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 controll 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
NL810 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.
Remote control
Features of NL810 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.
Changing the channel in laser level:
• Turn the laser level.
• Hold the X / Y for about 5 seconds. You will see the blinking icons:
antenna and channel number.
• Change the channel number using the + or - on the same as the one set
the remote control.
• Remember, holding the X / Y until turns off the channel number.
• antenna icon continue to blink.
• Then turn off the laser level and turn it on again.
• non-blinking antenna icon indicates a proper connection with the remote
NOTE:
In exceptional cases, you may experience instability working of laser level in cooperation with
the remote control. This is caused by data transmission system between the remote control and
leveling tool. The communication system is based on a radio transmitter operating on UHF. In
this range there are multiple transmission systems and their frequencies can interfere with each
other. In the case of unstable behavior leveling change the channel on the remote control
communicates with the leveling tool.
