HORIZONTAL FINE ADJUSTMENT BRACKET
With the horizontal fine adjustment bracket the
instrument can be adjusted precisely on the tripod.
Loosen screw 13 and make a coarse adjustment
of the plate by hand. Then set the instrument
exactly using screws 14. Fix screw 13 again when
the fine adjustment is completed.

ACCURACY CHECK

The user is expected to carry out periodic checks of the product's accuracy and general performance.
1) Mount the instrument on a tripod and set it up 20 m apart from a wall - the X axis showing to the wall.
2) Switch on the instrument and let the laser complete its self-levelling procedure.
3) Mark a laser beam on the wall with point „A".
4) Turn the instrument in 90° steps and mark the points „B", „C" and „D" accordlingly.
5) Measure the distance „h" between the highest and lowest point from „A", „B", „C" and „D".
6) If „h" < 2 mm, the accuracy is okay. If the difference is beyond please have the instrument adjusted.
DUAL GRADE APPLICATION
Note
It is recommended to use two receivers.
Laser
Step 1: Let the laser complete its self-levelling procedure.
Step 2: Set the value of the axis with longest distance. I.e.: X = 1 % / 50 m, therefore in 50 m = 50 cm.
Now set the value of the Y axis. I.e.: Y = 3 % / 20 m, therefore in 20 m = 60 cm.
