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

Repairing a broken instrument

Answer

Cleaning and maintaining measurement equipment

Answer

Replacing worn instrument components

Question 2

'Metrological traceability' means:

Accepted Answer

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

Answer

Recording every measurement made with an instrument

Answer

Storing calibration records in a database

Answer

Using the same instrument for all measurements in a lab

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

The probability that an instrument will fail

Answer

The difference between the highest and lowest readings

Answer

The calibration interval of the instrument

Question 4

What is 'accuracy' in measurement?

Accepted Answer

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

Answer

How closely repeated measurements agree with each other

Answer

The smallest change in input that produces a detectable output change

Answer

The range between the maximum and minimum calibrated values

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

The closeness of a measurement to the true value

Answer

The ratio of measurement uncertainty to the true value

Answer

The range of values over which an instrument operates

Question 6

A 'calibration interval' is defined as:

Accepted Answer

The specified period between successive calibrations of an instrument

Answer

The time required to perform one calibration

Answer

The acceptable tolerance range for a measurement

Answer

The number of calibrations performed per year
