  Hints for Quick recall/revision Unit 1 1. Metrology : Science of Measurement with agreed units and methods 2. Types of metrology :  use short form LIDS   to recall types LIDS means L : legal metrology    I : Industrial metrology  D : Deterministic   metrology  S : Scientific metrology 3. Instrument characteristics :   use short form APSC   to recall types Accuracy : Closeness with true value of measurement Precision : Repeatability of  same measurement in  similar conditions of measurement Sensitivity : Ability to detect small input variations by instrument Calibration : Checking instrument scale with certified standards.   Slip gauges are used as a standards for calibration of vernier, micrometer 4. Errors : Types : Systematic or controllable errors   and Random ( Accidental errors) Reading error : Parallax error  Observer's direction should be pro...
