1.3 Standard Function
The instrument is equipped with a semi-conductor diode with
wavelength of 635nm. The laser beam is clearly visible, and the laser
module rotates freely to form a laser scanning surface.
In the upright position, ideally placed on a standard aluminium tripod
the laser beam emits a horizontal line which can be detected by the
instruments receiver.
On the 99DG, if the unit is placed in a horizontal position, the laser
emits a vertical beam.
A plumb spot at 90º to the main beam is emitted from the base and
the top of the instrument.
Horizontal operation Vertical Operation
A remote control is provided which works on an infra-red system up to
20m-30m from the instrument. The control panel has the same
functions as the control panel on the instrument itself.
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. The instrument will commence spinning at its
maximum speed of 600rpm.
If the unit is bumped or moved the laser will stop and the out of level
warning symbol will flash. After the instrument has re-levelled itself the
laser will recommence spinning.
- Warning –If the unit has been bumped or moved and the unit
recommences spinning, the instrument may not automatically be at the
original level. Re-check on a datum point.
2.2 Hi-Alert Mode: Using the Hi alert mode, button (i), if the laser is
bumped or moved it will not re-level & recommence spinning until you
press button (i) again, therefore you can be assured accuracy
2.2 Rotation Speed: If a slower speed is required, i.e. for better
visibility; press the speed control button (h).
Speed will revert to 0rpm, press button again to get required speed.
2.3 Receiver Set-up: Using the bracket included, mount this onto a
staff or grade rod.
Turn the receiver on and raise or lower the receiver on staff until it makes
a continuous beeping sound. This is the point level of with the
instrument.
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.
3.1 Grade Mode
For best results use the remote control. Set up the instrument in the
direction of slope required.
Turn on grade mode using button (a).
Once grade mode is activated ‘X’ will flash on the grade display (e) and
grade slope indication (l) will turn on
By holding down grade setting buttons (f) or (g) you can now enter your
desired slope on the x axis
To set grade on the y axis press button (b) x/y selection button, then the ‘Y’
indicator on the display screen will flash
Again using the grade setting buttons (f) & (g) you can now enter your
desired slope on the y axis
Once you have set you required grade slopes on the x & y axis, press x/y
selection button (b) so both the ‘X’ & ‘Y’ indicator on the display screen
remain on
The laser will continue to spin for 30 seconds and will then bring the x & y
values on the display screen back to 0.00%
The laser will then start to adjust to your set grade slope
Once your set slope is reached, this will be displayed on screen. i.e. X
2.50% Y-5.69%
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. The grade is now set for both runs.
X axis
Direction of slope
Y axis Direction of slope
3.3 Exiting Grade mode
To exit grade mode press and hold button (a) grade display setting (e) will
disappear and unit will re-level itself into level position.
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 & S issue
-On single long external runs i.e. pipe laying where full 360º is not required
-Especially useful in vertical mode 180º operation
4.1 Operating the Scan
With the unit on, press the scan button (h). Set the width required 0º, 10º,
45º, 90º or 180º by pressing the button once for every scan width
increment.
To change the direction or position of the scan use the scan direction
buttons (f and g). Press either of these buttons until the desired position is
reached.
