摘要： A method of making a tube spring manometer measurement system is disclosed. The system, comprising a tube spring, display assembly and at least one operating member which actuates said display assembly, e.g. a tie rod, is mounted and assembled to form a functional assembly. A predetermined reference pressure is then applied to the tube spring. The deflection of the display assembly caused by said reference pressure is compared to a theoretical deflection. If the difference between a theoretical deflection associated with said reference pressure and the observed actual deflection is excessive, local heat is supplied by means of a laser beam to at least one operating member and/or said tube spring, thereby removing material and/or altering the internal tension thereof. These changes are utilized to influence the range and/or zero baseline of the instrument. Heat is supplied without force or contact, so that the effect of the heat can be monitored directly and discontinued at exactly the moment the desired display accuracy is attained.
