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.
Slope determination
Set the laser level on a tripod. Set the laser level in the axis you want to tilt and
turn on the laser level. The laser plummet (bottom) indicates the first point of the
axis, on the other end point set the laser staff with laser sensor - reset position
(sensor and staff). Depending on the desired value of inclination slide the
sensor on a staff and by remote control change the inclination of the laser plane
in order to fit in the position of the laser sensor (this shift of laser sensor will
specify the inclination, eg. If you want to get a inclination of 1%, at a distance of
10 m (laser staff) the difference between the height of the zero point on the staff
should and designated inclination should be 10 cm).
Working with the vertical plane
NL610/ NL610G can set horizontal or vertical beam. If you work with a vertical laser beam
you must set the laser level as in the picture beside. After switching on the laser level the
device will level by itself
– the head will start to rotate - setting a vertical plane.
The laser plummet (top) defines a line perpendicular to the plane of the laser level, which
is used in all perpendicular works (building partitions, setting 90
° angle, etc.).
Remote control
Features of NL610/610G laser level can be controlled remotely using the remote control. On the
remote control panel there are buttons that correspond to those included on the front panel of
laser level. The operating range of remote control is approximately 20 meters (depends on the
conditions on the site)
The procedure for changing the transmission channel.
Changing the channel must be carried out separately on the remote control and laser level.
Changing the channel on the remote control:
• Turn the remote by on/off switch by holding it so long until you see the blinking icon
similar to the phone and will be displayed next to the channel number.
• Change the channel number by pr or -.
• Confirm by holding down the power button on remote control.
