3. To precisely level the instrument up, make the plate level parallel to the connecting
line of two foot screws, and turn the third foot screw.
4. To power on the instrument, press for 3 seconds, and make sure the
compensator is turned on (Character shows).
5. Aim the telescope at the reticle center on the face left, and write down the vertical
angle VI.
6. Adjust the third foot screw, make the instrument tilt 3' (6 lattices set in the reticle)
upwards, turn the vertical tangent screw, collimate the target again, and write down
the vertical angle VI1.
7. Adjust the third foot screw, make the instrument tilt 3' (12 lattices set in the reticle)
downwards, turn the vertical tangent screw, collimate the target again, and write down
the vertical angle VI2.
8. Calculate the value of |VI1-VI| and |VI2-VI|, and check if the results are less than 5':
o
If they are, no adjustment is required.
o
If not, proceed to step 9 .
9. To enter the factory setting, power off the instrument, press , V/% and R/L at the
same time, release , and release V/% and R/L at the same time when character
FAC shows. The character SETP1 flashes on the second line on the display.
10. Adjust the third foot screw to aim the target, write down the vertical angle VI1, and
press OSET . The character SETP2 flashes on the second line on the display.
11. Adjust the vertical tangent screw, and make the vertical angle plus 3'.
12. Adjust the third foot screw to aim the target, write down the vertical angle VI2, and
press 0SET . The character SETP3 flashes on the second line on the display.
13. Adjust the vertical tangent screw, and make the vertical angle minus 6'.
14. Adjust the third foot screw to aim the target, write down the vertical angle VI3, and
press 0SET .
15. Mare the maximum among VI1, VI2 and VI3 as VImax and the minimum as VImin.
16. Calculate the value of |VImax-VImin|, and check if the result is less than 6''.
o
If it is, adjustment finishes.
o
If not, repeat step 9 - 16 .
