ACCURACY CHECK
CHECKING THE CIRCULAR BUBBLE LEVEL
•
Adjust the levellings screws (5) so that the air bubble is centred.
•
Rotate the measuring tool 180°. If the air bubble is no longer in the centre of the bubble
vial, the bubble level must be re-adjusted.
•
Adjust the levelling screws until the air bubble stays at the centre when the tool is turned
to any directions.
CHECKING HORIZONTAL LINE OF SIGHT
•
Set up the measuring tool on a
tripod halfway between two staves
approximately 30m apart and ensure the
tool is levelled.
•
Read off height from staff A (ie. 1.924m).
Turn the measuring tool and read off
height from staff B (ie. 1.712m).
•
Height= A-B= +0.212m showing B is 0.212
higher than A.
•
Position the measuring tool 1m away from
staff A.
•
Read off height from staff A (ie. 1.696m).
Since B is 0.212 higher than A. If reading
to B is1.484m ±3mm, the line of sight is
horizontal.
•
If the readiing is beyond tolerance, cross
hairs must be re-adjusted.
