Technology and Engineering Mapping And Surveing Department AUTOLEVELL AND THEODOLITE INTRODUCTION

Description of Aitolevel An autolevel is a kind of instrument, scope in surveying and mapping which is usual to measure the difference oh high between certain point and others point. And also uses in measuring distance, which is called optical distance Technology and Engineering

Kinds of Autolevel Rigid aotolevel This instrument has a very simple construction. The characteristics are as follow: The viewfinder line is perpendiculair with the first spindle. The nivo alignment is equal with the viewfinder’s line The nivo alignment is perpendiculair with the first spindle Technology and Engineering

PART OF RIGID AUTOLEVEL Description of image 1 : Telescope: there are objective and oculair lens inside, also alignment, a shadow line which connecting intersection with the diaphragm cross thread Nivo tube: it is used as the setting of guideline, in order that the alignment is equal with the reference line Oculair lens : a lens at the back of the telescope Centering set screw : three screws to set the bubble of the nivo in order that it’s the position will be in the centre Technology and Engineering

PART OF RIGID AUTOLEVEL Objective lens : a lens in front of the telescope Top standard: main base where the top of the three screws located Ring/ diaphragm regulator : instrument to set the target picture Bottom standard : base that support the static head Technology and Engineering

2. Up Down autolevel In this instrument, the top and the bottom part is separated by a hinge. So that the telescope can play up or down to make the position of the alignment is perpendiculair with the first spindle. Technology and Engineering

PART OF UP DOWN AUTOLEVEL Pay attention on this image : Telescope A Nivo Tube Ocular lens B B Alignment Top Standard Objective lens Lever screw Centering set screw Bottom satndard A Image 2 : Up Down Autolevel Technology and Engineering

PART OF UP DOWN AUTOLEVEL Description : Telescope: it is different from telescope in rigid autolevel because there is a nivo tube in it. Nivo tube : nivo used as a guideline of perpendicular of alignment and nivo reference line Top standard : place of nivo box and hinge Up down screw : to play telescope up or down so that the nivo balance is in balance. Bottom standard : base that support the static head Technology and Engineering

PART OF UP DOWN AUTOLEVEL Centering set screw : the three screws to set the nivo bubble so that the first spindle is perpendicular with the reference field. Nivo box : nivo as a guideline for the first spindle perpendicular with the nivo reference field Hinge : connector between top and bottom part in order taht the telescope can be played up or down Technology and Engineering

3. Automatic Autolevel This instrument has been completed with an automatic compensator. Although the factory doesn’t make the alignment perpendicular with the first spindle, but, if the nivo bubble is in the centre, it is automatically that all the conditions has completed. Technology and Engineering

PART OF AUTOMATIC AUTOLEVEL Description : Bottom Standard: base that support on static head and has locker screw hole Centering set screw : the three screws to set the nivo bubble so that the first spindle is perpendicular with the reference field. Top Standard : location of nivo box and hinge . Telescope: consist of three parts: objective lens, upholder prism (a and b), two autofocus lens, two glasses for cross thread diaphragm scratches, and three parts of lens to set the shadow of cross thread Technology and Engineering

PART OF AUTOMATIC AUTOLEVEL Flat circle : a circle where the angle scale is written from 0 degree up to 360 degree. Autofocus knob : a knob to set the sharpness of the target which there is a point so that it can move in every direction Technology and Engineering

DESCRIPTION OF THEODILITE Theodolite is an instrument in surveying and mapping scope. This instrument is used in measuring flat angle, zenith, and also measuring optical distance through tachymetry method. Technology and Engineering

PART OF THEODOLITE 1. Top Part a. Telescope which has no differnces with autolevel, completed with alignment. b. Vertical scale circle c. Flat spindle where the telescope and the vertical circle can move around. d. Flat circle index reading Technology and Engineering

PART OF THEODOLITE 2. Middle Part a. Buffer; supporting flat spindle. b. Flat circle index reading which is concentric with the first flat circle c. Vertical spindle, where the top and the middle part can go around it. d. Nivo tube, to set spindle and nivo reference field must be in perpendicular. Technology and Engineering

PART OF THEODOLITE 3. Bottom Part a. Flat scale circle which rotate the vertical spindle. b. Tripod c. Three base screws Technology and Engineering

KIND OF THEODOLITE 1. Reiteration Theodolite An instrument to measure flat/hillside angle, optical distance, and high differences. Flat scale circle is ignited on the box, so that the flat scale cannot be played. Flat circle reading for certain target can’t be set into zero point. Angle which formed by alignment is focused on two targets: 1. Top Angle ( M – B) 2. Bottom Angle ( B – M) Technology and Engineering
