2. Indicator (distance amplifying instrument) - Wikipedia

   en.wikipedia.org/wiki/Indicator_(distance...

   Ideal test indicator pushed. Prior to modern geared dial mechanisms, test indicators using a single lever or systems of levers were common. The range and precision of these devices were generally inferior to modern dial type units, with a range of 10/1000 inch to 30/1000 inch, and precision of 1/1000 inch being typical.

   The easiest method for measuring flatness is with a height gauge positioned on a surface plate. You must set up the part on three stands and find the minimum variation while adjusting them, just placing the part on the surface plate and using a dial indicator to find TIR on the opposite side of the part measures parallelism. Flatness is more ...

4. Dial (measurement) - Wikipedia

   en.wikipedia.org/wiki/Dial_(measurement)

   A dial is generally a flat surface, circular or rectangular, with numbers or similar markings on it, used for displaying the setting or output of a timepiece, radio, clock, watch, or measuring instrument. [1] Many scientific and industrial instruments use dials with pointers to indicate physical properties.

   Dial indicator, also known as a dial test indicator, dial gauge, or probe indicator an instrument used to accurately measure small linear distances. Feeler gauge: a simple tool used to measure gap widths. Gauge block, (also known as a gage block, Johansson gauge, slip gauge, or Jo block) a precision ground and lapped length measuring standard.

   Instead of using a vernier mechanism, which requires some practice to use, the dial caliper reads the final fraction of a millimeter or inch on a simple dial. In this instrument, a small, precise rack and pinion drives a pointer on a circular dial , allowing direct reading without the need to read a vernier scale.

   Trump’s primary work long ago became less about building anything than about branding himself and tending to his celebrity through a variety of entertainment ventures, from WWE to his reality-TV show, The Apprentice.

9. Surface plate - Wikipedia

   In this process, three approximately flat surfaces are progressively refined to precise flatness by manually rubbing them against each other in pairs with colouring matter in between, and then hand-scraping the high points. Any errors of flatness are removed by this scraping, since the only stable, mutually conjugate surface shape is a plane.
