Decimal-inch vernier height gage
The vernier height gage and vernier caliper are similar in operation. The height gage also has a sliding jaw; the fixed jaw is the surface plate with which the height gage is usually used. The gage can be used with a scriber, a depth gage attachment, or an indicator. The indicator is the most widely used and, generally, the most accurate attachment.
Measurements on the vernier height gage are read and set using the same procedure as with the vernier caliper.
