Note: Accuracies are valid for measurements after calibration. Averaged numbers assume dithering and averaging of 100 single-channel
readings. Measurement accuracies are listed for operational temperatures within ±1 °C of internal calibration temperature and ±10 °C of
external or factory calibration temperature.
