Ability of an instrument to show exact reading

b)

Ability of an instrument to show multiple reading continously

c)

Ability of an instrument to repeat the reading exactly

d)

Ability of an instrument to give consistent reading

2.

What is precision?

a)

Capability of an instrument to give exact reading each time

Capability of end user to come up with exact result

c)

Capability of an instrument to give same reading each time

d)

Capability of instrument to erase erroneous results

3.

What is tolerance?

a)

Ability of user to tolerate mistakes

b)

Maximum error expected in an instrument

c)

Minimum standard deviation allowed in an instrument

d)

Max deviation of an output component at an certain value

4.

Choose the correct static characteristics for 'range of reading between min value and max value for the measurement instrument'

a)

Bias

b)

range of accuracy

c)

range of linearity

d)

range of span

5.

What is Bias?

a)

Difference between range of standard deviation

b)

Error happen due to parallax error

c)

Constant error occurs during the measurement of an instrument

d)

Error bar resulted from false positive

6.

Max deviation from the reading of 'X' and the straight line. Name this static characteristics.

a)

Linearity

b)

Severity

c)

Bipolar Complexity

d)

Linear equation of state

7.

What is Sensitivity?

a)

Ability of an instrument to detect smaller input at steady state

b)

ratio of smaller input that bring bigger output at steady state

c)

Bigger input that results smaller output at dynamic condition

d)

Ratio of change in output towards the change in input at steady state condition

8.

What is Dead Space/ Dead Band

a)

range of different input values when there is no change in output value (unresponsive system)

b)

scale of input values that goes undetected under certain band

c)

range of probability of a signal that fall on dead space

d)

scale of band that is unresponsive with input

9.

What is resolution?

a)

Smallest change in input that makes significant output reading

b)

Smallest change in input reading that can be traced accurately

c)

Biggest change in input given in pixel

d)

Smallest change in pixel that results in clear image

10.

What is drift?

a)

Drag race that results in winner take all

b)

variation of handling instrument that results an inconsistent output

c)

Small input that results in dead band

d)

variation in the instrument output which is not cause by any change of input
