Steinmeyer Dial Passameter 3901 Passameters are adjustable snap gauges which are mostly used for measuring and testing of round-cut and milled parts. They replace a large number of fixed gauges whilst this device also has the advantage of a number display if there are deviations to the preset value. The Passameter 3901 requires no additional display device and can be used immediately.Gageblocks, gages, or a selected test piece is used to set the instrument to the nominal size. For this purpose, turn the adjusting nut to move the adjusting bolt in the axial direction, until the pointer approximates zero. Tighten the clamping nut to prevent an unintentional displacement.The exact zero adjustment is made by turning the knurled knob on the rear panel. The dial adjustment can be fixed by means of the set screw.
