When the bubble is centered, the compensator takes over and maintains a horizontal line of sight. a) 106.591 m The term stadia mark derives from the obsolete unit of distance, the stadion, derived from the Greek measurement of a stadium. the methods described later (see Section 2.6). s= upperhair rod readinglower hair rod reading 1 2 s=( 2.1892.155)= 0.034m s= ( 2.2772.069) =0.208, D= Ks+ c D= Ks+ c Internal focusing telescope: C = 0.

The ratio of focal length to stadia hair spacing is a constant for an instrument and is identified as K, the stadia interval factor, i.e., K f i = Thus the distance from the instrument operator's eye to the rod is D = K I Thus the student records the top and bottom readings on the rod and calculates the distance using The term stadia comes from a Greek unit of length Stadion (equal to 600 Greek feet, pous) which was the typical length of a sports stadium of the time. including the 10 cm end sections of the stake.

In plaats van een betrouwbaarheidsinterval wordt de precisie van een onderzoek ook vaak uitgedrukt in de p-waarde. The total correction for curvature and refraction (C&R) must be determined for each far-rod reading using the distance from the instrument to the far rod as the argument. 2. Step 6. the two boards, which should be 1.70 m, into 10 cm sections.

There are three types of levels used in differential levelingautomatic, digital, and optical-micrometer. Instruments equipped with a stadia circle or a Beaman arc have multipliers on the vertical circle for both H and V, thus eliminating the need to measure vertical angles. Instruments with a SIF of 1:333 may not have a C-factor of greater than 0.010. If PF = 0.75 m, ABCD = 424 x 0.75 m = 318 m. Note: to avoid errors when counting your steps: 10.
