INSTRUMENT FOR COUNTING DURATION OF DIFFERENTIATED PHASES

摘要

The present invention relates to an instrument (1) for counting duration for differentiated phases comprising a plurality of duration recording means (11), each actuatable for the arming and disarming thereof by a first control means (13), said instrument comprising a general control means (12) for controlling, on the basis of a rest position where all said recording means are disarmed, the arming of a single one of them, selected by selection means (14) which said instrument comprises, and for furthermore controlling, at a terminal instant, the disarming of all said recording means. The instrument comprises switching means (15) devised, so as, during a command to arm one of said recording means, to trigger the disarming of all the other recording means (11) and retain the aggregate recording of the time counted on each of said recording means. The selection means are devised so as to be controlled by a user or/and by measurement means or/and by a signal, so as to trigger the arming of one of said recording means.
