PURPOSE:To surely set a slight or significant change in a variation numeric value, in a short time by reducing the variation of a displayed numeric value within a predetermined numeric range and increasing the variation beyond the range. CONSTITUTION:A timer operates by key-input, and after the predetermined time passed, a time-out signal occurs from a timer circuit 9. When a '+' key is pushed down, a CPU 10 increments one variable power rate. If one second or more has passed since the key was pushed down, the timer starts anew, and after the prescribed time, a timer output is obtained from the timer circuit 9. Then a variable power rate N is judged whether it is within the previously set range of variable power rates. If the rate N is within the range, the variation per unit, n=10, is stored in a RAM 6, whereas if the rate N is beyond the range, the variation per unit, n=1, is stored in the RAM 6. When the '+' key is pushed down, the rate is incremented. Thus, setting any numeric in any range is facilitated, and even the slight variation of a numeric value can be set surely. |
