you will cause increase the range of "drawn" line. Depending on your needs, switch the direction
of rotation of the head (clockwise or counter-clockwise).
The inclination of laser plane
NL400 allows you to incline the laser plane in one or two directions
Press to set instrument in manual mode.
To set the incline in X axis press - each time you press the buttons the laser plane
will incline in the X axis
To set the incline in X axis press - each time you press the buttons the laser plane
will incline in the X axis.
TILT function
Enable this system will cause the LED will blink slowly. After automatic levelling of the
instrument, after about 3 seconds, the TILT function is activated. Excessive inclination of the
instrument or unwanted movement / strike will cause the LED will blink quickly - warning the
user about disleveling. Function is working only with automatic mode (it doesn’t work with
manual mode).
WIND function (function is activated automatically)
The equipment automatically adjusts the level of the displayed beam in real time to the field
conditions. When the position of the instrument changes during work, it will be subjected to
vibrations (machines work in the area / strong wind) - the compensator corrects the
inconvenience and leveling the beam display at all times (without switching off the equipment),
ensures continuity of work in extreme conditions on the construction site. The function does not
work in manual mode.
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
