2) Replacement of copper crusher gauge (CUP) test equipment for piezoelectric based systems may be prohibitively expensive. CUP-based setups tent to be mechanical only, so do not require any form of computer or electrical supply. Even the measurement of the crushed gauges can be done with a mechanical micrometer.

A lump of lead, whose dimensions are greater than the gap of the crusher, is lowered through the crusher while the crusher is running. The lead is pulled back through the crusher very slowly to be sure that it is flattened as far as it can be. The narrowest point on the lead is then measured. This will be the SET POINT of the crusher.
