Note:Accuracies are valid for measurementsfollowing an internal E Series calibration. Averaged numbers assumedithering and averaging of
100single-channel readings. Measurement accuracies arel istedfor operational temperatures within ±1 °C of internal calibration tem perature
and±10 °C of external or factory calibration temperature.
