ADJUSTMENT
The user is expected to carry out periodic checks of the instrument's accuracy.
PLATE LEVEL ADJUSTMENT
Secure the instrument onto a suitable tripod and proceed as follows:
· Level the instrument with the circular bubble
· Rotate the instrument until the plate level is parallel to a line between two footscrews
· Use these two footscrews to centre the plate level bubble
· Now rotate the instrument by 90° and centre the bubble once more using the third footscrew
· Repeat the procedure until the bubble is centre in all positions. If not, proceed, as follows:
· Rotate the instrument until the plate level is parallel to a line between two footscrews. Use these
two footscrews to centre the plate level bubble
· Rotate the instrument exactly 180° and note the position of the plate level bubble
· If the bubble is not central the plate level should be adjusted
· Remove half of the deviation with the plate level adjusting screw with the adjusting pin supplied in
the tool kit and half of the deviation with a footscrew
· Repeat the above procedures until the plate level is centred in all positions.
ADJUSTMENT OF CIRCULAR VIAL
With the instrument leveled as indicated in the previous paragraph check if the circular vial is centred. If
not centre it with the adjusting pin supplied in the tool kit.
CENTRING LASER ADJUSTMENT
Fix the instrument on a suitable tripod and power on the centring laser. Rotate the footscrews to centre
the laser beam exactly over a target plate. When the instrument is rotated by 360° the laser beam
should stay centred in all positions. If not, the centring laser should be adjusted.
Adjust as follows:
Unscrew and remove the centring laser cover. Adjust the screws using the adjusting pin supplied in
the tool kit until the laser beam coincides with the center of the target plate. Check by rotating the in-
strument 360° and ensure that the adjusting screws are secure with equal tension. These adjustments
should be carried out by a trained engineer.
