Looks like they did it right to me.... 12.3.3.1 Each control valve shall be operated annually through its full range and returned to its normal position. 12.3.3.5.2 A distinctive signal shall indicate movement from the valve's normal position during either the first two revolutions of a hand wheel or when the stem of the valve has moved one-fifth of the distance from its normal position .
