Methods are disclosed for scaling and calibrating predetermined signals in apparatus for measuring and displaying predetermined characteristics of reciprocating machines. In the preferred embodiment, the methods comprise the calibrating of a pressure data acquisition and scaling system to eliminate inaccuracies due to temperature related changes in component values due to such things as component aging, the scaling of an amplified signal from a pressure transducer suitable for display purposes and the cancelling of an amplified output signal from the pressure transducer when zero pressure is applied thereto.
