OPERATION
Horizontal and vertical leveling
Open the battery compartment and insert the batteries according to the
polarity. Don’t confuse the polarities.
Press button . A vertical and horizontal laser lines appears.
While working in the switched-on self-levelling mode, when the instrument
is put on a rough surface or on a tripod with a tilt more than 4,5° laser
lines start to blink, signalizing that the instrument is out of the automatic
selflevelling area.
In this case it is necessary to put the instrument on a flat surface.
Preparing the calibration check
It is possible for you to check the calibration of the laser. To do this, position
the device midway between 2 walls, which must be at least 5 meters apart.
Do this by turning the unit on. See Section «Horizontal and vertical leveling»
about this.
1. Mark point A1 on the wall.
2. Turn the device through 180° and mark point A2. You now have a
horizontal reference between points A1 and A2.
Performing the calibration check
3. Position the device as near as possible to the wall at the height of point A1.
4. Turn the device through 180° and mark point A3. The difference between
points A1 and A3 is the tolerance.
When A1 and A3 are more than 4 mm/10 m apart, an adjustment is necessary.
Contact your authorised dealer or else CONDTROL Service Department.
Checking the vertical line
Position the device about 5 m from a wall. Fix a plumb bob with a line of 2.5 m
length on the wall, making sure that the bob can swing freely. Switch on the
device and align the vertical laser to the plumb line. The precision is within
the specified tolerance if the deviation between the laser line and the plumb
line is not greater than ± 1.5 mm.
Checking the horizontal line
Position the device about 5 m from a wall and switch on the cross laser. Mark
point B on the wall. Turn the laser cross approx. 2.5 m to the right and mark
point C. Check whether the horizontal line from point C is level with point B to
within ± 2 mm. Repeat the process by turning the laser to the left.
