Set the instrument up with clear sights of abort 50 to 60 meters of both sides of the instrument. - Page 33 Electronic Theodolite User Guide Adjustment a. Unscrew the cross-hair adjustment section cover. b. Find point D at a point between points C. B, which should be equal to 1/4 the distance between points B and C, and measured from point C. This is because the parent error of BC is four times of the real error since the telescope has been reversed twice during checking operation.
