What is accuracy?
Ability of an instrument to show exact reading
Ability of an instrument to show multiple reading continously
Ability of an instrument to repeat the reading exactly
Ability of an instrument to give consistent reading
What is precision?
Capability of an instrument to give exact reading each time
Capability of end user to come up with exact result
Capability of an instrument to give same reading each time
Capability of instrument to erase erroneous results
What is tolerance?
Ability of user to tolerate mistakes
Maximum error expected in an instrument
Minimum standard deviation allowed in an instrument
Max deviation of an output component at an certain value
Choose the correct static characteristics for 'range of reading between min value and max value for the measurement instrument'
Bias
range of accuracy
range of linearity
range of span
What is Bias?
Difference between range of standard deviation
Error happen due to parallax error
Constant error occurs during the measurement of an instrument
Error bar resulted from false positive
Max deviation from the reading of 'X' and the straight line. Name this static characteristics.
Linearity
Severity
Bipolar Complexity
Linear equation of state
What is Sensitivity?
Ability of an instrument to detect smaller input at steady state
ratio of smaller input that bring bigger output at steady state
Bigger input that results smaller output at dynamic condition
Ratio of change in output towards the change in input at steady state condition
What is Dead Space/ Dead Band
range of different input values when there is no change in output value (unresponsive system)
scale of input values that goes undetected under certain band
range of probability of a signal that fall on dead space
scale of band that is unresponsive with input
What is resolution?
Smallest change in input that makes significant output reading
Smallest change in input reading that can be traced accurately
Biggest change in input given in pixel
Smallest change in pixel that results in clear image
What is drift?
Drag race that results in winner take all
variation of handling instrument that results an inconsistent output
Small input that results in dead band
variation in the instrument output which is not cause by any change of input
