Line/scanning mode
By pressing and releasing the scan size button 2, the unit is set to scan mode. Rotation mode is stopped.
The unit starts at an opening angle of 8 degrees. Pressing the button again increases the angle to 45, 90 and 180 degrees.
By pressing and holding the scan size button 2 a programmable scan zone can be created by turning the prism manually from the desired
By pressing the arrow buttons 4 and 5 the scan zone may be moved clockwise or counterclockwise. By pressing and holding the buttons, the movement will be accelerated.
When pressing the buttons on the keypad, the unit may temporarily become out of level due to its high accuracy.
Manual mode/Single Slope mode
By pressing the 'M' button on the remote control or the
By pressing the 'M' button again in horizontal operation, the unit is set into Single Slope mode. This is indicated by the flashing red 7 and green 6 LEDs (once every second). In vertical setup, pressing the 'M' button again switches the unit back to automatic self leveling mode. In Single Slope mode, the
Self-leveling, Height change (HI) alert
Once turned on, the unit automatically levels itself in ranges of 8% (± 0,8 m / 10 m; 8 ft/100ft)). In order to recognize the leveling process at the measuring area and in order not to mark faulty heights during this operation, the rotation stops.
Once leveled, the unit constantly monitors its level condition. The Height change (HI) alert is activated 5 minutes after
Level errors > 30 mm/10 m
LEVELING ACCURACY
Influences on the leveling accuracy
The overall accuracy of the unit can be influenced by many factors:
•factory accuracy;
•temperature of the unit;
•ambient influences like rain, wind and temperature.
The factor which influences on the unit's accuracy most is the ambient temperature. Vertical differences in temperature near the ground can divert the laser beam, similar to the heat waves seen on hot asphalt streets.
This factor also applies to all optical measuring devices such as automatic levels and theodolites.
