<p>An electronic balance so structured that a menu list shows a combination of a basic menu list information having a tree structure of a large number of menu items predetermined and user menu list information stored in an nonvolatile memory by arbitrarily registering an arithmetic operation function frequently used by the user and the user can select a desired menu item from the menu list while the user moves the menu in the same layer or to a lower layer by performing determined key operations. Since the setting/resetting of a menu item, e.g., function 8, frequently used by the user is in a lower layer of the my menu having a high priority, selection can be performed with a smaller number of key operations than the selection by tracking the tree, e.g., menu group 2 ? function 8. With this, the work can be made efficient and the operations are simple. Therefore, the user performs operations without referring to the manual. Further since there is no change of order in the basic menu list other than the user menu list (29), selection of a menu item in such a list can be conventional one.</p> |
