Abstract
For calibration of a microprocessor-based electrical metering device, the scaled values of current and voltage inputs are presented on a display along side of the associated scaling factors. Soft keys on the display are used to increment or decrement the scaling factors to adjust the scaled values of the associated current or voltage to the value indicated by a precision reference meter which measures test values of current and voltage provided by a stable source. For analog inputs, both a zero scaling factor (offset) and a full scale factor (slope) are presented on the display adjacent the scaled analog value and can be separately adjusted by the soft keys.
