6.6. Performing Observation of Inclination

For this measurement the reference direction is the compensated vertical scale.
1. With the probe on the top of the telescope, set the telescope NU to the mean value MM or
(MM + 180º) on the horizontal circle, corresponding to the north observation of D, and lock
the horizontal circle.
2. Rotate the telescope in the vertical plane and obtain the (NU) and (SD) null magnetic
measurements.
3. Rotate the telescope to MM or (MM + 180º) on the horizontal circle, corresponding to the
south observation of D. Lock the horizontal circle and rotate the telescope in the vertical
plane to obtain the SU and ND null magnetic measurements.
4. Calculate the Inclination, I

= 170º
= (ED+ WD + EU + WU)/4
= (194º + 14º + 14º + 194º)/4
= 104º
= MM + (-30°) - TD ± 90°
= 104º - 30º - 170º + 90º = - 6º - Select
= 104º - 30º- 170º - 90º = - 186º - Reject
= [(360º - ND) + (180º - SU) + (SD - 180º) + NU] /4
= 300º, SU = 120º, SD = 240º, NU = 60º
= (60º + 60º + 60º +60º) / 4 = 60º
