ABSTRACT:
A weight scale with hybrid graduation includes an elastic element, a carrier mounted to the lower end of the elastic element, an indicator block mounted between the elastic element and the carrier, and a graduated housing for receiving the elastic element and the indicator block. The indicator block includes at least one auxiliary graduation. The graduated housing includes at least one primary graduation having a unit different from that of the auxiliary graduation. A weight of an object attached to the carrier is measured through vertical relative movement between the primary graduation and the auxiliary graduation to provide more accurate measuring result.
