    • A preferred embodiment of a revolution counter tool and method employs an adapter shaft with input and output ends coupled in-line between a driven part and a driving part, and an intermediate portion between the input and output ends that is coupled to a rotary encoder and encoder circuit. A memory counter circuit maintains a count of turns and increments of the driven part by the driving part, and a reference setting circuit sets a reference setting of the memory counter circuit when a count is to be taken. The device body has a first portion mounting the adapter shaft with the rotary encoder, an intermediate housing containing the memory counter circuit, and a second portion at a distance from the first portion and of a sufficient mass that acts to orient the device body to a gravity-determined position as a reference position. The memory counter circuit receives output signals from the rotary encoder circuit and maintains a count relative to a reference setting using the reference position of the device body as indexed by gravity.
