Abstract

All such measurements form a part of the science of metrology especially concerned with measurement of length, angle, datum, circle, a line and so on. Of these length is of fundamental importance since angular measurements may be carried out by the appropriate use of linear measurement in combination. Specifications of the equipment (profile Projector): Measuring Travel - 10" (250 mm) horizontal (X) • 4" (100 mm) vertical (Y) • 2.5" (60 mm) focus with Quick Release on X-Axis Precision Measuring Stage - 5" x 16" (125 x 400 mm) nickel-plated top plate Digital Screen Protractor On 3550 Series - angular readings to 1 minute of arc Duplex Fiber Optic Surface Illumination 14" Frosted Glass Screen - with 30,60, and 90 degree cross lines Helix - +/-6° via lamp house displacement
