1.2 AIM AND FOCUS 1. Remove the objective lens cover (7), direct the telescope towards a bright object or hold a white sheet of paper in front of the objective lens (7) then, turn the lens (13) until a black crosshair can be seen clearly. 2.
MEASURING FUNCTIONS 2.1 MEASURING HEIGHT 1. Place the instrument between two measuring points: A & B (see fig.2). 2. Position the measuring rod on point A, focus the telescope to the center of the rod and record the height value at the center of the crosshair (see fig.3). figure #2 Measuring rod Measuring rod...

2.3 MEASURING ANGLES 1. Aim the telescope towards point A, rotate the horizontal scale (2) so that the zero points towards the reference mark (3) (see fig.7). 2. Aim the telescope towards point B, read off the angle value on the scale (2) at the reference mark (3) (see fig.7). Horizontal scale Horizontal scale Reference mark...
TESTING AND TUNING Before using this instrument or after a long transportation, the leveling and indication accuracy should be tested. 3.1 TESTING THE CIRCULAR BUBBLE VIAL 1. Adjust the telescope with the leveling screw knob (9) so that the air bubble is in the center of the circular vial (10). 2.
TESTING ANGLES 1. The testing must be conducted at a distance of 30m. Place the telescope in the center between the two measuring points: A & B (see fig.10) 2. Read the heights of the two measuring rods and calculate the difference (d) between a1 and b1.

b2'=a2-d figure #11 3.3 ADJUSTING THE CROSSHAIR 1. Remove the lens cover. (12) 2. Using the adjusting pin, turn adjusting screw clockwise or counterclockwise until the height value of b2 and b2' on measuring rod B, are the same. 3. Return the lens cover on the lens.
MAINTENANCE AND SERVICE Careful use and maintenance of the instrument can guarantee its accuracy and efficiency. 1. After measuring, wipe clean all the surfaces of the instrument and put into the carrying case. 2. Dust off all optical parts with a soft brush and clean the lens with lens tissue.
