Question 1

'Bias' in a measurement system is defined as:

Accepted Answer

The systematic difference between the average of multiple measurements and the true reference value

Answer

The random error present in all measurements

Answer

The variation between different operators using the same gauge

Answer

The drift in a gauge reading over time

Question 2

In measurement system management, 'stability' refers to:

Accepted Answer

The change in bias of a measurement system over time when measuring the same reference part

Answer

The physical sturdiness of the measuring instrument

Answer

The ability to measure parts of different sizes

Answer

The consistency of measurements made by different operators

Question 3

What does 'as-found' vs. 'as-left' mean in calibration records?

Accepted Answer

As-found is the condition of the instrument when received for calibration; as-left is the condition after calibration and any adjustments

Answer

As-found is after adjustment, as-left is before adjustment

Answer

Both terms refer to the same measurement

Answer

As-found refers to the calibration standard, as-left refers to the unit under test

Question 4

'Linearity' in a measurement instrument refers to:

Accepted Answer

The consistency of bias across the instrument's full operating range

Answer

The ability to measure in a straight line

Answer

The relationship between repeated measurements made by the same operator

Answer

The time required to reach a stable reading

Question 5

The '10:1 rule' in calibration refers to:

Accepted Answer

The ratio between the accuracy of the calibration standard and the accuracy of the instrument being calibrated

Answer

Calibrating instruments 10 times per year

Answer

The number of measurements required for a valid calibration

Answer

The acceptable percentage of instruments that can be out of tolerance

Question 6

According to ISO/IEC 17025, a calibration laboratory's quality management system must ensure:

Accepted Answer

Technical competence, impartiality, and consistent application of traceable measurement methods

Answer

All calibrations are performed at NIST headquarters

Answer

Every instrument is calibrated daily

Answer

Calibration results are kept confidential from customers
