(003A,0211)>>Channel Sensitivity Units Sequence1C A coded descriptor of the Units of measure for the Channel Sensitivity. Only a single Item shall be permitted in this sequence. (see C.10.9.1.4.2) Required if Channel Sensitivity (003A,0210) is present.
(003A,0212)>>Channel Sensitivity Correction Factor1C Multiplier to be applied to encoded sample values to match units specified in Channel Sensitivity (003A,0210) (e.g., based on calibration data) (see C.10.9.1.4.2) Required if Channel Sensitivity (003A,0210) is present.
(003A,0213)>>Channel Baseline1C Offset of encoded sample value 0 from actual 0 using the units defined in the Channel Sensitivity Units Sequence (003A,0211). Required if Channel Sensitivity (003A,0210) is present.

(003A,0215)>>Channel Sample Skew1C Offset of first sample of channel from waveform multiplex group start time, in samples (see C.10.9.1.4.3) Required if Channel Time Skew is not present.
(003A,0218)>>Channel Offset3 Additional offset of first sample of channel to be used in aligning multiple channels for presentation or analysis, in seconds (see C.10.9.1.4.3)
