This question was posed to me in quiz.

I'd like to ask this question from Position Displacement and Speed Sensing topic in section Engine Electronics of IC Engine

Answer 1

Answer: (c) Calibration

Explanation: Calibration is the process in which standard values of the measurand (the quantity being measured) are applied to the measuring device, and the corresponding output readings of the device are compared with these known standard values. The purpose of calibration is to ensure that the measuring device is accurate and reliable, and to identify any potential deviations or errors in the readings.
