Dual Master or Single Master?
Dual Master tooling is set with two masters, one at each end of the tolerance, and works with any two-master readout. Single Master tooling is set on one master at nominal and is matched to a single-master readout, such as the Air Gage Pro M5-L or M5-H that replaces Dimensionair readouts. Compare single and dual master.
