aligned.
•When the telescope is correctly focused, the cross hairs and the image of the sta must
remain aligned when moving your eye behind the eyepiece.
MEASUREMENT - HEIGHT
•Read o the height of the sta at the centre horizontal line of the
cross hair.
•Height measured in the gure: 0.9 m
MEASUREMENT - DISTANCE
•Centre the measuring tool above the point from which on the
distance is to be measured.
•Read o the height of the sta at the top and bottom stadia lines.
•Multiplied the dierence between top and bottom stadia line by 100,
it’s the distance from the unit to the sta.
•Distance measured in the gure: (0.932-0.87)x100 = 6.2 m
MEASUREMENT - ANGLES
•Point the measuring tool towards the rst point.
•Set the horizontal circle (4) to 0°.

height from sta B (ie. 1.712m).
•Height= A-B= +0.212m showing B is 0.212
higher than A.
•Position the measuring tool 1m away from
sta A.
•Read o height from sta 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.
