Thanks Metrology Quiz The degree of perfection used in instruments, the methods and the observations, is known as Least count Precision Accuracy Error Analytical checking of gears includes checking of? Vibrations All of the above Noise level Tooth profile Which type of comparator changes its magnification, when distance between cross strip hinge and knife edge is varied? Projector Comparator Johansson Mickrocator Sigma comparator Solex Pneumatic Comparator Which principle is used to measure distance in electronic comparator? Frequency modulation Both a. and b. Radio oscillations None of the above How is interference between shaft and hole calculated? Interference = minimum shaft + maximum hole Interference = minimum shaft – maximum hole Interference = maximum shaft – minimum hole None of the above The sensitivity of back pressure air gauge is given by the relation shown below, what does δ R / δ p² signify? (δR / δt) = (δ Am / δ t) x (δ R / δ p² ) x (δ p² / δ Am ) Overall magnification Measuring head sensitivity Pneumatic sensitivity Sensitivity of pressure gauge Which among the following causes first order surface irregularity?
