction is
completed, the display will return to the grade setting, and after auto
leveling, laser will emit.
