Note: Accuracies are valid for measurements following an internal calibration. Measurement accuracies are listed for
operational temperatures within ±1 °C of internal calibration temperature and ±10 °C of external or factory-calibration
temperature. Temp drift applies only if ambient is greater than ±10 °C of previous external calibration.
