Â This creates dial-in precision to 0.001″ accuracy that is totally repeatable and adds less than $100 Retail Value to the price of the target equipment. Software design of the display allows the unit to switch modes from fractional display 1/4, 1/8, 1/16, 1/32, 1/64 and then reads out in thousandths of an inch.
