Introduction to Metrology

The degree of closeness of the measured value of a certain quantity with its true value is known as.......?

• Accuracy

• Precision

It is concern with the accuracy of measurements where these have influence on the transparency of economical transactions, and health and safety.

• Scientific Metrology

• Industrial Metrology

• Fundamental Metrology

• Legal Metrology

It is the susceptibility of a measurement device to have its indicators converted into meaningful numbers

• Readability

• Precision

• Inspection

• Error

It is the relationship between values of quantities indicated by a measuring instrument and the corresponding value realized by standards.

• Calibration

• Expectation

• Precision

• Range

It is called fundamental method and it is based on the measurement of the base quantities used to define a particular quantity.

• Substitution Method

• Comparison Method

• Absolute Method

• Coincidence Method

The value of the quantity to be measure is obtained directly without any calculation.
