Question 1

What is the primary purpose of a calibration certificate issued after instrument calibration?

Accepted Answer

To document traceability to national or international measurement standards

Answer

A calibration certificate documents that the instrument's measurements are traceable to recognized national or international standards, ensuring measurement integrity.

Question 2

Which term describes the closeness of repeated measurements under the same conditions to each other?

Accepted Answer

Precision

Answer

Precision refers to the repeatability or reproducibility of measurements; accurate instruments are both precise and close to the true value.

Question 3

In calibration, what does 'measurement uncertainty' quantify?

Accepted Answer

The doubt about the validity of a measurement result

Answer

Measurement uncertainty is a parameter that characterizes the dispersion of values that could reasonably be attributed to the measurand.

Question 4

A laboratory balance is found to read 0.05 g high across its entire range. This type of error is called:

Accepted Answer

Systematic error

Answer

A consistent offset across the measurement range is a systematic error, which can often be corrected through calibration adjustment.

Question 5

Which organization provides Canada's primary reference standards for physical measurements?

Accepted Answer

NRC — National Research Council Canada

Answer

The National Research Council Canada (NRC) is Canada's national metrology institute, maintaining primary measurement standards.
