Switching on and measuring
!
Make sure that the reference function is deactivated before
measuring.
The DigiLevel Laser G40 / G80 can measure angles continuously to 360°.
– Switch the DigiLevel Plus on using the on/off switch (4).
– The slope angle is shown in the display (8). If slopes are measured
overhead, the direction of display adjusts automatically.
– The current slope direction is also shown by the symbol (7).
3 Selection of unit of measurement
Button (5) allows the desired unit of measurement to be selected
(° degrees, %, mm/m).

Calibration
1. Place the unit with its measuring edge (18) down on a straight
surface and mark the positions of the unit's ends on the under-
lying surface (see Fig. below). Switch the unit on (4) and press
the REF button (2) until CAL 1 starts blinking. Shortly thereafter
an acoustic signal will sound and CAL 2 will appear in the display.
2. Now turn the unit around horizontally (end-for-end) by 180°
such that its ends are positioned opposite where they previously
were but again exactly at the underlying surface marks (reverse
measurement). Again press the REF button (2) until CAL 2 blinks.
The subsequent acoustic signal concludes the process.
!
The unit is properly calibrated when it displays the same
measurement value, i.e. the underlying surface's deviation
from absolute level, in both positions (0° and 180°).
