The time study engineer stands where he may see every motion of the machine and every movement of the hand. The stop-watch is mounted on the same board as the time study sheet, so that they can be held in one hand while the times are jotted down with the other. The watch is set to 0, and the figure is entered against the first element. When the operation begins, the watch is started, and at the end of the first element the time is noted and set down. The watch is not stopped, and therefore each element time consists of the watch reading of the last element subtracted from the reading of the element under consideration.
