<br />
 .<br />
<br />
Calipers are used to measure the outside diameter of the cylinder , the depth of the tube , and the inside diameter . Accuracy was 0.1 mm or 0.01 cm<br />
How to measure :<br />
Read the scale fixed<br />
Coupled with the search for the straight line between the fixed scale and Nonius scale ( below )<br />
<br />
3 . Micrometer screw<br />

<br />
<br />
Micrometer screw is generally used to measure the diameter of the ball / cylinder and the thickness of a thin plate and datar.Ketelitian reached 0.01 mm or 0.001 cm .<br />
How to use :<br />
Satuanya : mm<br />
Value of each scale 0.5 mm<br />
Nonius scale roll:<br />
unit -  mm<br />
Each scale : 0.01 mm<br />
The final result is the sum of the values on the main scale to scale rotary Nonius<br />
<br />
<br />
Measurement accuracy<br />
Precision measuring instruments is determined by :<br />
Accuracy = 1/2 x smallest scale<br />
<br />
<br />
1 . Ruler has accuracy = 1/2 mm<br />
2 . Vernier caliper has ketilitian = ½ x 0.1 mm = 0.05 mm<br />
3 . Has a precision micrometer screw = ½ x 0.01 mm = 0.005 mm<br />
<br />
Important figures<br />
<br />
1 . All numbers except the zeros are significant figures<br />
2 . Number of zeros is trivial if :<br />
• The zero flanked by a nonzero number of significant figures<br />
Example : 304<br />
• The zero on the right number of significant figures merupkan nonzero if given a special mark ( niasanya with an underscore )<br />
example :<br />
3.50 cm has three significant figures<br />
2.50 cm memilii two significant figures<br />
3 . Zeros on the left who are non-zero numbers are significant figures not<br />
example :<br />
• The length of 0.72 cm cube has two significant figures<br />
• The length of 0.0702 cm cube has three significant figures<br />
• The length of 0.7020 cm beam has three significant figures<br />
• The length of 0.7020 cm cube has four significant figures<br />
<br />
<br />
Measurement results reported<br />
Measurement results is not absolute results , but one of the values that may be a number of measurement results . Due to the measurement results are reported as a range of possible values stated the actual length of objects<br />
example<br />
An object is measured with a ruler that has the smallest scale 1mm .<br />
Ketelitien bar 0.5 mm<br />
Results of measurement 4.44 cm , then the length of the actual object that is probably the<br />
Minimum value = ( 4.44 to 0.5 ) mm<br />
Maximum value = ( 4.44 +0.5 ) mm<br />
<br />
Usually measurement results are reported as ( 4.44 ± 0.5 ) . Meaning of this paper that the measurement results may not exceed 0.5 mm . .
