📋 Preview All 15 Mock Test Questions

Q1. An active instrument used for measuring electrical current requires a 12V DC power supply to function. If the power supply fails, what is the expected behavior of the instrument?

  1. It will continue measuring accurately using stored energy.
  2. It will stop functioning and not provide measurements.
  3. It will switch to mechanical measurement mode automatically.
  4. It will provide approximate measurements without power.

Q2. 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

Q3. 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

Q4. 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.

Q5. 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.

Q6. In the context of legal metrology, how does the classification of instruments help in ensuring measurement accuracy and compliance?

  1. By grouping instruments with similar maintenance schedules
  2. By enabling standardized testing and verification procedures
  3. By allowing instruments to be used interchangeably without calibration
  4. By categorizing instruments based on their market price

Q7. Conceptually, what is the primary difference between analog and digital measuring instruments in terms of data representation?

  1. Analog instruments represent data in discrete numerical values, digital instruments use continuous signals.
  2. Analog instruments use continuous signals to represent data, digital instruments use discrete numerical values.
  3. Both analog and digital instruments represent data using continuous signals.
  4. Both analog and digital instruments represent data using discrete numerical values.

Q8. Consider two measuring instruments: Instrument X requires electrical power to operate, while Instrument Y operates solely on mechanical movement. Which classification applies to Instrument X and Instrument Y respectively?

  1. Instrument X - Passive; Instrument Y - Active
  2. Instrument X - Active; Instrument Y - Passive
  3. Both Instrument X and Y are Active
  4. Both Instrument X and Y are Passive

Q9. 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
