resistance imbalance. The hardware and software errors include
calibration of the system, and non-linearity of the ADC. For the sake of
the calculations the resolution of the ADC was assumed to be at least 16
bits (use of the 10Hz, 50Hz, and 60Hz filter frequencies). Note: The
250Hz frequency should not be applied to thermocouple or RTD inputs if
accuracy is a concern.
