The method to use a vernier scale or caliper with zero error is to use the formula'actual reading = main scale + vernier scale " ( zero error )'thus the actual reading is 19.00 + 0.54 " ( 0.10 ) = 19.44 mm

Guide bars in the x, y and z directions ( or alternatively, in the polar coordinate holder ), fitted with high precision vernier scales allow the neurosurgeon to position the point of a probe ( an electrode, a cannula, etc . ) inside the brain, at the calculated coordinates for the desired structure, through a small trephined hole in the skull.

(unindent ) I made a more compact test file at User : 84user / Books / Test3-it should be over 3 megabytes but renders to a 740 KB PDF . It gives slightly better quality but still poor when examined-the close lines on the vernier scale become blurred when resolution is lost . talk ) 04 : 13, 4 March 2009 ( UTC)
