Abstract
A voltage calibration routine for an oven, particularly a microwave oven, enables a field technician to enter a voltage calibration mode to display on the oven a pre-established default voltage to which the oven is calibrated. The technician then measures the actual line voltage applied to the oven and, if different than the default voltage displayed, inputs the actual line voltage into the microwave oven control, such as via a keypad. Thereafter, an offset value is calculated to correct the voltage measurement, allowing for a correct tap selection when the microwave oven is running. An additional function is available to check the oven voltage reading upon accessing a voltage reading mode wherein the oven measures and displays the line voltage which is compared to a volt meter reading such that a simple comparison can be made, while avoiding certain steps associated with the voltage calibration mode.
