2. Basic Operation 2.1 Standard Set-up Levelling (see dia over page) Place unit on tripod and roughly set up so that the instrument is within 5% of level. Switch the unit on (d). The unit will then level itself and the diode will emit a beam and commence spinning.
Page 7 The receiver has two settings; a course and a fine setting. The band width and the audio volume can be adjusted using the receiver’s buttons. Standard Leveling Set-up When set up the instrument will create a laser beam across the entire work site to a radius of 250m and the receiver will give a signal in all points within the instruments range...

3. Grade Slope Operation The Imex 99DG has a semi-automatic grade slope function to 10% on both X and Y axis’s. This allows for the following tasks to be performed; Sloped concrete slabs, drainage slope, ceiling and grid slopes, fencing slopes.
Page 9 3. Grade Slope Operation cont: 3.3 Dual Grade Sloping – Used for areas where a fall is made simultaneously to a point 90º to the other axis. Ideally site instrument to one corner of the worksite. Set X axis as shown. At 90º to the X axis set the Y axis in the same manner.

4. Scan Mode Operation The scan mode function allows the laser beam to emit only in a restricted radius. This function is useful for; - Internal layout work where work is being carried out in single runs or sections i.e. wall or ceilings - On restricted sites internal or external where other laser or electrical equipment may be in use - On busy sites where eye safety with other workers may be an OH &...
Page 11 5. Vertical Function The vertical function allows the instrument to be laid horizontally and a vertical line is emitted. This function is used for; - Alignment of formwork or pipeline runs in external situations - Alignment of internal wall, floor and ceiling layout - In conjunction with the plumb spot beam, which is always 90º...
