7. APPLIED OPERATIONON
It is possible to set grades for the laser beam and various functions from the menu screen.
• It may take some time for the laser to be emitted after the rotary head rotates, but this is not a malfunction of
the instrument.
There are two methods to set grades on the laser beam: 1) direct entry of the grade values for the X axis (1S)
/ X and Y axes (2S), and 2) matching to set grades on laser beam according to the slope of the ground on site.
Grade can be set in both axes, X and Y (2S)/ in the X axis (1S), as shown below.
Grades can be set in the range indicated below.
Grade axes and axis symbols are as shown in the diagram below.
On the tripod whose head is horizontally placed, grades will automatically level to approximately ±8%. When
setting larger grades, tilt the RL-HV towards the direction of the slope to maintain within the self-leveling range.
When exceeding the self-leveling range, the error message "Exceeding leveling range" will be displayed.
• If you set grades by placing the RL-HV 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 self-leveling,
laser will emit.
