2026&2027
1. Which SI base unit is used for the measurement of thermodynamic temperature?
A. Degree Celsius
B. Kelvin
C. Fahrenheit
D. Joule
Answer: B
The kelvin is the SI base unit for thermodynamic temperature. Celsius is commonly used in
practice, but the kelvin is the corresponding SI base unit.
2. A calibration technician needs to convert 0.0045 A into milliamperes. What is the correct
value?
A. 0.045 mA
B. 0.45 mA
C. 4.5 mA
D. 45 mA
Answer: C
One ampere equals 1,000 milliamperes. Therefore, 0.0045 A × 1,000 = 4.5 mA.
3. Which SI-derived unit is equivalent to one volt?
A. Joule per coulomb
B. Newton per meter
C. Coulomb per second
D. Watt per ampere-hour
Answer: A
A volt is defined as one joule of energy per coulomb of electric charge.
4. A laboratory needs to demonstrate that a temperature measurement can be related to
recognized national or international standards through an unbroken chain of comparisons.
Which concept is being demonstrated?
A. Resolution
,B. Sensitivity
C. Traceability
D. Repeatability
Answer: C
Metrological traceability is established through a documented, unbroken chain of calibrations
connecting a measurement result to an appropriate reference.
5. Which type of standard is normally maintained at the highest level of a laboratory's
measurement hierarchy and used as the basis for lower-level standards?
A. Working standard
B. Primary standard
C. Transfer standard
D. Check standard
Answer: B
A primary standard represents a high-level reference against which lower-level standards can
ultimately be related.
6. A technician repeatedly measures the same artifact under the same conditions and
obtains values that are tightly grouped but consistently different from the accepted value.
Which characteristic is most evident?
A. High repeatability with bias
B. High reproducibility with zero bias
C. Poor resolution with no error
D. High sensitivity with perfect accuracy
Answer: A
Tightly grouped results indicate good repeatability, while consistent displacement from the
accepted value indicates bias.
7. A pressure gauge has a range of 0 to 1,000 psi and a stated accuracy of ±1% of full scale.
What is the maximum accuracy error at any point in the range?
A. ±0.1 psi
B. ±1 psi
C. ±10 psi
D. ±100 psi
Answer: C
One percent of the 1,000-psi full-scale range is 10 psi, so the stated accuracy corresponds to
±10 psi.
,8. Which measurement method involves replacing a reference standard with the unit under
test while maintaining essentially the same measurement conditions?
A. Differential method
B. Substitution method
C. Direct method
D. Ratio method
Answer: B
The substitution method compares the UUT and reference by substituting one for the other
under controlled measurement conditions.
9. A digital instrument displays 12.347 V while its specification allows only three decimal
places. What measurement characteristic primarily determines the smallest displayed
increment?
A. Bias
B. Linearity
C. Resolution
D. Reproducibility
Answer: C
Resolution describes the smallest increment or change that a measurement system can
distinguish or display.
10. A technician obtains nearly identical results when measuring the same artifact several
times using the same instrument, operator, and procedure. Which characteristic is being
evaluated?
A. Repeatability
B. Reproducibility
C. Drift
D. Hysteresis
Answer: A
Repeatability concerns agreement among repeated measurements under substantially
identical conditions.
11. Which condition is most likely to increase uncertainty during precision resistance
measurements?
A. Controlled ambient temperature
B. Stable reference standard
C. Temperature variation affecting the resistor
D. Properly documented procedures
Answer: C
, Resistance can vary with temperature, so uncontrolled temperature changes can contribute
directly to measurement uncertainty.
12. A calibration laboratory receives an instrument with no identification number and no
ownership information. What should the technician do first?
A. Calibrate it and assign a result later
B. Create an identification record before processing it
C. Place it immediately into service
D. Change its calibration interval
Answer: B
Positive identification is essential for controlling calibration status, history, ownership, and
traceability throughout the process.
13. Which document normally provides the specific sequence, equipment, environmental
conditions, and acceptance criteria required to perform a calibration?
A. Calibration procedure
B. Purchase order
C. Training record
D. Customer invoice
Answer: A
A calibration procedure defines how the calibration is to be performed and what conditions
and criteria apply.
14. A calibration technician discovers that a reference standard's calibration certificate
expired yesterday. The standard is scheduled for use today. What is the most appropriate
action?
A. Use it because the expiration is only one day old
B. Change the certificate date manually
C. Use it only for low-accuracy instruments
D. Prevent its use until its status is resolved
Answer: D
A standard with unresolved calibration status should not be used because its suitability and
traceability have not been established.
15. Which environmental factor can significantly affect dimensional calibration of
precision components?
A. Ambient temperature
B. Office lighting alone
C. Document font size
D. Equipment ownership
