Q1. Scenario: An inspector is evaluating two measuring instruments for a legal metrology application: Instrument X is analog with a mechanical pointer, and Instrument Y is digital with an LCD display. Which of the following statements is most accurate regarding their classification and characteristics?

  1. Instrument X is classified as analog because it uses a continuous scale, while Instrument Y is digital because it displays discrete numerical values.
  2. Instrument X is digital because it uses a pointer, and Instrument Y is analog because it uses an LCD display.
  3. Both instruments are analog since they measure the same physical quantity.
  4. Both instruments are digital because modern instruments always use electronic displays.

Q2. In a scenario where an active instrument and a passive instrument are used to measure the same physical quantity, which of the following statements is generally true?

  1. Active instruments usually provide higher sensitivity and faster response.
  2. Passive instruments always provide more accurate measurements.
  3. Active instruments do not require calibration.
  4. Passive instruments consume more power than active instruments.

Q3. An inspector is using an analog pressure gauge to measure the pressure in a gas cylinder. The gauge has a scale from 0 to 100 psi with 1 psi divisions. If the pointer is halfway between 45 psi and 46 psi, what is the approximate pressure reading?

  1. 44.5 psi
  2. 45.5 psi
  3. 46.5 psi
  4. 45.0 psi

Q4. A flow measuring instrument is classified as volumetric and uses the displacement principle. If the instrument measures 15 liters in 3 minutes, what is the flow rate in liters per minute?

  1. 5 liters per minute
  2. 45 liters per minute
  3. 0.2 liters per minute
  4. 18 liters per minute

Q5. Calculate the reading on a passive mechanical dial gauge if the pointer deflects by 15 divisions, each division representing 0.02 mm. What is the measured displacement?

  1. 0.3 mm
  2. 0.15 mm
  3. 3 mm
  4. 0.02 mm

  1. Active measuring instrument
  2. Passive measuring instrument
  3. Electronic measuring instrument
  4. Digital measuring instrument

Q7. An inspector encounters two measuring instruments: one uses a mechanical spring principle, and the other uses an electronic sensor. According to classification, these instruments belong to which categories respectively?

  1. Mechanical and Electrical
  2. Electronic and Mechanical
  3. Electrical and Hydraulic
  4. Hydraulic and Pneumatic

Q8. Calculate the power consumption in watts of an active measuring instrument operating at 24 volts and drawing a current of 0.5 amperes.

  1. 12 W
  2. 48 W
  3. 0.48 W
  4. 24 W

Q9. Consider two digital instruments measuring the same parameter: Instrument X uses a resistive sensor, while Instrument Y uses a capacitive sensor. Which factor is most likely to differ significantly between these two instruments?

  1. The type of digital display used
  2. The principle of sensing the physical quantity
  3. The unit of measurement displayed
  4. The legal metrology certification process

Q10. An inspector is verifying a digital weighing scale used in a market. Which characteristic is most critical to check to ensure legal compliance?

  1. The color of the digital display
  2. The scale's ability to display measurements in digital format with correct units
  3. The weight of the scale itself
  4. The presence of a mechanical dial alongside the digital display

Q11. Consider two measuring instruments: one passive and one active. Which characteristic is unique to passive instruments?

  1. They require batteries or external power to function.
  2. They measure quantities without altering them or needing power.
  3. They provide digital readouts through electronic circuits.
  4. They can automatically calibrate themselves during measurement.

Q12. Which of the following best defines an active measuring instrument in the context of legal metrology?

  1. An instrument that requires an external power source to operate.
  2. An instrument that measures quantities without any energy input.
  3. An instrument that only records measurements passively.
  4. An instrument that uses mechanical parts exclusively for measurement.

Q13. Which of the following best describes the primary basis for classifying measuring instruments in legal metrology?

  1. The physical size of the instrument
  2. The principle of measurement employed
  3. The country of manufacture
  4. The color and design of the instrument
