7. APPLIED OPERATION AND SETTING OF VARIOUS FUNCTIONS
Grade axis and axis signs are as shown in the diagram below.
On the tripod whose head is horizontally placed, grade will automatically level to approximately
±8%. When setting larger grade, tilt the RL-SV1S 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.12. ERROR DISPLAY(p. 66)
• If you set grade by placing the RL-SV1S 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
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.
