I posted a week or 2 or 3 ago re: how to read a Venier scale. A couple wreckers posted a couple different sites (e.g.:
But ....... the caliper I have is manufactured by ELCC (El Cheapo Caliper Company, i.e. General), and those teeny-tiny measurements still didn't jive. So I had to figure it out myself.
The websites assume that the primary caliper scale increments are the same as the Venier scale (i.e. the primary scale has 1/8" increments, and there are 8 Venier scale intervals). The resulting readout is then read in 1/64" increments (1/8*1/8).
But my ECCC caliper has a a primary scale that has 1/16" increments and 8 Venier increments, which clearly didn't produce results that jived w/ my rule. In this case, the 1/16" primary measurements and the 8 Venier increments result in readouts of 1/128" (1/8*1/16).
The measurements jive precisely. All is well in the universe. (Except the trolls.)
