Electronic weighing scales with user-configurable check weigh function and methods of using the same

1. An electronic foodservice weighing scale for weighing a plurality of different foodstuffs in connection with food preparation, the scale comprising:

a user interface communicatively coupled to the scale, the user interface including a plurality of check weigh memory buttons each independently selectable for programming a target weight for a check weigh operation;

wherein the scale is configured to perform the check weigh operation in response to a user selection of one of the plurality of check weigh memory buttons, wherein the check weigh operation includes comparing a measured weight of a foodstuff placed on the scale to a programed target weight range associated with the user-selected check weigh memory button and corresponding to the type of foodstuff and/or type of recipe ingredient placed on the scale, wherein the target weight range is a programmed target weight plus or minus a programmed target weight tolerance;

wherein the scale is designed and configured for the programmed target weight tolerance for each of the plurality of check weigh memory buttons to be independently programmable by a user to thereby allow for tighter target weight tolerances for more expensive ingredients and/or more precise recipes and looser target weight tolerances for less expensive ingredients and/or less precise recipes.

2. The electronic weighing scale of claim 1 , wherein the programmed target weight tolerances are configured to be programmed by performing steps that include:

entering a target weight tolerance setting mode;

receiving a user selection of one of the plurality of check weigh memory buttons; and

receiving a user selection to increase or decrease the target weight tolerance setting associated with the user-selected check weigh memory button.

3. The electronic weighing scale of claim 1 , wherein the target weight for each of the plurality of check weigh memory buttons can be independently programmed by pressing and holding a selected one of the plurality of check weigh memory buttons for a predetermined duration of time.

4. The electronic weighing scale of claim 3 , wherein the user interface includes a plurality of erasable spaces located below a corresponding check weigh memory button for allowing a user to add an annotation that indicates what a particular check weigh memory button has been configured for.

5. The electronic weighing scale of claim 1 , wherein each of the plurality of check weigh memory buttons configured as a one-touch multi-functional control element, wherein one of a plurality of functions are selectable according to a duration of time the selected check weigh memory button is depressed, the check weigh memory buttons configured to initiate the programming of the target weight when one of the check weigh memory buttons is depressed for a predetermined duration of time and initiate a check weigh mode to compare a measured weight to a pre-programmed target weight associated with a selected check weigh memory button when the selected check weigh memory button is depressed for a duration of time less than the predetermined duration of time.

6. The electronic weighing scale of claim 1 , wherein the scale is configured to perform the check weigh operation in response to a user selection of the plurality of check weigh memory buttons, wherein the check weigh operation includes comparing a measured weight of an object to a target weight range.

7. The electronic weighing scale of claim 6 , wherein the user interface includes a check weigh visual indicator configured to emit at least two different colors of light and/or temporal patterns of light according to whether the measured weight is above, below, or within the target weight range.

8. The electronic weighing scale of claim 7 , wherein the check weigh visual indicator is configured to emit a first color of light when the measured weight is below the target weight range, a second color of light different than the first color of light when the measured weight is within the target weight range, and a third color of light different than the first and second colors of light when the measured weight is above the target weight range.

9. The electronic weighing scale of claim 6 , wherein the user interface includes a numerical display portion configured to display a measured weight of an object and a check weigh visual indicator configured to emit light according to whether the measured weight is above, below, or within the target weight range.

10. The electronic weighing scale of claim 9 , wherein the check weigh visual indicator substantially surrounds the numerical display portion.

11. The electronic weighing scale of claim 10 , wherein the check weigh visual indicator includes a plurality of discrete light emitting elements spaced around a perimeter of the numerical display portion, including at least one light emitting element on a top, bottom, left, and right sides of the numerical display portion.

12. The electronic weighing scale of claim 9 , wherein the check weigh visual indicator is an elongate light emitting portion adjacent the numerical display portion, the elongate light emitting portion having a length that is greater than or equal to a height or width of the numerical display portion.

13. The electronic weighing scale of claim 1 , wherein the scale is a washdown foodservice scale.

14. The electronic weighing scale of claim 1 , wherein each of the plurality of check weight memory buttons are selectable for programming a target weight for the check weigh operation by pressing and holding one of the check weigh memory buttons for a predetermined duration of time while an object having the target weight is being weighed by the scale.

15. The electronic weighing scale of claim 14 , wherein the target weight for each of the plurality of check weigh memory buttons can be independently programmed by pressing and holding a selected one of the plurality of check weigh memory buttons for the predetermined duration of time.
