With the help of caliper gauges, the status “good”, “reject” or “rework” is decided during serial measurements.
This way no faulty part leaves the production line.
Like the plug gauge, the caliper gauge has a good side and a red marked reject side.
The good side represents the maximum dimension and is thicker on the gauge than the reject side.
The diameter of a shaft must not be larger than the dimension of the good side.
To prevent the shaft diameter from being to small, the reject side, which is the minimum dimension, must not fit over the shaft.
