Introduction

Calibration Test

A calibration test is a procedure in which an instrument, tool, or

device is tested to confirm that it conforms with the standard. Calibration

is very important, as it ensures that objects are working properly. There

are a number of reasons to conduct a calibration test, ranging from

concerns that something is not working as it should to preparations for an

event in which very precise calibration is desired, and there are a number

of ways to perform a calibration.

In some cases, people may conduct their own calibration tests. For

eample, a supermarket might check the accuracy of its scales every

week with an object of a known weight. !arket employees would "ero out

the scales, place the object on the scale, and take a reading before

"eroing the scale out again and weighing a second time. For

thoroughness, several different weights would be tried, to confirm that the

scale can handle a range of weights. If inaccuracies were identified, the

scales would need to be repaired, adjusted, or replaced. Calibration test

kits are available for many common instruments and tools so that peoplecan perform e#uipment calibration on their own.

Objectives

To test the instrument wheather it can function

properly after doing $ifferential Field Test.

To test wheather the reading distance in the same

position is consistent.

Test is carried immediately after servicing.

To test the instrument upon receipt of as new

instrument.

Coordinate measurement

Coordinates of an unknown point relative to a known coordinate can be determined using the total

station as long as a direct line of sight can be established between the two points. Angles and distancesare measured from the total station to points under survey, and the coordinates (X, Y, and Z or

northing, easting and elevation of surveyed points relative to the total station position are calculated

using trigonometry and triangulation. !o determine an absolute location a !otal "tation re#uires line

of sight observations and must be set up over a known point or with line of sight to $ or more points

with known location.

%or this reason, some total stations also have a &lobal 'avigation "atellite "ystem interface which do

not re#uire a direct line of sight to determine coordinates. owever, &'"" measurements may re#uire

longer occupation periods and offer relatively poor accuracy in the vertical a)is.

Angle measurement

*ost modern total station instruments measure angles by means of electro+optical scanning of

e)tremely precise digital bar+codes etched on rotating glass cylinders or discs within the instrument.

!he best #uality total stations are capable of measuring angles to .- arc+second. ne)pensive

/construction grade/ total stations can generally measure angles to - or 0 arc+seconds.

Distance measurement

*easurement of distance is accomplished with a modulated microwave or infrared carrier signal,

generated by a small solid+state emitter within the instrument1s optical path, and reflected by a prism

reflector or the ob2ect under survey. !he modulation pattern in the returning signal is read and

interpreted by the computer in the total station. !he distance is determined by emitting and receiving

multiple fre#uencies, and determining the integer number of wavelengths to the target for each

fre#uency. *ost total stations use purpose+built glass corner cube prism reflectors for the 34* signal.

A typical total station can measure distances with an accuracy of about 0.- millimetres (.56 ft 7 $

parts per million over a distance of up to 0,- metres (5,6 ft.8$9

:eflectorless total stations can measure distances to any ob2ect that is reasonably light in color, to a

few hundred meters.

Data processing

"ome models include internal electronic data storage to record distance, hori;ontal angle, and vertical

angle measured, while other models are e#uipped to write these measurements to an e)ternal data

collector, such as a hand+held computer.

Conclusion

=>?3* have made a circular to license surveyor to understand about this

calibration,the method it was and how to make a report after make the calibration

test."urveyor need to check the 34* or !otal "tation few times,and make a calibration

after @ months using the instrument.esides that,after making a calibration,the surveyor

need to record all the data in booking reform and make the calculation to know the

error,in fact there have the error can be accepted and cannot be accepted.!hat is why the

surveyor need to make a calculation after they finish the calibrated the instrument.

ased on the fieldwork of calibration test that we have done by following all of the

procedurs,we get +.0m or +0.mm."o,it show that the error are accepted because

the error based on ?ek.Betua ?engarah >kur 4an ?emetaan il.@$6 the error should

not more that 0mm.owever,after finished our calibration test for 34*, we get +.0

so it is accepted.Conclusion, the 34* do not have any problem.
