Bal-tec - Ball Diameter Calibration

The second approach to ball diameter calibration is the so-called absolute method. In absolute measurement, temperature is a first order error, that must be held at 68 °F (20 °C) exactly, or any variations must be compensated for. A micrometer or thread-driven measuring machine is an example of the absolute concept.
