PROF 6 Angle measurement 1 Turn the telescope to the given point Use the rough optical sighting device to aim at the object Then rotate the eyepiece in the counter clockwise direction until the clear image of reticule Turn the focussing sleeve of the telescope so that the object will be cleariy imaged on the graduated plate 2 Fix the position of telescope with the help of horizontal 15 and vertical 19 clamps Turn both horizontal and vertical micrometer screws 17 and 18 so that the telescope is precisely aimed at the target to be measured At this moment move the eye left and right and then up and down In doing so no relative displacement should be detected between the target image and the graduation marks on the graduated plate This means that no parallax exist 3 With the rotatory circle 6 set the reading up to 0 0 minutes Horizontal graduated circle reading 35 03 3 H window Vertical graduated circle reading 35 58 0 V window 7 Graduated circle reading After illuminating the graduated circle adjust the reading eyepiece 4 so that the reading visual field as shown in Fig 6 can be seen distinctly The symbols H and V indicate the readings of the horizontal and the vertical circles respectively There are 60 graduations to every division T on the tape and so estimation readings up to 0 1 And the reading error 0 05 0 1 of the graduated circle corresponds to 3 6 angular sec The system of readings of vertical angles starts from the horizon 90 Before making the reading on the vertical circle it is necessary to turn the locking knob 10 of the automatic compensator to enable the compensator index mechanism to be in a free state At this moment very distinct sound is audible And only then you can take the readings of the vertical circle Flg 6B 28 MEASUREMENT FOUNDATION
