    Chapter VI Calibration of MLSS/TSS Chapter VI Calibration of MLSS/TSS The MLSS/TSS sensor has been factory calibrated before delivered, and the self-calibration can be carried out according to the following steps if required. The use of standard liquid is required for the calibration of the MLSS/TSS , taking two-point calibration as an example: 1.
  • Page 29 Chapter VI Calibration of MLSS/TSS The four-point correction step is basically the same as the two-point correction, and the selection of the correction points can be determined according to the actual measurement environment. They are usually the zero point, 0.25 times the range point, 0.5 times the range point and the full range point.
