Question
The direct and reversed zenith angles observed by a theodolite are 56° 00' 00" and 303° 00' 00", respectively. What is the vertical collimation correction?
A.
+1° 00' 00"
B.
-1° 00' 00"
C.
-0° 30' 00"
D.
+0° 30' 00"
Answer ( Option D)

+0° 30' 00"

Solution

Given, 
Φ= Observed value of direct zenith angle 
  = 56° 00' 00" 
Φ= Observed value of reversed zenith angle
  = 303° 00' 00" 
So, Vertical collimation correction
= +0.5° = +30'
