STATIC CHARACTERISTICS OF INSTRUMENTS & CALIBERATION

Question 1

Define static and dynamic characteristics

Answer 1

Static –> Here the measurands are either constant or change very slowly.

Dynamic –> Here the measurands constantly change, or are dynamic.

Question 2

What is Resolution

Answer 2

This is the least count of your instrument.

Question 3

What is Threshold

Answer 3

range of different input values over which there is no change in output value in starting.

Question 4

Difference in Repeatability and Reproducibility.

Answer 4

Repeatability –> Repetition of a measurement in the same place, conditions, machine and the same operator is called repeatability. Repeatability coeff which is the absolute difference between the pair of the repeated results is also calculated.

Reproducibility –> Reproducibility is the degree of agreement between the results of experiments conducted by different individuals, at different locations, with different instruments.
