Abstract
A system and method for compensating for thermal drift. A temperature is measured in a meter as a temperature voltage. The temperature voltage is converted to a digital signal. The digital signal is processed to generate an offset voltage in response to the digital signal. The offset voltage is applied as an input to an amplifier. The amplifier receives as a second input a gauge voltage. An output is generated from the meter that corrects the gauge voltage using the offset voltage to compensate for thermal drift.
