SHANGHAI ESURVEY GNSS CO., LTD. 6. Turn the eyepiece end until the vertical line of the reticle overlaps with point A: 7. Tighten the four screws fixing the reticle. 8. Repeat calibration until point A always moves along the vertical line of the reticle. After doing correction for the vertical line of the telescope reticle, check the collimation error and index error of the instrument.
SHANGHAI ESURVEY GNSS CO., LTD. Horizontal axis: the measured temperature. Vertical axis: the pressure. Diagonal line: the required atmospheric correction value. 8.2 Correction for Refraction and Earth Curvature Considering the correction of refraction and earth curvature for distance measurement, the formula for slope distance, horizontal distance and vertical distance applied in the instrument are as followings: ...
SHANGHAI ESURVEY GNSS CO., LTD. The conversion formula for horizontal and vertical distance is as follows when correction for refraction and earth curvature is not applied: HD = SD * COSξ VD = SD * |SIN|ξ Note: The factory setting for the refraction coefficient K is 0.142. 8.3 Assembling and Disassembling for the Three-jaw Tribrach It is convenient to assemble or disassemble the instrument from the tribrach by loosening or tightening the tribrach clamp.
