1. After leveling the instrument, aim at the target F1 in the
collimator with direct telescope, record the current vertical angle
as V0.
2. Set the vertical angle to V0+3′with the help of the vertical
tangent screw. Adjust the screw C to aim at the target precisely.
Press „ENT‟ to confirm after a stable readout appears.
3. Set the vertical angle to V0-3′with the help of the vertical
tangent screw. Adjust the screw C to aim at the target precisely
and press „ENT‟ to confirm after a stable readout appears.
4. Set the vertical angle to V0 with the help of vertical
tangent screw. Adjust the screw C to aim at the target precisely.
5. Aim at the target F2 in the collimator with reverse
telescope and record the current vertical angle as V1.
6. Set the vertical angle to V1-3′with the help of the vertical
tangent screw. Adjust the screw C to aim at the target precisely
and press „ENT‟ to confirm after a stable readout appears.
7. Set the vertical angle to V1+3′with the help of the vertical
tangent screw. Adjust the screw C to aim at the target precisely
and press „ENT‟ to confirm after a stable readout appears.
Tips: Don‟t worry if cannot remember the exact order of
steps. All the above will be displayed on the screen as small
prompts. e.g„F2 Up 3′‟.
The instrument will then calculate out and display the
correction constant and the difference between the compensator
axis and the vertical axis of the instrument. Press „ENT‟ to save
the new calculated parameters, otherwise press „ESC‟ to quit and
the previous correction constant remains.
Notes: Co.k (linear coefficient) must be less than 1.5;
Co.Z (zero position) is normally between -20 and +20,
otherwise the compensator(tilt) must be adjusted mechanically.
9.6.3 Add const&Mul. Const
Operations are permitted only when the instrument was
tested strictly . We recommend you to set it after it is tested by
the factory or professional verification institutions .
