  2. An instrument that indicates measurement values using a continuous scale or pointer.
  3. An instrument that stores measurement data electronically for later analysis.
  4. An instrument that uses binary code to represent measurement values.

Q5. 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

Q6. 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.

Q7. 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.
