View Catalog Sample Drawings Using a Dial Gauge a Target … WebVery accurate dial indicators can only resolve .000050" (1.27 microns) units of measurement. If the engineering specification for flatness of the component surface is two light bands a dial indicator does not have the capability to measure the lapped surface. In our industry it is more common for flatness to be specified in light band units.
