Question 1

What is 'calibration' in a measurement context?

Accepted Answer

The process of comparing a measuring instrument against a known reference standard to detect and document deviations

Answer

Calibration compares an instrument's output against a traceable reference standard to determine its accuracy and document any deviations.

Question 2

'Metrological traceability' means:

Accepted Answer

An unbroken chain of calibrations linking a measurement back to national or international measurement standards

Answer

Metrological traceability establishes a documented, unbroken chain of calibrations from the instrument through reference standards up to national or international standards such as NIST.

Question 3

'Measurement uncertainty' in calibration represents:

Accepted Answer

A quantified expression of doubt about the measurement result, accounting for all identified sources of error

Answer

Measurement uncertainty is a parameter that characterizes the range of values within which the true value is estimated to lie, considering all significant error sources.

Question 4

What is 'accuracy' in measurement?

Accepted Answer

How closely a measurement result agrees with the true or accepted reference value

Answer

Accuracy describes how close a measurement is to the true or accepted reference value, distinguishing it from precision which is about repeatability.

Question 5

What is 'precision' in the context of measurement systems?

Accepted Answer

The degree of agreement among repeated independent measurements under the same conditions

Answer

Precision refers to the repeatability or reproducibility of measurements — how consistently an instrument gives the same result under unchanged conditions.
