An apparatus and method of automatically compensating gain versus temperature in a circuit of a measurement instrument that is subject to gain drift with temperature senses an ambient temperature for the circuit as a temperature voltage. The temperature voltage is scaled by a settable value representing a known temperature/gain characteristic for the circuit to produce a temperature correction voltage. The temperature correction voltage is subtracted from a reference voltage representing a gain for the circuit to produce a corrected reference voltage for the circuit.
