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


Kinds of Autolevel

1. Rigid aotolevel This instrument has a very simple

construction. The characteristics are as follow:

1. The viewfinder line is perpendiculair with the first spindle.

2. The nivo alignment is equal with the viewfinder’s line

3. The nivo alignment is perpendiculair with the first spindle

Description of image 1 :o Telescope: there are objective and oculair lens

inside, also alignment, a shadow line which connecting intersection with the diaphragm cross thread

o Nivo tube: it is used as the setting of guideline, in order that the alignment is equal with the reference line

o Oculair lens : a lens at the back of the telescopeo Centering set screw : three screws to set the

bubble of the nivo in order that it’s the position will be in the centre



o Objective lens : a lens in front of the telescope

o Top standard: main base where the top of the three screws located

o Ring/ diaphragm regulator : instrument to set the target picture

o Bottom standard : base that support the static head


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.

Description :o Telescope: it is different from telescope in rigid

autolevel because there is a nivo tube in it.o Nivo tube : nivo used as a guideline of

perpendicular of alignment and nivo reference lineo Top standard : place of nivo box and hingeo Up down screw : to play telescope up or down so

that the nivo balance is in balance. o Bottom standard : base that support the static

head



o Centering set screw : the three screws to set the nivo bubble so that the first spindle is perpendicular with the reference field.

o Nivo box : nivo as a guideline for the first spindle perpendicular with the nivo reference field

o Hinge : connector between top and bottom part in order taht the telescope can be played up or down


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.

so that the first spindle is perpendicular with the reference field.

o Top Standard : location of nivo box and hinge .o 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


PART OF AUTOMATIC AUTOLEVEL

o Flat circle : a circle where the angle scale is written from 0 degree up to 360 degree.

o Autofocus knob : a knob to set the sharpness of the target which there is a point so that it can move in every direction


Kinds of Model of Autolevel

This model is Wildbeerburg Swizertland autolevelThis instrument is used for measuring high differences and measuring distance In survey and maping job, this instrument is used for determining vertical position



This is model Nicon AP-5 Japan fabrication.This instrument is used for measuring high differences and measuring distance In survey and maping job, this instrument is used for determining vertical position



This is model Topcon AT-F4 Japan fabrication. This instrument is used for measuring high differences and measuring distance In survey and maping job, this instrument is used for determining vertical position



This is model Topcon AT-F4 Japan fabrication. This instrument is used for measuring high differences and measuring distance In survey and maping job, this instrument is used for determining vertical position


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.


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


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.


PART OF THEODOLITE

3. Bottom Part a. Flat scale circle which rotate the vertical

spindle. b. Tripod c. Three base screws


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)

1. Repetition Thedolite Principally, this instrument is not different

with reiteration theodolite. However, they have differences in the construction. The flat scale circle can be played (up to 0 degree) and also can rotate the vertcal spindle.
