on the target as the collimator directs ,record the current
vertical angle V1; Set the vertical angle as V1-3
′
by slow
motion screw, adjust the angle spiral C to focus on target
accurately , stay for a stable reading , press "confirm" ; Use the
vertical circle slow motion screw to set the vertical angle as
V1+3
′
and adjust the angle spiral C to focus on target
accurately, wait for a stable reading ,press "confirm". All of the
above four steps, there must be tips of "direct telescope updip
3 minute","direct telescope downdip 3 minute", "reverse
telescope updip 3 minute "," reverse telescope downdip 3
minute", the movement is according to the tip. Completing the
above actions, the instrument will work out the correction
coefficient and the deviation between compensating axis and
vertical axis automatically, and shows it, use "ENT" button to
preserve these parameters and exit. The "ESC" key to directly
exit, compensator parameters remain unchanged.
