A reduced error measurement system for use in, for example, an appliance control system includes a multiplexor, a plurality of sensors coupled to the multiplexor, and a single amplifier circuit having an impedance path. The multiplexor is configured to selectively place one of the sensors into the impedance path of the amplifier. A transfer function of an amplifier circuit is dependent upon a selected sensor response when placed into the circuit, thereby allowing a controller to make control decisions based upon a voltage output of the single amplifier, thereby reducing errors attributable to a plurality of amplifier channels. An adjacent channel calibration technique is used to calibrate a hard mounted sensor to an integrated circuit that applies a calibrated offset value determined with a removable sensor coupled to the integrated circuit to the hard mounted sensor.
