OPERATION INSTRUCTION

SET UP - MOUNTING ON TRIPOD

•Set up your tripod as levelled and stable as possible.

•Securely place the measuring tool on the tripod via the 5/8”thread.

SET UP - ALIGN THE TOOL

focusing knob (9) until the cross hairs appear clear and sharp.

•Point the measuring tool towards the sta through the peep sight (2). Continue to adjust

the focusing knob until the the graduation eld of the sta appears clear.

•Adjust the horizontal drive screws (10) until the vertical hair and the centre of the sta is

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°.

•Direct the measuring tool towards the 2nd point.

•Read o the angle at the reference mark.

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 o height from sta A (ie. 1.924m).

Turn the measuring tool and read o

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.

MAINTENANCE AND SERVICE
