In motion the salinity is considered ±0.005psu. There were no salinity calibration samples and there is no history for these sensors since their most recent recalibration, so no comment can be made on the accuracy. ---------------------------------------------------------------------- *CALIBRATION $TABLE: CORRECTED CHANNELS !
