ABSTRACT:
An electronic hand-held resistor value decoding calculator is disclosed. The calculator includes a keypad comprising a keypad housing and an array of ten manually operated keypad switches for receiving input signals. Each of the keypad switches has a numeral from zero through nine associated therewith and is uniquely colored so as to correspond to the colors of the International Resistor Color Code. The calculator also includes an ALU operatively connected to the keypad switches for performing mathematical calculations on the input signals for determining the value of a resistor. A display is operatively connected to the ALU for displaying the computational result of the mathematical computations on the input signals. The keypad switches are adapted to receive three input signals, each of the input signals being a single keystroke and each of the keystrokes representing a single color band on the resistor.
