摘要:
An improved data entry and control arrangement for an appliance which includes an electronic display having a plurality of digits. User actuable up and down keys enable the user to adjust the value displayed. The control changes the display by a first amount, for example, one minute for a time display, in response to each momentary actuation of an up or down key. In response to continuous actuation, the control, after initially changing the display by the first amount, then switches the least significant digit of the display to zero and thereafter periodically changes the display by a second amount evenly divisible by ten, such as for example 10 minutes. The preferred update interval between changes is on the order of 0.45 seconds duration. The control also enables the user to change the update interval.
