Note: Accuracies are valid for measurements following an internal E Series 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.
