Abstract
A weighing instrument that incorporates a formula parsing engine and keys for entering a formula. One key is assigned for entering the current mass reading into the formula, based on which a calculated result is obtained and displayed. This result changes according to the entered formula for each weight that is placed on the weighing pan.
Claims25
An electronic scale, comprising:
- a weighing system that determines a measured mass of an object that is received by the scale;
- an electronic system including a digital processing system that calculates a formula result from the measured mass of the object according to a formula;
- and
- numerical value keys and mathematical operator keys to manually enter numerical values and mathematical operators of the formula into the electronic system.
