This caliper takes inside, outside, depth, and centering readings.

The vernier caliper has a fixed (main) scale and a movable (vernier) scale. The vernier scale moves over the main scale rule to give a fractional measurement which is added to the measurement of the main scale to achieve a more accurate result. The main scale may be marked in inches, millimeters, or both.

The vernier scale may be marked in inches or millimeters. The 531-128 has a dual vernier scale, with both inch and metric measurements, on the upper and lower edges, respectively. The dual scale enables this caliper to measure a greater diversity of item types.

Model 531-128 has a spring loaded thumb clamp to control the sliding movement of the vernier scale.
