Sensitivity
The sensitivity is an important specification for a spirit level. The overall accuracy of the device depends on its sensitivity. The sensitivity of a level is defined as the change of angle or gradient required to move the bubble by unit distance. If the bubble housing has graduated divisions then the sensitivity refers to the angle or gradient change required to move the bubble by one of these divisions. Sensitivity of a spirit level is expressed in mm/m. 2mm is the standard spacing for graduations. The standard sensitivity for a machinst level is .0005 inch per 2mm division (10 seconds arc).

Famous quotes containing the word sensitivity:
“The vanity of men, a constant insult to women, is also the ground for the implicit feminine claim of superior sensitivity and morality.”
—Patricia Meyer Spacks (b. 1929)
“Freedom of choice for women, at the expense of the caring, warmth, and sensitivity to others so often associated with them, may be empty. In the thrust to redefine male and female roles, women must not become men; nor can men be permitted the continual dehumanization of their roles.”
—Kathleen Weibel (b. 1945)
“The sensitivity of men to small matters, and their indifference to great ones, indicates a strange inversion.”
—Blaise Pascal (1623–1662)
