Principle Of Operation - Nivel System NL200 Manual

ADS System
Enable this system will cause the LED will blink slowly. After automatic leveling of the
instrument, after about 3 seconds, the ADS function is activated. Excessive inclination of the
instrument or unwanted movement / strike will cause the LED will blink quickly - warning the
user about disheveling.

PRINCIPLE OF OPERATION

Height Measurement
Turn the power on to Level the instrument itself. Once leveled, the laser head starts to spin,
setting the laser plane. Attach the laser sensor on the laser staff. Place a laser staff with
attached sensor on a benchmark (zero point) - reset the position of sensor (adjust the height of
the sensor to define a zero level, the laser staff should also indicate zero). Move the laser staff
with sensor to another point which height you want to measure, adjust the height of the sensor
to place it in the field of the laser beam - move it up or down on the laser staff. The difference of
sensor positions on the staff will indicate the height differences of the measured point compared
to the benchmark.
Checking the laser level
You should regularly check the following parameters of the laser level

setting a horizontal plane

cone error
Checking and calibration of the horizontal planes is simple and in most cases can be done by
the user. Checking the cone error can be also done by the user, but this error can be only
removed by an authorized service center.
1. Set the instrument about 30m from the wall so that the X-axis is perpendicular to the
wall and Y direction a pointed to a wall.
2. Turn on the instrument and wait until it level automatically.
3. Place a sheet of paper on the wall. Mark the position of the laser beam (Ma) on the
sheet. Turn off the instrument.
4. Loosen the tripod fixing screw and rotate the instrument 180 °.
WARNING! Be careful not to move the instrument while the head is spinning.
5. Turn on the instrument once again and wait until it level automatically.
6. Once again mark the position of the laser beam on the sheet (Mb).
7. Measure the distance between the marks Ma and Mb, if the distance is less than 6
mm calibration is not necessary, in other case please contact service center
8. Do same for Y axe
Checking the cone error
Please do this procedure after calibration of horizontal plane.
1. Set the laser centered between the walls distanced from each other of 30 m. Set the
instrument in the X or Y direction.
