ENGINEERING METROLOGY and MEASUREMENTS TWO MARK QUESTIONS AND ANSWERS UNIT I- Concept Of Measurement 1. What is Range of measurement?: The physical variables that are measured between two values. One is the higher calibration value H , and the other is Lower value L, The difference between H, and L, is called range. 2. . What is Resolution: The minimum value of the input signal is required to cause an appreciable change in the output known as resolution. 3. Differentiate between sensitivity and range with suitable example. Example: A Instrument have a scale reading of 0.01mm to 100mm. Here, the sensitivity of the instrument is 0.0lmm i.e. the minimum value in the scale by which the instrument can read. The range is 0.01 to 100mm i.e. the minimum to maximum value by which the instrument can read. 4. Define system error and correction., Error: The deviation between the results of measured value to the actual value. Correction: The numerical value which should be added t...
